Mount Merapi has once again shown significant volcanic activity on Monday (13/7) morning. The Geological Disaster Technology Research and Development Center (BPPTKG) reported that a pyroclastic avalanche flow was observed at exactly 05:09 WIB, reaching a distance of 2,000 meters.
Based on technical observation data, the pyroclastic flow moved toward the southwest and south sectors, specifically toward the upstream of the Krasak River and Boyong River. This phenomenon recorded a maximum amplitude of 19.52 millimeters with a slide duration of 109.99 seconds.
In response to the event, BPPTKG emphasized that Mount Merapi's activity status currently remains at Level III or Alert (Siaga). The public is advised not to carry out any activities within the previously established danger zone radius.
In accordance with official recommendations, the potential danger from lava avalanches and pyroclastic flows in the south to southwest sectors includes the Boyong River area up to 5 kilometers, as well as the Bedog, Krasak, and Bebeng Rivers up to a maximum distance of 7 kilometers. Meanwhile, for the southeast sector, the potential danger surrounds the Woro River up to 3 kilometers and the Gendol River up to 5 kilometers.
In addition to the threat of pyroclastic flows, authorities also warned of the potential ejection of volcanic material that could occur if an explosive eruption occurs again, with a radius reaching up to 3 kilometers from the peak. All residents are expected to remain vigilant and follow official instructions from BPPTKG to minimize disaster risks.
