Mount Merapi, located on the border of Central Java and the Special Region of Yogyakarta, has once again shown an increase in volcanic activity. On Monday (13/7/2026) morning, Indonesia's most active volcano was recorded releasing pyroclastic flows with a sliding distance reaching two kilometers.
According to the official report from the Geological Agency, the event occurred at 05:09 WIB. Seismograph monitoring recorded a maximum amplitude of 19.52 millimeters with an activity duration of 109.99 seconds. Volcanic material from the flow was observed moving southwest toward the upstream of Krasak River and south toward the upstream of Boyong River.
In response to this increased activity, relevant authorities have issued a stern warning to the public not to conduct any activities in the disaster-prone areas. In particular, residents are asked to stay away from the riverbeds originating from Mount Merapi to avoid the risks posed by volcanic materials.
Currently, the status of Mount Merapi remains at Alert (Level III). Authorities continue to urge residents to stay calm, increase vigilance, and monitor updates via official government channels to ensure collective safety.
