Earth Changes
Earth Changes is a term coined by American psychic Edgar Cayce in the 1930s to describe a series of prophesied cataclysmic events reshaping Earth's surface through mechanisms such as axial pole shifts, widespread inundations, intensified seismic and volcanic activity, and the submersion or emergence of landmasses, purportedly culminating in spiritual renewal for humanity.[1] These visions, drawn from Cayce's trance-induced readings, anticipated initial upheavals beginning in the mid-20th century and accelerating toward the turn of the millennium, including the fracturing of the U.S. West Coast and the formation of new inland seas.[2] The concept gained wider traction in New Age circles through figures like Gordon-Michael Scallion, who from the 1980s onward produced detailed "future maps" depicting post-cataclysm geographies, such as the inundation of much of Europe's coastlines and the rise of new mountain ranges in the Atlantic.[3][4] Despite their influence on alternative spirituality and survivalist preparations, Earth Changes prophecies rely on unsubstantiated visionary claims rather than observable data or geophysical models, with specific timelines—such as major U.S. continental disruptions by 2001—failing to materialize amid ongoing tectonic stability governed by slow plate movements averaging centimeters per year.[5] Scientific assessments attribute long-term planetary alterations to verifiable processes like orbital variations and mantle convection, not the rapid, apocalyptic shifts envisioned, rendering the predictions inconsistent with empirical records of Earth's 4.5-billion-year history.[6] Key controversies center on the absence of precursor indicators in seismic, magnetic, or climatic monitoring networks, underscoring the speculative nature of sources rooted in personal revelations over reproducible evidence.[4]Conceptual Foundations
Definition and Core Claims
The term Earth Changes refers to a set of prophesied geophysical, climatic, and societal transformations of the planet, as articulated in the trance readings of American psychic Edgar Cayce (1877–1945). Coined in the context of Cayce's approximately 14,000 documented readings from the 1920s to 1940s, the concept encompasses predictions of cataclysmic events driven by shifts in the Earth's crust, axis, and overall geophysical stability, often tied to spiritual or karmic principles. Fewer than 20 readings explicitly address physical manifestations of these changes, framing them as part of a broader cycle of planetary renewal rather than isolated disasters.[7] Core claims include a tilting or shifting of the Earth's poles, which Cayce described as altering magnetic fields and triggering widespread seismic activity, volcanic eruptions, and coastal inundations. Specific predictions outlined in readings such as 3976-15 (1934) and 1152-11 (1936) foresee the western United States fracturing, with waters from the Great Lakes flowing into the Gulf of Mexico; the submersion of much of Japan; changes to European landmasses "in the twinkling of an eye"; and the emergence of Atlantis remnants near Bimini in the Bahamas around 1968–1969. These events were projected to intensify from the late 1930s through 1998, potentially culminating in a full axis realignment by 2001, reversing climatic zones—rendering frigid areas tropical and vice versa.[8][7][9] Cayce's readings portray these changes as conditional, influenced by collective human consciousness and moral development, suggesting that spiritual attunement could mitigate their severity or shift their nature toward metaphorical or internal transformations rather than purely physical ones. Proponents interpret ongoing phenomena like increased earthquake frequency or polar magnetic shifts as partial fulfillments, though no empirical evidence supports the scale of sudden, global cataclysms described, and many timeline-specific events—such as Atlantis's rise or Japan's partial destruction—have not occurred as predicted.[10][8]Historical and Cultural Precursors
Plato's dialogues Timaeus and Critias, composed around 360 BCE, introduced the legend of Atlantis, portraying it as a powerful island empire beyond the Pillars of Hercules that was utterly destroyed in a single day and night by violent earthquakes and floods, with the land sinking into the sea.[11][12] This account, attributed by Plato to Solon via Egyptian priests, emphasized moral decline leading to divine retribution through geophysical catastrophe, motifs that echoed earlier Mesopotamian flood narratives like the Epic of Gilgamesh (c. 2100–1200 BCE), where Utnapishtim survives a global deluge unleashed by the gods. While scholars debate Atlantis as allegory for hubris or distorted memory of events like the Minoan eruption (c. 1600 BCE), its depiction of rapid continental submersion prefigured later speculative theories of crustal displacement and sudden landmass alterations.