MERAPI!

Der Spiegel report:

A rough estimate indicates that there is three times more magma than what was ejected by the Indonesian volcano Tambora in 1815 – the biggest eruption in the last 10,000 years, which led to a cooling of the climate globally.

Word of a ‘mega-eruption’ is making the rounds among scientists. But apparently they are avoiding the use of the word to avoid being labelled preachers of disasters.

Tambora


"the bright sun was extinguish'd... morn came and went--and came, and brought no day"

-Darkness by George Gordon, Lord Byron The Eruption
On April 10, 1815, a series of eruptions began, culminating to the largest eruption in recorded history. The eruption lasted several days. It blew a chunk off of the mountain almost a mile wide. The volcanic column, after flying 40 km into the sky, returned to the ground, creating a huge pyroclastic flow of ash, pumice, and debris. The pyroclastic flow alone killed more than 10,000 people in its path. The ash that fell from Tambora travelled as far as 1300 km (800 miles) away.
When the pyroclastic flow reached the ocean, the debris created such a large displacement of water that tsunamis as high as 5 meters emanated out from the island. These tsunamis caused flooding, devastation, and death on many of the other Indonesian islands.
After the eruption was over, and estimated 100-150 cubic kilometers of ash and debris were said to have been ejected from the mountain.
