What are St Helens' eruptions like?
Mt. St. Helens has had several different styles of eruptions through its history. The types of eruptions vary from explosive to dome building. The explosive history of Mt. St. Helens is relatively well known from the May 18, 1980 eruption that captured world attention at the time. The eruption style was typical of this volcano, pyroclastic flows and lahars were both generated. The flank collapse was more than likely a result of the earthquake under the flank at the time, and is believed to have been the trigger of the eruption itself. Dome building eruptions have been the most common types of eruptions since the 1980 explosive eruption. There have been several lava domes generated since the summit eruption that generated the crater. Although they have not been witnessed in historical time, Mt. St. Helens does have a history of passive lava eruptions out of flank vents. This type of eruption although it hasn't been witnessed in a rather long time, it is believed that these types of eruptions have been just as common if not more common than the explosive eruptions we have seen in historical times.

How long was the mount st Helens eruption 1980?
Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles south of Seattle and 50 miles northeast of Portland, Oregon. The eruption was the only significant one to occur in the contiguous 48 U.S. states since the 1915 eruption of California's Lassen Peak. That eruption disrupted the lives of thousands and changed more than 200 square miles of rich forest into a grey, lifeless landscape. The eruption was triggered by a 5.1 earthquake centered beneath the mountain.
