Mindanao Earthquake Permanently Lifted Seabed by Two Metres

A 7.8-magnitude earthquake struck south of Mindanao on June 8, 2026, killing at least 61 people. The rupture permanently raised the seafloor by up to two metres along affected coastlines—a coseismic uplift rarely observed in real time. The vertical displacement altered bathymetry and triggered measurable shoreline retreat along Sarangani Bay, requiring updated nautical charting. The phenomenon signals a shallow thrust-fault rupture, the geometry most associated with tsunami generation.
