Study Notes
Volcano Risk Lesson Check
- Hot spots: Locations where volcanoes form away from plate boundaries are called hot spots.
- Volcanic eruptions and human casualties: People are still killed by volcanic eruptions.
- Geologic factors for volcanic eruption prediction: Geologists study ground deformation, earthquake swarms, and changes in volcano shape to predict eruptions. Animal behavior is not a factor geologists use.
- Pyroclastic flows: These flows move incredibly fast (over 100km/hr) and possess temperatures over 1000°C.
- Average volcanic eruptions: Approximately 60 volcanoes erupt annually.
- Hawaiian Islands: Examples of volcanoes formed from hot spots.
- Volcanic formation: Volcanoes form when lava and volcanic ash accumulate.
- Volcanic materials: Ash, lava, and gases erupt from a volcano.
- Volcanic danger: Even slow-moving lava is dangerous; Volcanoes release deadly gases, hot ash, and cinders causing fires and suffocation hazards.
- Earthquake data and volcano prediction: Monitoring earthquake strength and frequency, plus visual observations, help scientists predict volcanic eruptions (e.g., Mount St. Helens in 1980). Increased seismic activity, ground swelling, and vapor emissions are all signs a volcano may erupt.
