Earthquakes could warn of volcanic eruptions

Earthquakes could act as an early warning system for volcanic eruptions, according to new research.

Researchers have found that some earthquakes are caused by a blockage in lava flow, which can be a pre-curser to an eruption.

They found that 36 hours before the 2006 Augustine Volcano eruption in Alaska, there was a swarm of 54 earthquakes triggered from sources within the volcano.

Researchers believe that these types of earthquakes signal that a volcano is becoming pressurised and near explosion, giving scientists time to alert the public of an imminent eruption.
