Volcanic Places in the USA

Listed below are two places in the United States that are
considered "active" volcanic areas.

Mount St Helens

On May 18, 1980, after a long period of rest, this quietmountain in Washington provided detailed observations
on the mechanics of highly explosive eruptions.

Long Valley

This field seismometer measures earthquakes associated with subsurface volcanic forces and may help to predict future events. It sits on a plateau known as the "Volcanic Tableland" formed by a major eruption 600,000 years ago.
