Mount Merapi, located on the border of Yogyakarta and Central Java, recorded intense volcanic activity again on Monday, July 13, 2026. According to the latest report from BPPTKG, the peak of the 2,968-meter-high mountain above sea level was observed spewing a pyroclastic flow once, reaching a travel distance of up to two kilometers toward the Boyong River.
In addition to the pyroclastic flow, instrumental monitoring recorded a high intensity of incandescent lava avalanches, totaling 19 occurrences with a similar travel distance toward the Boyong River. Visually, the weather around the mountain area was reported clear with fairly cool air temperatures ranging between 15.1 and 16.9 degrees Celsius, and air humidity reaching 78.3 percent.
Seismic data collected via the Magma BPPTKG website showed prominent seismic activity. A total of one pyroclastic flow earthquake, 31 avalanche earthquakes, and 16 hybrid earthquakes were recorded. This condition indicates that magma dynamics within the volcano are still ongoing.
As of now, authorities maintain Mount Merapi's alert status at Level III (Siaga/Alert). The public and tourists are urged to continue adhering to recommendations from volcanological authorities and stay clear of designated danger zones for mutual safety.
