Sumatra's Mount Talang, one of three volcanoes made active by a massive quake on Sept. 12.
The powerful Indonesian earthquake that struck Sumatra last week, and subsequent strong aftershocks, caused an increase in activity within three nearby volcanoes.
The country’s chief vulcanologist, Saut Simatupang, told Reuters that an increase in the flow of magma was detected at Kaba, Talang and Dempo for days following the quake.
Mount Talang, which lies just 19 miles (30 km) from Padang, the city nearest to the epicenter, recorded nearly 40 times the normal number of volcanic tremors a day after the quake, Simatupang said.
Volcanic tremors created by the surge in magma have subsided in conjunction with the dwindling number of aftershocks.
