The Lake Malawi Sediment Chronometer and the Toba Super Eruption
One of the largest volcanic eruptions in earth’s history, the Toba super eruption has been a special interest to anthropologists and climatologists because of its potential impacts on past human populations.   I have explored the implications of the Toba eruption on human history in previous posts (See: The Toba Super Eruption: A Global Catastrophe that...

The Toba Super Eruption, Polar Ice Cores, and Climate Change
I recently discussed how the catastrophic Toba super-eruption in Indonesia is a serious challenge to the young-earth model of earth's history (The Toba Super Eruption: A Global Catastrophe that Creationists Ignore). Briefly, Â I explained that the Toba volcano caldera produced the largest eruption in the past 100,000 years releasing an estimated 2800 cubic kilometers of... Continue Reading →
The Toba Super-Eruption: A Global Catastrophe that Young-Earth Creationists Ignore
Sudden catastrophic events are not unknown in earth’s history. Large craters are evidence of past cosmic impacts and widespread layers of volcanic ash are a testimony to massive volcanic eruptions. But when did these catastrophes occur and could they have influenced human history? Standard geological models place the largest catastrophic events far in the past. ... Continue Reading →
