The volcano Merapi in central Java had a strong eruption in Oct./Nov. 2010 (VEI=4), which left more than 350 people dead and three hundred thousand lost their homes and livelihood.

Merapi is one of the most active and most dangerous volcanoes in Indonesia, mainly due to the dense population that includes Yogyakarta city to the south of it. Pyroclastic flows and lahars accompanying growth and collapse of the steep-sided active summit lava dome have devastated cultivated lands on the western-to-southern flanks and caused many fatalities during historical time.
