Active volcanoes are sometimes linked to Tsunamis.
2. Dormant volcano
The volcano is inactive and has not been known to erupt in recent times.
Dormant may erupt again and recent studies have shown that some of the dormant volcano volcanoes are only going through what is known as the recharge period which may last for tens of thousands of years after which they will erupt again.
Dormant volcanoes are currently quiet but may erupt again.
