The Geological Disaster Technology Research and Development Center (BPPTKG) reported an increase in activity at Mount Merapi, located on the border of Yogyakarta and Central Java, on Tuesday, July 7, 2026. Based on recent monitoring, the 2,968-meter-high volcano launched incandescent lava avalanches 11 times.
The volcanic material was observed moving toward the western sector, specifically into the Sat River and Putih River channels, with a runout distance reaching two kilometers. Visually, weather conditions around the peak area were reported to be clear to cloudy, allowing for the observation of white crater smoke reaching 15 meters above the summit.
Seismic data recorded on the Magma Indonesia website indicates a fairly high intensity of seismic activity. A total of 28 avalanche earthquakes and 18 hybrid earthquakes were recorded during the observation period. This condition reflects the ongoing dynamics of magma activity within the mountain.
The public is urged to remain calm yet vigilant and to follow instructions from the relevant authorities. Given that Mount Merapi is currently still at Level III (Alert) status, hiking activities and any operations in high-risk hazard zones remain prohibited for the safety of residents and visitors around Merapi's slopes.
