Indonesia’s Merapi volcano erupted at 8:20 am on Friday, June 1, for about two minutes, the National Disaster Management Authority (BNPB) said.

Merapi, one of the country’s most active volcanoes, spewed a 19,600-foot column of volcanic ash to the sky during its two-minute eruption, the BNPB spokesman Sutopo Purwo Nugroho said on Twitter.

Shortly after, volcanic ash was reported falling on villages on the slopes of the volcano, including Selo. The Research and Technological Development for Geological Disaster Agency (BPPTKG), which monitors Mount Merapi, warned that volcanic ash may affect areas northwest of the volcano.

Volcanic ash also reached Ambarawa, a town nearly 40 miles north of Merapi, Detik.com reported.

Mount Merapi, which is located on Indonesia’s most densely populated island of Java, has erupted several times since May 11.

The authorities raised the status level to alert at 11 pm on May 21. An exclusion zone of 1.9-mile (3-kilometre) radius from Merapi’s peak remains in place. Credit: Homestay Merapi Indah Lestari via Storyful
