Super-volcanoes greatest hazard on earth 31 March 2005 The world's super-volcanoes are well overdue for eruption which could have catastrophic effects for life on earth says Monash University researcher Professor Ray Cas. Professor Cas from the School of Geosciences says the 2000 year eruption cycle of many of these volcanoes has passed, leaving volcanologists around the globe watching and waiting. Super-volcanoes, which are the largest volcanoes on the planet, are found in Naples, New Zealand, Indonesia, South America and the US. "If any of these were to erupt we would see disaster on a magnitude greater than we have ever experienced," he says. "Naples alone supports a population of three million people so the potential for destruction and death is huge. These super-volcanoes are potentially the greatest hazard on earth, the only threat greater being an asteroid impact from space." Professor Cas says the eruption of one super-volcano could see 1000 cubic kilometres of rock and ash dispersed into the atmosphere and transformed into 200km per hour flows of gas and debris. Some of these could go into the sea, triggering devastating tsunamis. "The potential death toll could reach the hundreds of thousands to millions and there are serious implications on climate, weather and viability of food production," he says. "A super-volcano will definitely erupt, it is just a matter of time. It could be in a few, 50 or another 1000 years but sooner or later one is going to go off." Professor Cas is scheduled to begin an international collaborative project in South America next year to study super-volcanoes in the region. He plans to use the information to better understand super-volcano eruption patterns and identify signs they are about to erupt. ++++++++++++ Perasaan Ray tidak bilang Toba akan meletus, dia hanya bilang salah satu supervolcano yang akan meletus. Apakah itu Toba, atau di Italia sana, atau di Amerika Selatan atau di New Zealand?
