The volcano erupted again yesterday afternoon at 16:15 local time, the volcano observatory post reported. It appears it was one of the largest explosions during the volcano's current phase of activity.
Although the eruption was itself not visible due to cloud cover, the seismic signal showed a strong explosion that lasted 38 seconds and relatively "thick" ash fall occurred shortly afterwards in Batipuh and Tanahdatar districts until 17:45.
The alert level of Marapi remains unchanged at level II out of 4. Authorities recommend people to avoid a 3 km radius zone around the volcano.

- 9 Jan: 5 explosions, ash rising up to 250 m
