Looked that up on the map. Appears to be about 100 mi E of Bellingham?
Yup.
Mt. Baker has been very quiet lately so it's one of the good stations to see worldwide stuff. It doesn't pick up alot of chatter from St. Helens.
This site has clickable seismo stations from all over the world, and it's showing up on most of them.
