They create a system that predicts volcanic eruptions in real time


New Zealand scientists invented a volcanic activity alert system that they say could have prevented last year’s disaster on White Island.

In December, 21 people – including tourists – died when the country’s most active volcano, Whakaari, suddenly erupted.

BBC Shane Cronin of the University of Auckland, one of the scientists involved. ‘ data-reactid = “28”> “We noticed all but one eruption because it did not involve magma. It was an eruption of the surface system with a different type of precursor signal, ”Shane Cronin of the University of Auckland, one of the scientists involved, told the BBC.

“Therefore, we can identify the main type of eruptions and we are only trying to solve the second model,” he added.

Research on the new alert system was published last week in the journal Nature Communications.

According to Cronin, the previous alert system was “too slow to provide warnings to people on White Island. It collected data in real time, but that information had to be evaluated by a panel of experts. And that takes time. “

“The way we noticed volcano activity was very good 10 years ago, but it was not updated,” he added.

According to the expert, the development of the new warning system had begun before the White Island eruption, but “when the eruption occurred it really accelerated us. We think, we have to work on this now. “

He claims that if this system had been implemented in December, it could have alerted officials 16 hours before the eruption occurred.

Despite the mild seismic activity in the weeks leading up to the explosion on White Island, the sudden and dramatic nature of the eruption surprised everyone, including authorities.
