Mount St. Helens has been emitting steam and building crater structures since its 1980 eruption, and could have another large eruption in the future. Scientists have been trying to accurately measure the magma pool beneath the mountain and the surrounding area of the Cascades. In September and October, 2004, vented magma began forming a lava dome, replacing part of the mountaintop blown off on May 18, 1980. This process continued for nearly 4 years until July, 2008.

Why do volcanologist believe that mt st Helens will erupt again?

Volcanologists believe Mt. St. Helens will erupt again because it is an active volcano with a history of explosive eruptions. Monitoring data shows ongoing volcanic activity, such as earthquakes and deformation, indicating that the volcano is still active and building pressure beneath the surface.
