There is a risk that a large volcanic eruption could occur in Nicaragua at the caldera volcano known as Masaya. Elsewhere in the last week, a new volcanic eruption began at the Iwo Jima volcano. And, in Japan, the HokkaidoKomagatake volcano produced an unexpected volcanic tremor which occurred alongside changes in inclinometer readings. This video will discuss these stories and list the 47 volcanoes which are currently erupting around the planet.
