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 quiet mountain in
Washington provided detailed observations on
the mechanics of highly explosive eruptions.
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.