[13] In Judeo-Christian traditions, the Genesis flood narrative (c. 6th–5th century BCE composition) describes a worldwide inundation that reshaped the earth's surface, with waters prevailing for 150 days and receding over months, leaving only Noah's ark survivors. Prophetic texts amplify this with eschatological visions of upheaval: Isaiah 24:19–20 foretells the earth breaking apart, reeling like a drunkard, and displaced from its orbit; Joel 2:30–31 predicts blood, fire, and pillars of smoke amid cosmic darkening; and Revelation 6:12–14 evokes a great earthquake flattening mountains and islands, with the sky receding like a scroll. These passages, interpreted across millennia as harbingers of divine judgment involving tectonic and atmospheric disruptions, parallel motifs in other Abrahamic apocalypses, such as the Book of Enoch's (c. 300–100 BCE) accounts of pre-flood cataclysms tied to fallen angels and elemental chaos. Broader cultural precedents appear in Hindu scriptures, where the Puranas describe cyclical yugas culminating in pralaya, a dissolution phase marked by earthquakes, floods, and fire consuming the world before renewal—e.g., the Mahabharata (c. 400 BCE–400 CE) narrates Kalki ending the Kali Yuga with global upheaval. Similarly, Mesoamerican codices like the Maya Popol Vuh (transcribed c. 1550s from oral traditions) recount multiple world destructions by flood and earthquake across prior creations. Indigenous North American oral histories, such as Hopi prophecies of previous worlds ended by fire, ice, and flood, encode memories of megafaunal extinctions and sea-level rise post-Last Glacial Maximum (c. 20,000–10,000 BCE). These diverse traditions, often rooted in oral or textual records of paleoclimatic events like the Younger Dryas cooling (c. 12,900–11,700 years ago), supplied archetypal frameworks for envisioning periodic, transformative earth alterations driven by natural or supernatural forces.Primary Proponent: Edgar Cayce
Biographical Context and Methodology
Edgar Cayce was born on March 18, 1877, near Hopkinsville in Christian County, Kentucky, to Leslie Burr Cayce, a tobacco wholesaler and farmer, and Carrie Elizabeth Major Cayce.[14] As a child, Cayce exhibited unusual abilities, including claims of seeing and interacting with deceased relatives and absorbing knowledge directly from books by sleeping on them, though these accounts originate primarily from his own recollections and supporters.[15] He was deeply religious from an early age, memorizing much of the Bible by age 10 and aspiring to become a minister, but formal education was limited, with only an eighth-grade completion due to family financial constraints and personal disinterest in traditional schooling.[14] Cayce worked various jobs in his youth, including as a bookstore clerk and photographer's assistant in Hopkinsville, before briefly attending the Normal College in Bowling Green, Kentucky, in 1900.[16] In 1901, at age 24, Cayce lost his voice due to laryngitis while working as a salesman in Bowling Green; under hypnosis induced by local hypnotist Al Layne, he entered a trance state and prescribed a treatment that reportedly restored his speech, marking the first documented "reading."[16] This led to a partnership with Layne, who used Cayce's trances for diagnostic readings on patients, initially focusing on health issues through suggestions of remedies like osteopathic adjustments or herbal treatments.[17] Cayce married Gertrude Evans in 1903, and the couple relocated multiple times, including to Alabama and Ohio, where he supported himself through photography and insurance sales while expanding readings to address personal, business, and later esoteric topics such as reincarnation and ancient histories.[14] By the 1920s, demand grew, attracting figures like Arthur Lammers, who prompted readings on metaphysical subjects, shifting Cayce's focus toward spiritual and prophetic interpretations.[18] In 1925, Cayce settled in Virginia Beach, Virginia, establishing a hospital in 1928 for applying reading-based therapies and founding the Association for Research and Enlightenment (A.R.E.) in 1931 as a nonprofit to archive, study, and disseminate his readings.[14][19] The A.R.E. collected transcripts of over 14,000 readings conducted between 1901 and 1944, covering diagnostics for thousands of individuals, though Cayce limited sessions to two per week to avoid health strain, which nonetheless contributed to his physical decline from overwork and a 1944 stroke.[17] He died on January 3, 1945, in Virginia Beach at age 67, leaving the A.R.E. to continue research into his materials, including prophecies on global changes derived from trance insights.[14] Cayce's methodology involved self-inducing a trance by reclining, loosening clothing, and focusing inwardly, often entering a sleep-like state within minutes where his voice shifted to a monotone for delivering information.