What was the physical destruction of Mount St Helens eruption?
Just that. A volcanic eruption
On a scale of 1 to 10 what would the St Helens eruption be?
The 1980 eruption of Mount St. Helens, a stratovolcano located in Washington state, in the United States, was a major volcanic eruption. It rated a 5 on the Volcanic Explosice Index, which rates volcanic eruptions from 1-10.
What is mt st Helens volcanic explosivity index?
Mount St. Helens had a volcanic explosivity index (VEI) of 5 during its eruption on May 18, 1980. This VEI level indicates a significant explosive eruption that released a large amount of volcanic ash and caused widespread devastation in the surrounding area.
How many people were killed mount st Helens?
57 people were killed by the volcanic eruption in Saint Helens in May 1980.
When was the worst volcanic eruption in the US?
The worst volcanic eruption in U.S. history was the eruption of Mount St. Helens that occurred on May 18, 1980. It killed 57 people and caused more than $1 billion in damage.
In Washington state mountain gave north America its largest volcanic eruption?

How do you compare the eruptions of the Hawaiian volcanoes to the 1980 eruption of Mt Saint Helens?
FALSE
Which volcanic eruption resulted in the formation of a dust cloud that traveled around the world?
mount st. helens
What type of eruption was the 1980 eruption of mt st Helens?
The 1980 eruption of Mount St. Helens was a explosive eruption caused by a lateral blast. It was triggered by a massive collapse of the volcano's north flank, releasing pressure built up within the volcano.
In 1980 this Washington state mountain gave North America it and largest volcanic eruption?
Mount St. Helens produced a large eruption in 1980. However, it was not the largest recorded eruption in North America. That title goes to the 1912 eruption of Novarupta in Alaska.
Why mount st helens volcanic eruption is unique?
Mount St. Helens' eruption in 1980 was unique due to its explosive nature and the extensive geological studies that followed. It was the first major volcanic eruption in the contiguous United States in over 60 years, providing scientists with a rare opportunity to observe and document volcanic processes in real-time. The eruption dramatically reshaped the landscape, with a massive lateral blast, ash fall, and the formation of a new volcanic dome, offering insights into volcanic hazards and eruption dynamics. Its well-documented aftermath has made it a key case study in volcanology.
What information can be found on the Mt. St. Helens eruption ash map?
The Mt. St. Helens eruption ash map shows the distribution and extent of ash fallout from the volcanic eruption. It provides information on the areas affected by the ash, including the direction and distance the ash traveled.
