Aseismic slip and seismic swarms preceding Taiwan’s 2024 M7.3 Hualien earthquake
Years before the ground shook across eastern Taiwan, the faults beneath Hualien were already in motion. A new study in Nature Communications shows that deep aseismic slip and migrating fluids quietly increased stress by about 30 kilopascals before the April 3, 2024 M7.3 Hualien earthquake, revealing how silent deformation can set the stage for disaster.