[17] A conductor—typically a stenographer or associate—provided the subject's name, location, and query (e.g., for health: "We are here seeking information on the entity's condition"); Cayce responded without prior knowledge, diagnosing ailments, suggesting treatments, or addressing prophecies by claiming access to a universal subconscious or "Akashic records"—a purported ethereal repository of all human experience.[16][17] Readings concluded with a suggestion to awaken, after which Cayce recalled nothing, relying on transcripts for review; while health readings emphasized holistic approaches like diet and vibration therapy, prophetic ones, including Earth Changes, drew from visions of past civilizations like Atlantis, though empirical verification of accuracy remains absent, with successes anecdotal and failures attributed by proponents to conditional interpretations.[18][17]Specific Prophecies and Readings
In reading 3976-15, given on January 19, 1934, Cayce forecasted geological upheavals including widespread fracturing of the earth's surface, with initial disruptions manifesting as a physical severance along the west coast of the United States from the Baja California region northward.[7][20] The reading specified that these events would disrupt economic and social structures, particularly affecting transportation and trade routes, while urging preparation through spiritual and communal efforts rather than physical escape.[20] Reading 378-16, from 1932, connected such changes to a broader pole shift, describing it as the conclusion of a 25,000-year cycle where the earth's axis would realign, initiating climatic reversals and continental adjustments akin to those that submerged Atlantis and Lemuria in prior epochs.[8] Cayce indicated this shift would accelerate between 1958 and 1998, potentially causing submersion of landmasses in the Pacific (including parts of Japan) and elevation of areas in the Atlantic, such as near Bimini, where remnants of Atlantean technology would surface.[7][21] Additional readings, such as 5748-6 and 5750-1, prophesied the discovery of three "Halls of Records" containing Atlantean archives during these transformations—one beneath the Sphinx in Egypt, another in the Yucatan Peninsula, and a third near Bimini—intended to reveal historical and spiritual knowledge to guide humanity through the turmoil.[22] Cayce portrayed the changes as conditional, influenced by global consciousness, with potential for reduced severity if humanity achieved greater attunement, though core geophysical realignments remained tied to cosmic cycles.[10] Fewer than 20 of Cayce's over 14,000 readings addressed physical earth changes explicitly, emphasizing their role in ushering a transition to a "New Age" rather than mere destruction.[7]Other Proponents and Variations
Gordon-Michael Scallion and Map-Based Visions
Gordon-Michael Scallion (1942–2002) was an American futurist and self-described spiritual visionary who gained prominence in the 1990s for promoting Earth Changes through illustrated maps forecasting global cataclysms.[3] Following a personal spiritual awakening in the late 1980s, Scallion claimed to receive clairvoyant visions of planetary upheavals, including axis shifts, massive earthquakes, volcanic activity, and sea-level rises triggered by magnetic pole reversals.[4] [23] He positioned these events as part of a "Tribulation" period leading to spiritual renewal, disseminating his forecasts via the Matrix Institute's Earth Changes Report newsletter and proprietary cartographic publications.[24] Scallion's most influential contributions were his prophetic maps, beginning with the 1992 "Future Map of the United States" and expanding to the 1993 "Future Map of the World," revised in 1996.[25] [26] These depicted a radically reconfigured planet post-2000, with North America's eastern and western seaboards largely inundated, forming new inland seas (e.g., the "Mississippi Sea" and "Great Lakes Basin" expansions) and isolating regions like the Rocky Mountains as a central landmass.[3] Globally, the maps illustrated Europe's partial fragmentation, Africa's uplift with new mountain ranges, and Asia's reconfiguration, including Japan's near-total submersion and the emergence of land bridges across the Pacific.[27] [28] Annotations on the maps specified causal mechanisms, such as three phases of pole shifts between 1998 and 2001, culminating in 30–50% of the world's population displacement by tsunamis and climatic disruptions.[26] [29] Unlike textual prophecies, Scallion's map-based approach emphasized visual specificity, identifying "safe zones" (e.g., parts of the U.S. Midwest and Appalachians) amid flooded urban centers like New York and Los Angeles.[3] He linked these visions to broader metaphysical narratives, including the appearance of a "blue star" signaling cosmic intervention and the rise of "Golden Cities" as post-cataclysm refuges.[3] By 1995, Scallion forecasted initial tribulations escalating annually, with continent-altering events by 1997, though he later adjusted timelines amid non-occurrence.[23] His materials, printed on large-scale posters, were marketed to subscribers and collectors, influencing survivalist communities despite lacking empirical geological backing.[30]Additional Figures and Collective Interpretations
