It's the last week of classes and it's also AGU (which I will be missing for the first time in 5 years). If you happen to be at the big meeting in SF and hear something you think we'd like to hear, feel free to drop me a line or leave a comment so we can live vicariously through you.

Mayon continues to belch ash, leading PHIVOLC to continue to have concern for a larger eruption of the Philippine volcano. The activity has increased to the point where 20,000-30,000 of villagers were ordered to evacuate on Monday. Mayon experienced at least 4 explosions that sent ash and incandescent material to the northwest and over the last 24 hours, the volcano has emitted 535 tonnes of SO2. This comes with increased seismicity and 5 mm / 1 inch of inflation (although in what period this inflation has occurred is unclear) as well. The 7-km exclusion zone remains in effect with Mayon on Yellow status.
