I’m still playing catch-up after my week in the desert, so I’ve seen a lot of articles I’ve wanted to mention … but a certain other volcano has taken up a lot of my time. However, I will attempt to make amends for that now.
By the way, would you believe Ubehebe Crater was closed? How do they close a volcano, anyway? However, I did get a great snap of a welded tuff on the road outside of Shoshone, CA.
A strongly welded tuff near Shoshone, CA. The dark interior is remelted volcanic ash/tephra surrounded by less welded pink tuff with abundant pumice clasts. Denison student David Sisak is on the left for scale.
I ran across some impressive holiday snaps taken of one of the recent large eruptions at Soufriere Hills on Montserrat. On one hand, all I could think was “I wish I was on that flight” but on the other hand I was wondering how frightening that might be. I think the first hand might win that argument.
Need a gift for the volcanophile who has everything? How about the new deck of cards being offered by the Alaska Division of Geological and Geophysical Survey? It features all 52 of Alaska’s potentially active volcanoes. Yes, indeed, I’ll see your Okmok.
Melimoyu in Chile continues to show signs that it might be rumbling back to life as well. The seismicity in the area has been determined to be coming from Melimoyu according to the SERNAGEOMIN of Chile, all between 3 and 22 km depth (which is quite a range). The earthquakes were coming in at 7-8/hr on March 17 and 18, but since then have returned to only 2/hr. That being said, the volcano will be under 24-hour surveillance starting immediately.
A couple of new images from the NASA Earth Observatory: (1) A view of the current activity at Kilauea – now there is a basaltic volcano that Eyjafjallajokull has to look up to; (2) A view of the “quiescent” Etna that I’m sure Boris will appreciate – the craters definitely stand out in the snow cover.
