On May 2, researchers at an annual meeting of the Seismological Society of America spoke about Mount St. Helens.
Scientists describe what is going on at Mount St. Helens as refueling. Currently, the Magma is in the process of rising underground. According to Discovery, a small among of magma began to pool 2.5 to 3 miles under the volcano in 2008.
Seth Moran, a seismologist with the Cascades Volcano Observatory, looks at the GPS units and predicts when a volcanic eruption might occur again.
"This doesn't mean it's getting ready to erupt," Moran told Live Science. "The balloon has inflated, and it could stay inflated for decades. What we can say, is when it is ready to erupt, we will know."
In the early 1980s and 1990s, Moran said that earthquakes were deeper during the first quiet period. The blast of Mount St. Helens in 1980 was deadly, and it doesn’t look like another volcanic eruption is predicted for the future, according to Fox. Scientists are carefully monitoring the volcano, though, and continuing to report.
