Volcano Hunters: Unit 3

A technique that volcanologists use to study volcanoes by creating models of volcanic features

Volcano has been active in the past, but has not erupted in the last 10,000 years...it may erupt in the future.

• Active Volcano

• Dormant Volcano

• Extinct Volcano

Volcano has not erupted for around 10,000 years, no longer has a magma supply, and is therefore unlikely to erupt again.

• Active Volcano

• Dormant Volcano

• Extinct Volcano

Volcano erupts regularly or has had at least one eruption in the last 10,000 years.

• Extinct Volcano

• Dormant Volcano
