'Any rainfall, which can be triggered by the ash sent into the atmosphere, could cause a landslide if the unstable rocks come loose.' 'When you get an eruption like this, the ash deposits very quickly and creates rocks which are extremely unstable. 'It's still not safe for rescue workers to land on the island,' Professor Elders said. This in turn could cause unstable rock, which formed immediately after the eruption, to be washed down the sides of the volcano in a landslide, with potentially fatal consequences for both rescue workers and the tourists who are still on the island. The devastating volcanic eruption on New Zealand's White Island, which has already claimed at least five lives, could trigger subsequent landslides, eruptions and tsunamis, scientists have warned.Ĭhris Elders, professor of Geology at Curtin University's School of Earth and Planetary Sciences, told MailOnline that the ash belching out from Volcano Whakaari could trigger a downpour of rain.Īsh particles thrown up into the atmosphere are good at attracting and collecting water droplets in clouds, resulting in heavy rain after an eruption.
