I'll be giving a talk this afternoon here at Denison on rhyolite generation, so I might be a little brief this morning.
Undated image of Mayon in the Philippines.
- The province of Albay in the Philippines is on alert for both a typhoon and a volcano (that country seems to be hit with that 300,000 may need to be ready to evacuate if the volcano continues to show signs that it might erupt - in fact, Mayon is producing ash as of this morning, albeit only one minor ash explosion.
- Lava flows from Kilauea are drawing crowds as they inundate a road in Kalapana. There is a nice video link to the gawkers watching the lava ooze its way across the access road (very very slowly). The lava flow seemed to have stopped after crossing the road, but now it appears to be continuing to head to the sea.
- Lastly, the NASA Earth Observatory has posted a couple new images worth a peak: one is of the current plume at Chaiten in Chile, the other of the activity at Shiveluch in Russia.
I'll put on you on the spot and ask, "How do you generate rhyolite Erik?"
While we have to wait for things to develop further at Mayon, we can now take a look at the SoufriÃ¨re Hills volcano (Montserrat) in real time: the MVO (www.montserratvolcanoobservatory.info) is providing images from a monitoring camera. As of 17.58 h (time indicated in image frame) there's quite some pyroclastic flow activity visible.
Wow Boris, how have I missed this updated MVO website until now? I think they have set the bar for Volcano Observatory sites - lots of info, webcams and well organized. Kudos to the MVO folks.

That undated pic of Mayon: it looks very like the 1993 lava flow down the SE flank in the middle of the image, which would give an upper age limit for its date
Thoroughly interesting looking blog. My eldest son is developing a keen interest in all things related to volcanoes. This blog may be just the thing to stimulate him further.
