M5.6 earthquake – southern East Pacific Rise (Updated)
An M5.6 earthquake was recorded at 06:43 UTC on June 14, 2025, on the southern East Pacific Rise. The event occurred at a shallow depth of 10.0 km (6.2 miles).
The epicenter was located at coordinates 36.6°S, 110.6°W in the southern segment of the East Pacific Rise, a distant mid-ocean ridge situated in the southeast Pacific Ocean, well away from any populated landmass.
Given the remote mid-ocean location, critical infrastructure such as ports, airports, or populated coastal regions are not in the immediate vicinity of the epicenter. The surrounding area is characterized by open ocean and submarine tectonic features.
There is no tsunami threat associated with this earthquake, based on its location and available data.
The significance index is 482 (on a scale that runs through 1 000), based on magnitude and estimated impact.
The East Pacific Rise is a major tectonic plate boundary where the Pacific Plate and Nazca Plate diverge, leading to frequent moderate to strong seismic activity along the spreading ridge.
