E_3_07 — Late Bronze Age Collapse

The Late Bronze Age Collapse (c. 1200–1150 BCE) was one of the most dramatic civilizational catastrophes in human history — a cascade of destructions, abandonments, and systemic failures that ended the interconnected pal

E_3_04 — Doggerland and Sundaland — Drowned Continental Shelves

Doggerland and Sundaland represent two of the most significant landmasses lost to post-glacial sea level rise, together encompassing hundreds of thousands of square kilometers of habitable terrain that was progressively

E_3_11 — Earthquake Archaeology and Seismic Catastrophes

Archaeoseismology — the study of past earthquakes using archaeological evidence — reveals that seismic catastrophes have repeatedly destroyed, reshaped, and sometimes permanently ended ancient urban centers and entire ci

E_3_08 — Dansgaard-Oeschger Events and Abrupt Climate Change

Dansgaard-Oeschger (DO) events are rapid climate oscillations during the last glacial period (c. 115,000–11,700 years ago) characterized by abrupt warming of 5–16°C in Greenland within decades — among the most dramatic a

E_3_13 — Storegga Slide: Mega-Tsunami and Mesolithic Europe

The Storegga Slide (Norwegian: Storegga-raset; Store = "great," egga = "edge") — a series of submarine landslides on the continental slope off western Norway at approximately 64°N — constitutes one of the largest known m

E_3_16 — Urban Fire and Civilizational Destruction: Rome, London, Chicago

Urban fires have been among the most recurrent and devastating agents of civilizational destruction throughout recorded history, repeatedly leveling major cities and reshaping their physical layouts, governance structure

E_3_03 — Ice Age Civilizations — Evidence for Complexity During the Last Glacial Maximum

The Last Glacial Maximum (LGM, ~26,500-19,000 BP) — when ice sheets covered ~32% of the global land surface and sea levels dropped ~120 meters below present — was not a period of human stagnation but of remarkable cultur

E_3_14 — Missoula Floods: Channeled Scablands and Catastrophism Vindicated

The Missoula Floods (also called the Spokane Floods or Bretz Floods) were a series of catastrophic megafloods — among the largest known floods in Earth's history — that swept across the inland Pacific Northwest of the Un

E_3_09 — Messinian Salinity Crisis

The Messinian Salinity Crisis (MSC) — approximately 5.96–5.33 million years ago (late Miocene) — was one of the most dramatic geological events in the Cenozoic: the near-complete desiccation (drying up) of the Mediterran

E_2_17 — Campanian Ignimbrite: 40,000 BP European Super-Eruption

The Campanian Ignimbrite (CI) eruption — also known as the CI super-eruption — was the largest volcanic event in the Mediterranean region during the past 200,000 years and one of the largest explosive eruptions in the La

E_2_07 — The 4.2 Kiloyear Event — Bronze Age Climate Catastrophe

The 4.2 kiloyear event (~2200 BCE) was a severe, century-scale aridification episode that constitutes one of the most significant abrupt climate changes of the Holocene. Identified through speleothem, marine sediment, an

E_2_05 — Late Antiquity Little Ice Age (536–660 CE) and the Fall of Antiquity

The period 536–660 CE represents one of the most catastrophic environmental and civilizational crises in recorded human history, now termed the Late Antiquity Little Ice Age (LALIA). It began in 536 CE — described by his

E_2_13 — Paleocene-Eocene Thermal Maximum

The Paleocene-Eocene Thermal Maximum (PETM) — approximately 55.8 million years ago — was the most extreme rapid warming event of the past 66 million years and is widely studied as a deep-time analog for modern anthropoge
