It’s rare to see a partially melted type of magma with such a large fluid component throughout the whole crust, he says.

At the moment, though, there’s no pool of liquid magma gathering near the surface – often a prelude to an eruption.

“One of the challenges now is to go beyond simply saying there’s magma in the crust, discovering instead how it’s sitting, how much there is and what are the implications,” says Hammond. “It’s only when it gets to a certain amount and a certain overpressure that it will erupt.”

At present, the researchers are not sure how much has to accumulate before the volcano erupts, he says.
