One of the century's largest explosive eruptions occurred this week at a little known volcano known as Ruang. Its eruption devastated wide swaths of an existing populated island, and led to the evacuation of 12,000 people. Meanwhile, also in Indonesia, the alert level of the Awu volcano was raised from yellow to orange. The Gamalama volcano also produced a brief eruption, while in the Philippines more than 20 brief phreatomagmatic eruptions occurred from the Taal volcano. This video will discuss these stories and list the 48 volcanoes which are currently erupting around the planet.
