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 he took while there!

Key for volcano color codes shown in this video (this is only if they do not represent official alert levels from local government / volcanological agencies):
GREEN – Normal volcanic activity, very low chance of an eruption.
LIGHT YELLOW – Minor increase in levels of volcanic activity, such as increased earthquakes, very low chance of an eruption, but higher than with green.
BRIGHT YELLOW – Notable increase in levels of volcanic activity, potential changes at the volcano, increased risk of an eruption.
ORANGE – High volcanic unrest, this often means a volcano is about to erupt or has a greatly increased likelihood of erupting in the short to mid term future (seconds to weeks). However, an eruption occurring is not a certainty as this alert level.
RED – The volcano is erupting.
