On Mount Saint Helens, the hot lava melted the snow and ice, and it caused surges of water that eroded and this mixed with loose rock debris. This created volcanic mudflows or lahars.

Is there any connection between mount saint helens earthquake and the loma prieta earthquake?

Both Mount Saint Helens and the San Andreas Fault (source of the Loma Prieta Earthquake) sit on the Pacific Ring of Fire, but there really is little connection between the two. They both sit on the North American Plate, but San Andreas is a transform boundary with the Pacific Plate (meaning the plates move by each other), while Mount Saint Helens sits on a convergent boundary, where the Juan de Fuca plate is subducting beneath the N. American plate. A connection between the events is unlikely.


What is the significance of the Mount Saint Helens ash map in understanding the aftermath of the eruption?

The Mount Saint Helens ash map is significant in understanding the aftermath of the eruption because it shows the extent of the ash fallout and helps scientists track the movement of ash particles. This information is crucial for assessing the impact on the environment, air quality, and human health in the affected areas.

What plate boundary does mount saint helens sit on?

Mount St. Helens sits on the Cascadia Subduction Zone, which is a convergent plate boundary where the oceanic Juan de Fuca Plate is subducting beneath the North American Plate. This subduction zone is responsible for the volcanic activity in the Pacific Northwest region of the United States.
