Magma rises in Mount St. Helen’s volcano

In 1980 the volcano located in Seattle, Washington tragically killed 57 people. It caused over a billion dollars in property damage. The US geological survey said that “The magma reservoir beneath Mount St. Helens has been slowly re-pressurizing since 2008” and that “it is likely that re-pressurization is caused by (the) arrival of a small amount of additional magma 4 to 8 km (2.5 to 5 miles) beneath the surface.” The USGS says that this is normal for an active volcano, and that it is not expected to erupt anytime soon.
