~9,650 BCE meltwater pulse (Meltwater Pulse 1A) raising seas ~20 meters (65 feet), flooding coasts like the Black Sea.
Meltwater Pulse 1A occurred ~14,700–14,500 years ago (~12,700–12,500 BCE), raising seas 14–20 meters.
Geological evidence supports major underwater catastrophes during the Younger Dryas, including massive landslides and meltwater pulses, potentially linked to the subsidence of landmasses in the Atlantic, aligning with Plato’s timeline.
The Younger Dryas (circa 12,900–11,600 years ago) culminated in Meltwater Pulse 1B, a significant oceanic discharge from melting ice sheets, coinciding with Plato’s date for Atlantis’s subsidence following its war with proto-Athenians.
The myth’s “sky blazed” aligns with the Younger Dryas fire (10,800 BCE), possibly volcanic or meteoric, followed by “the sea swallowed land” as floodwaters rose (9,650 BCE), reflecting the 20-meter sea-level rise of Meltwater Pulse 1A (11,650 BP).
Then, ~9,650 BCE (11,650 years ago), ice sheets melt—Meltwater Pulse 1A—raising seas 20 meters, flooding lands like the Black Sea.
Around 9,400 BCE, Meltwater Pulse 1C caused a rapid sea level rise of several meters due to ice sheet collapse, likely devastating Atlantean coastal and island settlements.
It likely caused abrupt climate cooling, widespread fires, and megafauna extinctions, predating Meltwater Pulse 1C by over 2,000 years.
Meltwater pulse B: 7,5 meter rise, Meltwater pulse C: 6.5 meter rise.
Meltwater Pulse 1B (MWP-1B):
