creating a long process that eventually resulting in the formation of volcanoes.

1 Introduction Since the eruption in 1980, the area around Mount St. Helens has rebounded in ways that were somewhat unexpected, with recovery coming not only from the surrounding area, but from within the barren expanse that remained after the eruption. While not the first eruption overall, this eruption was the first to occur on the U.S mainland in a time when modern scientific monitoring could track the events associated with it. Smaller earthquakes in March of 1980 eventually led to the…

boundaries. A convergent boundary is when two tectonic plates collide into each other, forming mountains. The transform boundaries form mountains when they slide into one another. Hotspots are formed when the magma is forced up to the Earth's surface. Before Mount St. Helens erupted, there was an earthquake with a magnitude of 5.1 that struck the north face of the mountain causing a massive landslide (largest debris avalanche on Earth in recorded history). That landside removed Mount St.…

been closely monitoring a steaming, trembling snow-capped mountain near Vancouver, Washington. Mount St. Helens had not erupted in over 100 years. But two months earlier, an earthquake had jolted it to life. Homes were evacuated and roads were closed as hundreds of explosive blasts of steam burst from the volcano and earthquakes shook the area. Scientists knew that pressure was building up inside the mountain. They could see that the north side had grown outward almost 450 feet (140 meters).…
