Scientists Discover New Volcanic Eruption Trigger

Scientists Discover New Volcanic Eruption TriggerScientists say they’ve found a new way to predict when a volcano is about to erupt. Simply; after a measurable pressure drop occurs within a volcano’s internal plumbing, an eruption is likely to follow.

This pressure drop can potentially be used by volcanologists to predict a catastrophic eruption. The researchers say the importance is quite significant, particularly if you are part of a community that lives next door to a volcano, or an airline company mapping flight routes.

The study is hoping to engineer early warning systems so that people can be told with a huge degree of confidence when to get out of the way.

Lead author Dr Janine Kavanagh from the University of Liverpool said with more than 600 million people worldwide living near a volcano at risk of eruptive activity, it is more important than ever that triggering mechanisms are made more accurate. This previously unrecognised trigger could also alleviate the “headache” volcanic eruptions cause civil aviation by providing early and accurate warnings to authorities when they should divert aircraft.

“There is also a strong economic incentive to understand the causes of volcanic activity as demonstrated in 2010 by the eruption of Eyjafjallajökull, Iceland, causing air-traffic disruption across Europe for more than a month, and an estimated $A2.5 billion loss in revenue to the airline industry :: Read the full article »»»»
