This Week in Volcano News; Taal Erupts, Earthquake Swarm at Mauna Loa |
|
There are currently 49 volcanoes that are erupting, 3 of which are in Antarctica. During the last week, the summit area of Mauna Loa was closed off due to elevated seismic activity. Meanwhile in the Philippines, the Taal volcano produced a small phreatic eruption. And, also in the Philippines, the Bulusan volcano has an elevated risk of producing another eruption in the short term due to a swarm of earthquakes the volcano just produced. This video will discuss these volcano related news stories, as told and analyzed by a volcanologist.
I would like to give a special thanks to A. Eschenbacher for sending me a group of Erebus crystals and volcanic rocks from Mount Erebus, in addition to allowing me to use several photos he took while there!
