Mount St Helens puts on another good show overnight

The U.S. Geological Survey and Pacific Northwest Seismograph Network are reporting that the "latest estimate of the volume of the uplifted area and new lava dome from detailed analysis of aerial photographs taken on 4 November is about 20 million cubic meters (26 million cubic yards)" and that the "...new uplift and lava dome is now more than 25% of the volume of the lava dome that grew in the crater between 1980 and 1986"!

The mountain put on another good but relatively quiet show on the Volcanocam last night, with several distinct glows visible throughout the night. The brightest and most persistent of the glows still corresponds to the large area of glowing lava indicated in the recent photos from the USGS that were posted here last night.
