I think mt st helens last erupted in 2004
there were many warnings about mount St.Helen if they had an earthquake it would trigger the volcano to erupt causing the people to know if it will erupt or not
The first eruption was on the 18th of May, 1980.
There is always earthquakes when volcanoes erupt, so, yes.
No, Mount St. Helens last erupted in 2008. The most notable eruption of Mount St. Helens occurred on May 18, 1980, resulting in significant devastation to the surrounding area.
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.
In some cases, yes. However the most recent eruptions have produced dacite.
when did MT stromboli last erupt, and what were the effects of it.
Mt. St. Helens erupted by the pressure to make a volcano explode. Lava originates deep below the Earth's surface where it is still extremely hot, with magma at the bottom of the lava. a 5.1 earthquake triggered mt st helens to erupt
that is uncertain
