Volcanic activity at Mount Merapi, located on the border of Yogyakarta and Central Java, was observed to be active again on Wednesday, July 8, 2026. The Geological Disaster Technology Research and Development Center (BPPTKG) reported four occurrences of incandescent lava avalanches from the volcano's peak.
Based on observational data, the incandescent lava material traveled a maximum distance of up to 1.9 kilometers. The flows were predominantly directed toward the Sat River and Putih River channels. Visually, the volcano was clearly visible with white crater smoke billowing up to 25 meters above the peak.
In addition to the lava avalanches, monitoring instruments recorded fairly intensive seismic activity. A total of 24 rockfall earthquakes and 15 multi-phase or hybrid earthquakes were recorded during the observation period. Weather conditions around the peak area were reported as clear, with cool air temperatures reaching 14.5 degrees Celsius and air humidity at 89.6 percent.
Given the continuing fluctuation in volcanic activity, authorities have maintained Mount Merapi's status at Level III or Standby. The public and hikers are urged to adhere to the danger zone recommendations set by the government for safety around the 2,968-meter-high volcano.
