Next Supervolcano Eruption May Happen Without Any Impending Warning, Experts Claim

According to a recent study of the Toba volcano in Sumatra, Indonesia, some of the primary warning indicators that geologists usually watch out for before a supervolcanic eruption may not really be present in every instance. A quick rush of magma into the volcano's reservoir may not have preceded Toba's massive eruptions 840,000 years ago and 75,000 years ago, according to the findings.
