No one knows when a volcano is going to become active again. The Cascade Range is one of the most active volcanic areas in the world, and new activity is to be expected. The Three Sisters area in central Oregon is perhaps the next most likely area to see volcanic activity, as it has been swelling several centimeters per year for about 10 years now. Mt. St. Helen's is still erupting, although quietly, in a dome-building eruption, but that could change at any time. Mt. Hood has not given any signs that it is going to become active soon, but it is still considered "active" as the last activity was only a few hundred years ago.

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. This suggests that another eruption is possible in the future.
