Mount Merapi once again showed quite intense volcanic activity on Monday, July 6, 2026. The Geological Disaster Technology Research and Development Center (BPPTKG) recorded eight instances of incandescent lava avalanches sliding from the mountain's peak, with a maximum sliding distance of up to two kilometers. The direction of these avalanches was predominantly toward the Sat River and Putih River sectors.
Based on visual observation reports, the condition of Mount Merapi was clearly observed with clear weather around the summit area. No crater smoke was observed during this observation period, while the air temperature around the mountain area was recorded at 16.4 degrees Celsius with a humidity level reaching 97.6 percent.
In addition to visual activity, seismic instruments also recorded quite active seismic activity. BPPTKG data showed 36 avalanche earthquakes, eight multi-phase (hybrid) earthquakes, and one shallow volcanic earthquake. This seismic activity is an important indicator in monitoring the stability of the 2,968-meter-high mountain above sea level.
To date, geological authorities have emphasized that the status of Mount Merapi remains at Level III or Alert (Siaga). The public and tourists are urged to continue complying with official recommendations from the authorities to avoid risks arising from ongoing volcanic activity.
