Erupsi Gunung Merapi (ANTARA)

SLEMAN - Mount Merapi on the border of Central Java and the Special Region of Yogyakarta spewed 60 lava avalanches and 121 avalanches in the last 24 hours until Monday, April 28 in the morning.

"60 lava avalanches were observed to the southwest, namely Bebeng River, Krasak River, and White River with a maximum sliding distance of 1,900 meters," said Head of the Geological Disaster Technology Research and Development Center (BPPTKG) Agus Budi Santoso in his statement.

In the monitoring period on Sunday (27/4/2025) until early this morning, it was recorded that Mount Merapi experienced 121 avalanches with an amplitude of 2 to 19 millimeters and a duration of 37.81 to 184.3 seconds, as well as 125 times a hybrid / multi-phase earthquake.

Visually, the weather around Mount Merapi was observed to be sunny to cloudy. Weak pressure crater smoke in white was observed with a thin intensity rising as high as 10 to 50 meters above the peak.

Until now, the status of Mount Merapi is still at level III or on standby.

The BPPTKG stated that the potential danger includes lava avalanches and hot clouds in the south sector, especially in the Boyong River as far as a maximum of 5 kilometers, as well as the Bedog, Krasak, and Bebeng rivers up to 7 kilometers. In the southeast sector, the potential danger covers the Woro River as far as 3 kilometers, and the Gendol River as far as 5 kilometers.

" Monitoring data shows the supply of magma is still ongoing, which can trigger hot clouds of avalanches in potential hazard areas," he continued.

The public is advised not to carry out any activities within potential hazard areas and increase vigilance, especially against the dangers of lava and hot clouds falling, especially when it rains in the Mount Merapi area.

In addition, residents are also asked to anticipate the impact of volcanic ash in the event of an eruption of Mount Merapi.
