Magnitude 5.5 earthquake — east central Pacific Ocean

A magnitude 5.5 earthquake struck the east central Pacific Ocean on 10 August 2026 at 05:41:44 UTC, according to the United States Geological Survey (USGS). The quake was centred at approximately 0.31°N, 114.65°W, roughly in the remote open waters west of Central America and east of the Galápagos Islands, at a shallow depth of about 10 kilometres. The USGS assigned the event a significance score of 465 and automatically generated ShakeMap and loss-estimation products, standard procedure for earthquakes of this size, though no tsunami warning was issued.

The epicentre lies along the Galápagos Spreading Centre, a section of mid-ocean ridge where the Cocos and Nazca tectonic plates diverge, an area that experiences frequent moderate seismic activity as new oceanic crust is formed. Because the earthquake occurred far from any populated landmass, the USGS recorded no "felt" reports from the public and no damage or casualties have been reported. Given the shallow depth and offshore location well away from coastlines, authorities did not consider the event a tsunami risk, and no further advisories followed its occurrence.
