Volcanic Activity on Merapi
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
After weeks of activity, Merapi had appeared to be calming down when a new eruption forced fresh evacuations of nearby villages, according to news reports. On June 14, 2006, the volcano spewed a cloud of volcanic ash, covering a village several kilometers away. On June 16, news reports announced two casualties from Mount Merapi. Two men who had been assisting in the evacuation of a nearby village sought refuge in one of the emergency bunkers on the volcano’s slopes. The bunkers were designed to provide temporary shelter from clouds of hot volcanic gas, but were not designed to withstand the heat produced by the June 14 eruption.
The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA’s Terra satellite captured this image of Merapi on June 15, 2006. In this image, a thick cloud of volcanic ash blows westward away from the volcano. At the volcano’s summit is a hotspot outlined in red. This hotspot shows where the satellite sensor detected an area much hotter than its surroundings.
Mount Merapi was gearing up for an eruption in late April 2006. It erupted in early May, sending searing gas down its slopes. The volcano followed this eruption with more emissions of steam and ash in the summer of 2006.