Ruth Montgomery, a former Washington journalist turned psychic author, channeled communications from spiritual "Guides" that echoed Cayce's earth changes theme, predicting a dramatic polar axis shift in the early 21st century that would trigger massive geological upheavals, including widespread flooding and coastline alterations across continents.[31] Her 1999 book The World to Come detailed these visions, specifying that the shift—initially foreseen for the late 20th century but revised to a later date—would spare higher elevations while submerging low-lying regions, with safe zones identified in parts of the American Midwest and elevated European areas.[32] Montgomery's predictions, derived from automatic writing sessions, emphasized a karmic purification through cataclysm, aligning with New Age narratives of spiritual evolution amid physical disruption, though lacking empirical validation.[33] Mark L. Prophet, founder of the Summit Lighthouse organization in 1958, incorporated earth changes into his dictations as an "Ascended Master," forecasting intensified seismic activity, volcanic eruptions, and climatic disruptions as precursors to a new age of enlightenment by the early 21st century.[34] In prophecies delivered through trance states, Prophet warned of global chaos from pole migrations and tectonic strains, urging followers to prepare spiritually rather than geographically, with events tied to unresolved human karma rather than purely geophysical causes.[35] These visions, continued by his wife Elizabeth Clare Prophet after his 1973 death, blended Christian mysticism with esoteric geology, predicting upheavals that would reshape nations but had not materialized by the projected timelines.[36] Collective interpretations among proponents synthesize these individual visions into broader frameworks, often mapping overlapping safe havens—such as the Appalachian highlands or central Asian plateaus—derived from cross-referencing Cayce's, Scallion's, and Montgomery's channeled data to forecast a unified cataclysm involving a 20- to 45-degree crustal displacement.[4] New Age communities and futurist publications interpret these convergences as evidence of a shared psychic insight into cyclical earth resets, potentially triggered by solar activity or inner earth dynamics, though skeptics attribute the consistencies to cultural diffusion of pseudoscientific ideas rather than prescience.[3] Such syntheses, disseminated via newsletters and maps in the 1980s-1990s, influenced survivalist preparations but have faced scrutiny for failing to align with observed geophysical stability, as measured by satellite gravimetry and paleomagnetic records showing gradual, not abrupt, polar wander over millennia.[37]Detailed Predictions
Geological and Oceanic Shifts
Edgar Cayce's readings described extensive geological upheavals involving the submersion of large landmasses and the emergence of new territories, particularly along coastal regions of the Americas, Europe, and Asia.[38] In specific prophecies, he foresaw the western portions of the United States, including cities like Los Angeles and San Francisco, sliding into the Pacific Ocean due to intensified seismic activity, with safe zones shifting inland to areas such as parts of Nevada and Arizona.[39] [40] Cayce also predicted the destruction of New York City through earthquakes, alongside the rising of ancient landmasses resembling Atlantis off the eastern U.S. seaboard around 1968 or 1969.[41] [39] Oceanic shifts in Cayce's visions included dramatic sea level incursions transforming current coastlines into seabeds, with new lands emerging in the Atlantic and Pacific Oceans.[42] He anticipated initial disruptions in the South Pacific, such as the breaking up of landmasses followed by sinking and rising terrains, potentially triggered by a shift in the Earth's polar axis becoming evident between 2000 and 2001.[38] These changes were linked in his readings to karmic cycles and prior Atlantean misuse of crystal technology, projecting a timeline commencing around 1958 and intensifying through the late 20th century.[43] Gordon-Michael Scallion expanded on similar themes through visionary maps depicting phased magnetic pole reversals between 1998 and 2001, leading to widespread coastal inundation and continental reconfiguration.[26] His predictions illustrated the formation of new inland seas across North America, the submergence of eastern U.S. coastlines up to the Appalachians, and the creation of island chains from elevated terrains in Europe and the Mediterranean, including sinking of cities like Venice and Rome.[28] [4] Scallion's scenarios incorporated rising sea levels and tectonic fractures, resulting in a fragmented global landmass with new straits and peninsulas, influenced partly by Cayce's earlier prophecies but emphasizing rapid, cataclysmic pole-induced alterations.[3]Climatic and Polar Changes
