The super volcano Toba erupted in Sumatra approximately 75,000 years ago.

Due to the eruption, the world's human population may have dropped from over 100,000 to less than 2,000.

Deaths may have been caused by worldwide temperatures dropping five degrees C., for many years.

The Toba eruption would have spread huge clouds of ash around the world.

The Toba eruption left a hole, a caldera, which formed Lake Toba, 100 kilometres long, 60 kilometres wide.

The fine ash and sulphur dioxide blasted into the stratosphere would have reflected solar radiation back into space and stopped sunlight reaching the planet.

This would have produced a 5 degree Celcius global temperature drop.

Five degrees globally would have meant '15 degrees or so of summer cooling in the temperate to high latitudes'.


Jakartass points out that Asian and African leaders will be meeting in Jakarta and Bandung for a summit on Apr. 22 and Apr. 23, to commemorate the 50th anniversary of the Asia-Africa Conference.

"With Indonesia's volcanoes stirring in a domino effect following the movements of the tectonic plates in the past 3 months, there are fears about the 2,076-meter Mount Tangkuban Perahu, which overlooks Bandung and has been spewing out white ash, thick smoke and increased levels of hydrogen sulfide gas."
