Deep Earth’s Quiet Aftermath: Why Seismic Healing Persists Longer at Mid- crust Depths
Introduction: The Hidden Timeline of Post-Seismic Deformation Earthquakes grab headlines with dramatic ruptures and surface destruction, but the story of how the Earth settles after a quake runs much deeper. Post-seismic deformation refers to the slow adjustment of rocks around an earthquake as new stresses redistribute after the initial rupture. While society tends to focus…
