Summary Author: Marc Szeglat
The photo above shows a pyroclastic flow (foreground) with volcanic lightning during the recent eruption of Mount Sinabung, a stratovolcano on Sumatra, Indonesia. This flow traveled up to 3 mi (4.8 km) from the summit's unstable lava dome. Pyroclastic flows were observed to erupt in phases. Between these phases, activity calmed significantly -- no flows recorded for several hours. The eye-catching ash plume ascended about 2 mi (3.2 km) above the summit. Until 2010, Mount Sinabung was considered dormant. Photo taken on January 14, 2014.
