Study Notes

Volcano Risk Lesson Check

Locations of volcanoes far from plate boundaries are called hot spots.
Volcanic eruptions can cause casualties.
Geologists study ground deformation, earthquake swarms, and changes in volcano shape to predict eruptions. Animal behavior is not a factor.
Pyroclastic flows move very fast (over 100 km/hr) and are extremely hot (over 1000°C).
On average, around 60 volcanoes erupt each year.
Hawaiian Islands are associated with hot spots.
A volcano is formed from layers of lava and volcanic ash.
Eruptions release ash, lava, and gases.
Volcanic eruptions have hazards including deadly gases, hot ash and cinders that can cause fires and bury/suffocate.
Scientists monitor volcanic activity by tracking earthquakes, ground swelling/changes in shape, and presence of gases to predict potential eruptions. Examples include data from Mount St. Helens in 1980.
