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_03 — Santorini/Thera Eruption and Minoan Collapse
Around 1600 BCE (revised range: 1628–1600 BCE), the volcanic island of Thera (modern Santorini) in the southern Aegean Sea experienced one of the largest volcanic eruptions in recorded human history — a VEI-7 event that
E_2_06 — Black Death, Pandemic Cycles, and Civilizational Reset
The Black Death (1347–1353 CE) was the most devastating pandemic in recorded human history. Caused by the bacterium *Yersinia pestis and transmitted primarily through flea bites from infected rats, the plague killed an e
E_2_02 — Toba Supervolcano and the 74,000 BP Genetic Bottleneck
Approximately 74,000 years ago, the Toba supervolcano on the island of Sumatra (modern Indonesia) produced the largest volcanic eruption in the last 2 million years: a VEI-8 (Volcanic Explosivity Index maximum) event tha
E_2_04 — Permian-Triassic Great Dying — The Biggest Mass Extinction
Approximately 252 million years ago, at the boundary between the Permian and Triassic periods, Earth experienced the worst mass extinction in its entire history — an event so devastating it has been called "The Great Dyi

This document examines 536 CE Climate Catastrophe, a topic within the Cataclysms and Chronology research area. Key areas of investigation include "The Worst Year to Be Alive", Historical Eyewitness Accounts, The Volcanic
E_4_03 — Paleomagnetism & Geomagnetic Excursions
Earth's magnetic field periodically undergoes dramatic excursions and full polarity reversals, with profound physical consequences including weakened radiation shielding, increased UV exposure, and ozone depletion. The L
E_4_01 — Precession of the Equinoxes and Ancient Encoded Numbers
This document examines Precession of the Equinoxes and Ancient Encoded Numbers, a topic within the Cataclysms and Chronology research area. Notable findings include: 25,920 ÷ 12 = 2,160 years** per zodiacal age. The docu
E_4_09 — Magnetic Pole Reversals and the Laschamp Event
Earth's magnetic field periodically undergoes geomagnetic reversals — events in which the north and south magnetic poles swap polarity. This has occurred at least 183 times in the last 83 million years, with the last ful
E_4_16 — Cosmogenic Isotope Dating: Beryllium-10 and Exposure Ages
Cosmogenic nuclide dating (also called cosmogenic exposure dating or terrestrial cosmogenic nuclide, TCN, dating) is a geochronological method that determines how long a rock surface has been exposed at or near Earth's s
