Flashcards

What are volcanoes called that form far from plate boundaries?

Volcanoes that form far from plate boundaries are called hotspots.

Can volcanic eruptions be deadly?

Volcanic eruptions can be deadly and cause significant damage to property and the environment.

What do geologists NOT use to predict volcanic eruptions?

Geologists look for signs like ground deformation, earthquake swarms, and changes in the volcano's shape to predict eruptions, but not animal behavior.

What is a pyroclastic flow?

A pyroclastic flow is a rapidly moving, superheated cloud of ash, gas, and rock fragments, reaching speeds over 100 km/hr and temperatures exceeding 1,000°C.

What type of volcanic feature formed the Hawaiian Islands?

The Hawaiian Islands are a chain of volcanoes formed by a hotspot, a stationary location in the Earth's mantle where magma rises to the surface.

How does a volcano form?

A volcano typically forms a mountain when layers of lava and volcanic ash erupt and build up over time.

What are the main components of a volcanic eruption?

Volcanic eruptions release a mixture of ash, lava, and gases, creating a powerful and dangerous event

Why are volcanoes dangerous even if lava moves slowly?

Volcanic eruptions can be dangerous even if the lava moves slowly enough for people to escape because volcanoes also release deadly gases, hot ash and cinders that can cause fires, bury buildings and suffocate people.

How do scientists monitor volcanoes?

Scientists monitor volcanoes for signs of potential eruptions by using instruments like seismometers to measure earthquake activity, and by observing changes in the volcano's appearance.

How can scientists use data to predict volcanic eruptions?

Data like increased earthquake frequency, landslides, and ash clouds can be used to predict volcanic eruptions because these events often precede eruptions.

Which volcano is most likely to erupt?

Volcano 2 shows signs of pressure building up, such as ground swelling, increased earthquakes, and vapor emission. These indicate a potential eruption, making it the most likely to erupt soon.

Why is Volcano 3 less likely to erupt?

Volcano 3 erupted recently (50 years ago), so it hasn't built up enough pressure to cause an immediate eruption.

Why is Volcano 4 considered inactive?

Volcano 4 lacks observable changes, indicating a dormant state and making it the least likely to erupt soon.

How does time since the last eruption affect eruption likelihood?

The time since the last eruption plays a crucial role in determining the likelihood of an eruption. Longer periods since the last eruption often indicate higher pressure build-up and an increased likelihood of eruption.

What factors determine the likelihood of a volcanic eruption?

Not all volcanoes are equally likely to erupt. Scientists use various factors to assess the risk and predict which volcanoes are most prone to an eruption.

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.
