"Unleashing Destruction: Magma's Path through Extinct Volcano Triggers Deadly Earthquake Swarm in Japan"

A swarm of earthquakes that has been occurring in Japan for three years is believed to be caused by liquid magma moving through an extinct volcano beneath the Noto Peninsula. The earthquakes, which have resulted in over 1,000 magnitude 2 or larger quakes, including a magnitude 6.5 quake that caused one fatality, are occurring in a pattern consistent with fluid ascending through a network of faults in an ancient, collapsed caldera. The researchers are now investigating how the swarm transitioned to the large, damaging earthquake and are studying the fluid and aseismic slip conditions prior to the event.
