I am reliably informed that Mount Saint Helens has erupted. I'll keep you posted with the latest from Herculaneum.
UPDATE: KIRO-TV News reports: 'A large plume of steam is being emitted this afternoon from the crater of Mount Saint Helens. The plume was accompanied by an earthquake of about 2-point-zero magnitude. ...' Read the story at the link.
