M5.5 earthquake — Pacific-Antarctic Ridge

M5.5 earthquake near Pacific-Antarctic Ridge

A moderate magnitude 5.5 earthquake occurred Pacific-Antarctic Ridge on Jul 20, 2026 at 05:38 UTC. The epicenter was at a depth of 10 km — a shallow earthquake. Shallow quakes concentrate their energy near the surface, so they tend to produce stronger shaking close to the epicenter.

What this magnitude typically means

Moderate earthquakes are widely felt and can cause light damage close to the epicenter. The shaking you actually experience depends on how far away you are and what kind of ground you are on. Tremor does not compute a single local shaking figure here, because how strong a quake feels at any address depends on distance, depth and local geology — open the interactive globe to explore the ShakeMap and estimated intensity.
