Indonesia's Mount Merapi is the nation's second most active volcano and has great spiritual significance for those living on its fertile slopes.
Merapi, which means "Mountain of Fire", typically has small eruptions every two to three years, and larger ones about once every 10 to 15 years.
Its last major eruption was in 1994, when 66 people were killed. It also spewed smoke and lava in 2001 but no major eruption followed.
Located about 400 kilometres (250 miles) east of Jakarta in Central Java province, it looms over the Kedu plain and provides rich, bountiful soils for the thousands of people living around it.
