Tierra Blanca Joven eruption
Catastrophic volcanic eruption of Lake Ilopango in El Salvador
The Tierra Blanca Joven eruption of Lake Ilopango was the largest volcanic eruption in El Salvador during historic times, and one of the largest volcanic events on Earth in the past 7,000 years, registering at 6 on the Volcanic explosivity index (VEI), and dating back to the mid 5th century A.D. The eruption produced between 37–82 km3 (8.9–19.7 cu mi) of ejecta (dense-rock equivalent).[2][3][4] The date of the eruption has been constrained within 429–433 CE by identifying its signature volcanic ash in precision-dated ice cores sampled from Greenland, thus eliminating it as the cause of extreme weather events of 535–536.[2]
