A catastrophic drop in atmospheric ozone layers 60 000 to 100 000 years ago likely contributed to a population bottleneck during that period. According to a new study, the event was triggered by the eruption of the Toba supervolcano in Sumatra, Indonesia. "Toba...

A new study suggests that Campi Flegrei, a volcano in the metropolitan area of Naples, one of the most densely inhabited areas in the world, may be near a critical pressure point which would reawaken it from its, almost 500 years long, sleep. In the course of a new...
