Dormant Greek Volcano Reveals Hidden Magma Under 100,000-Year Silence
A new study of the Methana volcano near Athens shows 700,000 years of activity with 31 eruptions, including a nearly 100,000-year quiet interval during which magma continued accumulating underground. The surface calm did not mean safety, challenging the idea that long dormancy equates to extinction and suggesting huge underground reservoirs can fuel powerful future eruptions. The finding urges a reassessment of volcanic risk for “extinct” volcanoes and underscores the need for deeper monitoring in subduction-zone regions.
