Sarychev Peak: Before and after

The NASA Earth Observatory has posted some excellent images of Matua Island in the Kurils that show the before and after of the Sarychev Peak eruption of June 2009. There are some impressive changes … so lets see if you can spot them! Post your comments on whats changed and why and I’ll chime in…

Redoubt steaming in early 2009. Image courtesy of Calvin Hall. It has been a while since we spoke of Redoubt, but now it seems the reason why might be that the eruption is ending. AVO lowered the Alert Level at Redoubt to Yellow from Orange, indicating that they believe the volcano is less likely to…

Shiveluch volano in Russia. Just like last summer seemed like a busy time for the Aleutians (Cleveland, Okmok and Kasatochi), this summer could be dubbed the “summer of Kamchatka-Kurils” (alright, it isn’t that catchy, sorry). The biggest news was/is, of course, the sizeable eruption from Sarychev Peak in the Kuril Islands, but not to be…

Drilling into active magma

Drilling in Iceland lead by geologists from UC Davis hit magma this week. Image courtesy of Peter Schiffman, UC Davis. Quick props to my officemate here at UC Davis, Naomi Marks, who happened to be part of a team (with UC Davis geology faculty Peter Schiffman and Robert Zierenberg) that drilled into active rhyolite magma…

Tuesday Tidbits

A few quick news bits … and thanks for the questions so far. Keep ‘em coming! Tungurahua, Ecuador erupting in 2006. Ash fall from Tungurahua (in spanish) in Ecuador is affecting the farm towns around the volcano. Farmers in Manzano, a village nearby, fear the ash is significant enough to damage their crops.

Send me your volcano questions

I’m buried knee-deep in lab work this week, so I don’t know how much internet scouring I will be able to do for new news, however, I should have time for a mailbag column. So, do you have a burning (no pun intended) volcano question you want answered? Email the question(s) to me and I…

Friday Flotsam

Some volcano news before the weekend: The Barujari vent at Mt. Rinjani erupting in May 2009. Barujari, the small basaltic volcano located in the crater at Mt. Rinjani, is “spewing 200-meter-high lava“, at least according to recent reports. It is unclear if the eruption is, in fact, a fountain or merely strombolian activity throwing incandescent…
