Yogyakarta (MidLand) – Mount Merapi, on the border of Central Java and the Yogyakarta Special Region (DIY), launched lava avalanches 15 times on Thursday with a maximum flow distance of 1.8 kilometers.
BPPTKG Yogyakarta head Agus Budi Santoso, in a statement in Yogyakarta on Thursday, explained that based on observations from 00:00 to 06:00 WIB, the lava avalanche rolled towards the Bebeng River.
“We observed 15 lava avalanches in the southwest (Kali Bebeng) with a maximum sliding distance of 1,800 meters,” he said.
During the observation period, 21 avalanche earthquakes with an amplitude of 3-34 mm for 69.84-180.4 seconds and two multiphase earthquakes with an amplitude of 3-5 mm for 5 seconds also occurred on Mount Merapi. .8-5.92 seconds.
During the observation period on Wednesday (1/5) between 00:00 and 24:00 WIB, Mount Merapi was also recorded six times launching lava avalanches towards the Bebeng River with a maximum flow distance of 1,700 meters.
In the BPPTKG report for the period 19-25 April 2024, it was observed that the morphology of the southwest dome of Mount Merapi changed due to lava avalanche activity, while the morphology of the central dome was relatively constant.
Based on the analysis of aerial photos dated March 30, 2024, the volume of the southwest dome was measured at 2,054,600 cubic meters and that of the central dome at 2,358,200 cubic meters.
Agus said BPPTKG currently still maintains Mount Merapi’s status at Level III or Alert.
To anticipate the potential danger of the Mount Merapi eruption, BPPTKG urges the public not to carry out any activities in potentially dangerous areas.
Falling lava and hot clouds from Mount Merapi could impact areas in the south-southwest sector which include the Boyong River (a maximum distance of five kilometers) and the Bedog, Krasak and Bebeng rivers (a maximum distance of seven kilometers ).
The southeastern sector covers the Woro River for up to three kilometers and the Gendol River for five kilometers. Meanwhile, when an explosive eruption occurs, volcanic material can reach a radius of three kilometers from the summit.