Edgar Cayce's readings anticipated a cataclysmic shift in the Earth's rotational axis, driven by geophysical upheavals, that would reverse climatic zones worldwide. In reading 3976-15, delivered on January 19, 1934, he specified that disruptions in the Arctic and Antarctic would trigger volcanic activity in equatorial regions, culminating in a pole shift where "frigid or the semi-tropical [areas] will become the more tropical, and moss and fern will grow."[20] This transformation implied warmer conditions in polar vicinities and cooler shifts elsewhere, with initial signs expected between 1958 and 1998.[7] Cayce linked these changes to broader earth disruptions, including partial melting of ice caps in Greenland, Iceland, and Antarctica, which would elevate global temperatures and sea levels over time.[9] Gordon-Michael Scallion, drawing from visions starting in 1979, projected magnetic pole reversals of 20 to 45 degrees between 1998 and 2001, exacerbated by global warming, nuclear tests, and technological excesses.[4] His forecasts included accelerated polar ice melt from intensified volcanism, yielding extreme weather anomalies, expanded deserts in former temperate zones, and novel tropical bands across North America and Europe as depicted in his 1993 "Future Map of the World."[27] Scallion emphasized rapid climatic relocations, such as inland flooding creating humid microclimates and aridification of coastal lowlands, contrasting with gradual anthropogenic models by positing sudden, tectonically induced overhauls.[3] These predictions from Cayce and Scallion converge on pole-induced climatic inversions but diverge in mechanisms and pace, with Cayce tying events to spiritual cycles and Scallion to human-induced stressors; neither materialized as outlined by their projected timelines.[8]Scientific Scrutiny
Mechanisms of Actual Earth Dynamics
The lithosphere of Earth is divided into tectonic plates that float on the semi-fluid asthenosphere and move relative to each other, constituting the core mechanism of global geological dynamics.[44] These plates, numbering about a dozen major ones, interact at boundaries where divergence, convergence, or lateral sliding occurs, shaping continents, ocean basins, and mountain ranges over geological timescales.[45] Movement rates average 1 to 10 centimeters per year, comparable to human fingernail growth, as measured by GPS and seafloor magnetic anomalies.[46] Driving this process is mantle convection, where hotter, less dense material rises and cooler material sinks, powered by two principal internal heat sources: primordial heat retained from Earth's formation approximately 4.5 billion years ago and radiogenic heat from ongoing radioactive decay of elements like uranium-238, thorium-232, and potassium-40 in the mantle and core.[47] This heat flux, estimated at about 44 terawatts to the surface, sustains the convective currents without reliance on external solar input for deep interior processes.[48] Slab pull—where dense, subducting oceanic lithosphere pulls plates downward—and ridge push from elevated mid-ocean ridges contribute to motion, though convection remains the overarching force.[49] Earthquakes result primarily from the accumulation and sudden release of elastic strain energy along plate boundaries, particularly at transform faults like the San Andreas or convergent zones like the Himalayan front.[5] Over 90% of seismic activity occurs at these interfaces, with magnitudes scaling to fault rupture length; for instance, the 1960 Chile earthquake (Mw 9.5) released energy equivalent to 2.5 gigatons of TNT due to subduction of the Nazca Plate under South America.[45] Volcanism arises from partial melting of mantle or crustal rock: at divergent boundaries, decompression melting generates basaltic magma as in Iceland's Mid-Atlantic Ridge activity; at convergent margins, water from subducting slabs lowers melting points, producing andesitic eruptions like those in the Pacific Ring of Fire, where over 75% of active subaerial volcanoes cluster.[50] Hotspot volcanism, independent of plate boundaries, such as Hawaii's chain, stems from fixed mantle plumes piercing overriding plates.[51] Polar dynamics involve distinct processes: geographic poles exhibit minimal axial tilt variation beyond Milankovitch cycles (precession, obliquity, eccentricity) operating over 20,000 to 100,000 years, with no evidence of rapid true polar wander exceeding 1 degree per million years in recent geological records.