Researchers led by Răzvan-Gabriel Popa analyzed over 1,250 zircon crystals from Methana, about 60 km southwest of Athens.
Their study reveals Methana experienced a 112,000-year dormant period, with magma accumulating underground, challenging the idea that 10,000 years of inactivity means extinction.
These findings suggest many seemingly inactive volcanoes worldwide may still build magma chambers, prompting calls for improved monitoring and reassessment of volcanic hazards.
