Lake Toba which is found today in the collapsed caldera crater of Toba volcano in
Sumatra. This lake is 100km long and 30km wide and was formed after an
estimated 2800 cubit kilometers of ash was thrown into the atmosphere. For
comparison, Mt. St Helens in Washington State only spewed 1 cubit kilometer of
ash.
the largest known volcanic eruption of the last
200 years, that of Tambora on Sumbawa
Island, Indonesia, occurred in 1815. Enormous
volumes of pyroclastic flow followed by
caldera collapse created an up to 10m wall of
water that devastated the Indonesian
shoreline. While the eruption (and aftermath)
of Tambora has been credited with the loss of
more than 71,000 lives, as many as 10,000 of
those are attributed to the resulting tsunami.
Death from the ash cloud
Most deaths are not directly from the eruption
but rather The aftermath:
