VANCOUVER, WA - Scientists have began installing super-sensitive seismic monitors around Mount St. Helens as part of a two-year study of the magma underneath the volcano.
The U.S. Geological Survey study aims to look at how molten underground rock connects to volcanoes. They say the information could help in forecasting eruptions. The study will also measure fluctuations in the earth's magnetic field along with seismic signals created by setting of explosive charges.
Cascades Volcano Observatory seismologist Seth Moran says in the future the study could expand to other volcanoes. He says he'd like to compare the magma systems of volcanoes in Washington and Oregon.
