A sleeping giant's heartbeat
Mount Ararat, a compound stratovolcano reaching 5,137 meters (16,854 feet), appears quiet. For centuries, its twin snow-capped peaks, Greater and Lesser Ararat, have stood silent over the plains of eastern Turkey. The last confirmed magmatic eruption occurred around 2,500 years ago, with pyroclastic flows burying Early Bronze Age settlements. A more recent event in 1840 was a steam-driven phreatic eruption, triggered by a massive magnitude 7.4 earthquake. This event caused a gigantic landslide on the northern flank, obliterating the village of Akori and killing up to 10,000 people in the region.
Despite this long magmatic silence, modern geophysical techniques suggest the volcano is dormant, not extinct. Seismic tomography, a method that uses earthquake waves to create a 3D image of the Earth's subsurface, has detected a low-velocity anomaly beneath the massif. This zone, centered at a depth of around 15 kilometers, indicates the presence of partially molten rock. The seismic waves slow down as they pass through this material, showing a potential magma chamber that could be the source of future eruptions. The findings challenge the perception of Ararat as a permanently inactive feature and place it back on the list of potentially hazardous volcanoes.
