What can we learn from the eruption of Mount Saint Helens?
Detailed studies of the sector collapse, lateral blast, and large mudflow at Mount St. Helens led to a reassessment of volcano hazards at other sites in the United States and around the world, better preparing communities situated near such volcanoes for possible future eruptions.
What are 4 benefits of living near a volcano?
Volcanoes can provide people with many benefits such as: volcanic rock and ash provide fertile land which results in a higher crop yield for farmers. tourists are attracted to the volcano, which increases money to the local economy. geothermal energy can be harnessed, which provides cheaper electricity for locals.
What are the benefits of a volcanic eruption?
Volcanic deposits are enriched in elements such as magnesium and potassium. When volcanic rock and ash weathers, these elements are released, producing extremely fertile soils. Thin layers of ash can act as natural fertilisers, producing increased harvests in years following an eruption.

- Land formation.
- Water production.
- Fertile land.
- Geothermal energy.
- Raw materials.
Is volcano beneficial or harmful?
A long-term beneficial effect of volcanic eruption is its important role in turning the agricultural land of the host locality a lot more fertile. The ash and other materials spewed out by the volcano over the years carry minerals that break down and ultimately increase the richness of the soil.
