What Happened

A M 5.4 mww earthquake struck the southern East Pacific Rise at 12:47 UTC on September 10, 2026 (Unix time 1789064478934). The event was centered at latitude -34.8341, longitude -109.1514, with a depth of 10 km.

Location Details

The epicenter was located in the southern East Pacific Rise, an oceanic region far from populated land. The shallow depth of 10 km places it in the shallow category (<20 km).

Impact Assessment

No felt reports were recorded. The USGS issued a green alert level. No tsunami was generated (tsunami flag: 0).

What You Should Know
