Warning! Mount Dempo Erupts Again This Morning (Sunday, January 12, 2025)

Mount Dempo in South Sumatra erupted again on Sunday, January 12, 2025, at 6:05 WIB (Western Indonesian Time). This was only the mountain's second eruption in the past week.

According to eruption information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG) via the MAGMA Indonesia application, the ash column reached a height of 20 meters above the peak (3,193 meters above sea level).

The ash column was observed to be white with low intensity, drifting north. The eruption was recorded on a seismograph with a maximum amplitude of 25 millimeters and a duration of 24 seconds.

According to the MAGMA Indonesia volcano activity report, Mount Dempo's alert level is at Level II (Alert). Observations of seismic activity from 00:00 to 23:59 WIB on January 12, 2025, showed one puffing event with an amplitude of 10 millimeters and a duration of 8 seconds. There was also one continuous tremor with an amplitude of 0.5-1 millimeter, predominantly 0.5 millimeters.

The PVMBG advises the public and visitors/tourists not to approach or stay overnight (camping) within a 1-kilometer radius of the Marapi-Mount Dempo crater's activity center, and to avoid the crater's opening towards the north sector up to 2 kilometers. This is due to the crater being the center of eruptions and volcanic gases that can be hazardous to life.

In 2025, MAGMA Indonesia has recorded 253 volcanic eruptions/eruptions across Indonesia. Mount Semeru in East Java had the most eruptions (161 times), while Mount Dempo erupted once.
