What is mt st Helens volcanic explosivity index?
The famous eruption of Mount st Helens in 1980 was a VEI-5.
What does vei represent?
Volcanic Explosivity INdex (VEI)
What would you use to measure the magnitude of an volcano?
Volcanic Explosivity Index
What is the Volcanic Explosivity Index of Eldfell?
there isn't one
What is the Volcano Explosivity Index?
The VEI (Volcano Explosivity Index) rates volcanic eruptions based on the volume of ejected material, the height of the eruption plume, and the time duration of the event. The scale runs from 0 (low volume, non-explosive lava flow) to 8 (mega-colossal volcanic explosion, accompanied by seismic events and/or tsunamis). E.g. Mount St. Helens, 1980, had a VEI of 5. Mount Mazama (an exploded volcano that now forms Crater Lake) erupting around 5600 BC, had a VEI of 7.
Was mt pinatubo a category 5?
No. "Category 5" is a rating on a system, used for hurricanes. Mount Pinatubo is a volcano. Volcanoes do not have a rating system but eruptions do: Volcanic Explosivity Index, which ranges from VEI 0 to VEI 8. On this scale the 1991 eruption of Mount Pinatubo was a VEI 6.
What the 1951 eruption of Mount Lamington register on the Richter Scale?
Volcanic eruptions don't go by the Richter Scale.. perhaps you are thinking of the VEI (Volcanic Explosivity Index) Scale? If so, the VEI of Mt. Lamington was a level 5.
What was the magnitude of the mt st Helens eruption in 1980?
Wikipedia lists its explosive index as 5. Read below for more details about the Volcanic Explosivity Index.
What type of scale is used to measure a volcano?
Volcanoes are measured on the volcano explosivity index. See the link below for more information.
Is explosivity a chemical property?
Explosivity is a chemical property.
What was the Richter scale for the Kobe earthquake?
It did not have a Richter scale rating. The Richter scale is used to rate earthquakes, not volcanic eruptions. Volcanic eruptions are rated on the Volcanic Explosivity Index. The 1991 eruption of Mount Pinatubo was a VEI 6, described as a colossal eruption.
What is the magnitude of nevado del ruiz volcano?
The Richter scale is applied to earthquakes, not volcanoes. The 1985 eruption was a VEI 3 on the Volcanic Explosivity Index.
