Mount Merapi eruption 2018: people ordered to stay away as Indonesia’s most active volcano rumbles
A series of eruptions at Mount Merapi in 2010 killed almost 350 people and authorities are taking no chances
Indonesian authorities raised the alert for the volatile Mount Merapi volcano on the densely populated island of Java and ordered people within 3 kilometres (2 miles) to evacuate.
Merapi has erupted four times since Monday, sending out a 3,500 metre (11,483 feet) column of volcanic material and dusting the surrounding region in ash.
Sutopo Purwo Nugroho, the national disaster mitigation agency’s spokesman, said some 660 people living within the exclusion zone have evacuated since early Tuesday.
Indonesia’s geological agency raised Merapi’s alert from normal to “beware” because of its increased activity.
The disaster agency described Merapi’s eruptions as phreatic, which means magma heats up groundwater and vapour is released under pressure.
This month, the airport in Yogyakarta, the closest city to the volcano, was briefly shut down because of the eruptions.
