A new underwater eruption at NW-Rota 1 in the Mariana Islands.
Increasing seismicity and incandescence from the rhyolite domes forming at Chaiten, Chile.
A spike in sulfur dioxide emissions from Kilauea, Hawai'i to 700 tonnes/day (up from a 2003-07 average of 150 tonnes/day).
4.5-7.5 km / 15-26,000 foot ash columns produced at Shiveluch in Kamchatka from new lava dome.
Continued dome growth and ~6 km / 26,000 foot ash columns from Nevado del Huila, Colombia.
