Mt. St. Helens' May 18th, 1980 eruption changed the landscape drastically and jsut in a few moments at most. The eruption itself was not a typical eruption that would have had a vertical eruptive column followed by a collapsing pyroclastic surge. Instead it was a northen directed blast that focused from a bulge on the north flank of the volcano. This gave the pyroclastic Flow a significantly higher amount of energy that was directed in one direction, while a pyroclastic surge would have gone vertical and than only had gravity to bring it down the slopes of the volcano. The pyroclastic flow generated by the lateral blast let the eruption get roughly 13-15 Km from the base of the volcano. The ecosystem itself was decimated by teh volcano, nothing could survive the intense heat as well as the blast wave itself. All trees were uprooted and completely destroyed. It took many years for the wildlife to flly get a foothold in the region again, and some parts of the old Spirit Lake are still closed to the public over thirty years later.
Main Points:
- Trees and wildlife were extinguished in the effected area.
- Damage extended well outside of the predicted area for the volcano.
- Full recovery of wildlife took on order of ten years.
- Spirit lake ecosystem completely decimated.
- Refer to CVO website for further ecological effects.

How did mount st helens effect humans?
The eruption of Mount St. Helens on May 18, 1980, had a significant impact on humans, including causing 57 direct fatalities and extensive damage to infrastructure, forests, and wildlife. The ashfall from the eruption also affected air quality, agriculture, and transportation in the surrounding areas. Additionally, the eruption led to changes in land use policies and increased monitoring of volcanic activity to enhance public safety.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
How did Krakatoa affect the geosphere?
The eruption of Krakatoa in 1883 caused widespread destruction in the geosphere, with ash reaching the stratosphere and impacting global climate. The volcanic eruption also triggered tsunamis that affected the surrounding areas. The explosion was one of the most powerful in recorded history and caused significant changes in the landscape of the region.
How can the composition of magma affect the way volcano erupts?

Does the shape of the volcano affect the directions the eruption travels?
i dont think so. So the answer is probably no.......

Does soda affect the eruption of a baking soda volcano?
Yes, soda can affect the eruption of a baking soda volcano because the reaction between the baking soda and vinegar (or other acidic liquid) produces carbon dioxide gas, creating the fizzing eruption. The type of liquid used can impact the rate and intensity of the reaction.
