PADANG - Geological Agency, Ministry of Energy and Mineral Resources (ESDM) raised the status of Mount Talang in Solok Regency, West Sumatra (West Sumatra), from Level I (Normal) to Level II (Alert).

"Based on visual observations and seismic activity until December 10, 2025, the activity level of Mount Talang has been increased from Level I (Normal) to Level II (Alert)," said Geological Agency (Plt) Geological Agency of the Ministry of Energy and Mineral Resources Lana Saria as reported by ANTARA, Wednesday, December 10.

With the rising status of the volcano, the Geological Agency issued two recommendations. First, prohibiting people around Mount Talang, visitors or tourists from approaching and spending the night around the crater of the mountain within a radius of two kilometers.

Second, he said, people around Mount Talang and visitors or tourists are asked to be aware of the potential for landslides in the South Crater area of the mountain.

The Geological Agency will continue to monitor the level of activity of Mount Talang, including informing if there are significant visual changes or seismicities.

He said, on December 10 at 02.48 WIB there was a tectonic earthquake with a magnitude of 4.7 at a depth of 10 kilometers with a distance of 18 kilometers from Solok City. After the earthquake occurred until 09.00 WIB, 227 tectonic volcanic earthquakes were recorded.

During 2025, the Geological Agency recorded four appearances of swarms, namely on April 8, July 25, September 23 and October 9. The distribution of tectonic volcanic earthquake epicenters showed that September 23 period was more clustered in the crater area than for April 8 and July 25.

Likewise, the tectonic volcanic earthquake swarm depth for the period September 23 is shallower than the period from April 8 and July 25, 2025.

The emergence of this earthquake indicates the migration or displacement of magma from a deep magma pocket towards the surface.

Meanwhile, the emergence of tectonic volcanic swarm phenomena is an indicator of instability in volcanic conditions that are sometimes followed by eruptions.
