1 year warning may precede catastrophic volcanic eruptions

Scientists have analyzed tiny quartz crystals to determine the amount of lead time humanity might have before an enormous volcanic eruption, and their conclusion is that there may only be one year of warning. The researchers focused on the kinds of giant volcanic eruptions that haven’t happened for a very, very long time, like a super eruption in New Zealand that occurred 26,500 years ago. First, a huge amount of magma has to build up, which can persist for hundreds or even thousands of years. Then, it needs to erupt. And, according to a new study, it might just take a year for the actual eruption process— that transition from build-up to eruption— to happen. “e have shown that the onset of the process of decompression, which releases the gas bubbles that power the eruption, starts less than a year before eruption,” Guilherme Gualda, an associate professor at Vanderbilt University and first author of the new study, said in a statement.