[52] Magnetic poles, generated by the geodynamo in the liquid outer core's convective flows of molten iron, drift due to flux patches at the core-mantle boundary; the north magnetic pole has accelerated from 15 km/year in the 1990s to about 45-55 km/year toward Siberia since 2000, tracked via satellite models like the International Geomagnetic Reference Field.[53] Full geomagnetic reversals occur irregularly every 200,000 to 300,000 years on average, lasting thousands of years, but do not involve crustal displacement or cataclysmic surface effects.[54] Oceanic shifts, including sea-floor spreading at rates of 2-5 cm/year, gradually alter basin geometries but lack mechanisms for sudden, continent-scale inundations.[55]Evidence Against Cataclysmic Scenarios
Geophysical observations confirm the stability of Earth's rotational axis over millennia, with variations limited to gradual precession cycles occurring over approximately 26,000 years and small nutation effects, precluding any mechanism for sudden, cataclysmic tilts or flips.[56][57] The absence of significant torque from internal or external forces, such as uneven mass distribution or impacts, further supports this stability, as Earth's oblate spheroid shape and angular momentum resist abrupt reorientations.[58] Plate tectonics governs continental movements at rates of 1-10 centimeters per year, resulting in shifts measurable only over millions of years, with no paleontological or stratigraphic evidence indicating rapid, wholesale displacements of landmasses in recent geological history.[59][60] Theories proposing sudden crustal slips, such as those invoking ice imbalances, lack supporting data from hotspot tracks or paleomagnetic records, which instead align with gradual subduction and seafloor spreading.[61] Geomagnetic reversals, while documented in the rock record, unfold over 1,000 to 10,000 years without triggering mass extinctions, seismic upheavals, or climatic collapses, as fossil and sediment layers show continuous biological succession across reversal boundaries.[62][63] Current field weakening, observed since the 1840s via global observatories, proceeds slowly and does not correlate with increased volcanism or tectonic instability.[64] Seismological and geodetic monitoring by networks like the USGS and GPS arrays reveals no precursors to continent-scale disruptions, with earthquake magnitudes historically insufficient to induce global reconfiguration, as energy dissipation occurs locally rather than propagating to crustal-wide failures.[60] The geological record, including ice cores and sediment layers, exhibits uniformitarian patterns of erosion and deposition over extended periods, contradicting claims of recent hyper-catastrophic events that would leave unmistakable iridium spikes or chaotic unconformities absent in post-Pleistocene strata.[65]Evaluation of Outcomes
Timeline of Failed or Absent Events
Gordon-Michael Scallion predicted that by 2001, massive geophysical upheavals would reshape North America, including the inundation of coastal regions, the formation of new inland seas, and the collapse of terrain along fault lines in the western United States, as depicted in his 1993 "Future Map of the World."[3] These events failed to occur, prompting Scallion to revise his timeline to 2012 in a 2002 update, after which no such transformations materialized either.[3] Similarly, Edgar Cayce's readings anticipated a shift in the Earth's axis by 2001, accompanied by climatic reversals and widespread disruptions, marking the culmination of changes initiated in the 1958–1998 period.[8] No axial shift or associated cataclysms were observed, with geological records showing only gradual magnetic pole wander at rates of about 50–60 km per year, insufficient for rapid physical reorientation.[66]| Predicted Date | Proponent | Key Forecasted Event | Actual Outcome |
|---|---|---|---|
| 1958–1998 | Edgar Cayce | Initiation and progression of pole shifts, earthquakes fracturing the western U.S., and submersion of parts of Japan, leading to reversed climates by century's end.[67] | No fracturing of the U.S. West Coast beyond routine seismicity; Japan remained intact without oceanic engulfment; global climate patterns persisted without polar reversal.[8] |
| By 2001 | Gordon-Michael Scallion | Submersion of U.S. East and West Coasts, creation of new Great Lakes in the Midwest, and total inundation of Japan via tsunamis and rising seas.[25] | Coasts and Japan experienced no such flooding; U.S. Midwest geography unchanged; sea levels rose globally by only ~3 mm annually, far below cataclysmic thresholds.[3] |
| By 2012 | Gordon-Michael Scallion (revised) | Extended timeline for continental reconfiguration, including emergence of new landmasses and polar melting-induced shifts.[68] | No emergence of new land or reconfiguration; Arctic ice melt occurred gradually without triggering prophesied upheavals.[3] |
