‘Bulges’ in volcanoes could be used to predict eruptions

by University of Cambridge, June 28, 2017 in ScienceDaily


Using a technique called ‘seismic noise interferometry’ combined with geophysical measurements, the researchers measured the energy moving through a volcano. They found that there is a good correlation between the speed at which the energy travelled and the amount of bulging and shrinking observed in the rock. The technique could be used to predict more accurately when a volcano will erupt. Their results are reported in the journal Science Advances.

The University of Iowa volcanologist spent her days collecting samples from a volcano on Tanna, an island in the remote South Pacific archipelago of Vanuatu. The volcano, called Yasur, spews out flaming masses or “bombs” – some the size of a small car.

This has real health implications,” Ukstins says. “It means more than simply studying volcanoes.”
