Magnitude 7.8 earthquake recorded 25 km SW of Kablalan, Philippines

The United States Geological Survey recorded a magnitude 7.8 earthquake 25 km SW of Kablalan, Philippines on 7 June 2026.

The United States Geological Survey (USGS) recorded an earthquake of magnitude 7.8 on the moment magnitude (Mww) scale at 23:37 UTC on 7 June 2026. USGS gives the depth as 57.0 km and describes the location as “25 km SW of Kablalan, Philippines”.

USGS lists the solution status for this record as “reviewed”. The agency revises earthquake parameters as more instrument data arrives, so magnitude and depth can change after first publication. Any such change is shown in the revision history on this page.

This brief reports only what the USGS record states: magnitude, location, depth and time. It does not describe shaking felt, damage, casualties or any consequence of the earthquake, because the record used here does not establish those things.

Assembled from the source record listed under evidence. This record predates the start of this service's coverage and was added when the source was first read.

Limits of this brief

Reviewed earthquakes of magnitude 6.0 and above, worldwide. Only magnitude, location, depth and time are reported, together with any later revision USGS makes. Automatic solutions USGS has not yet reviewed, events it classifies as something other than an earthquake, and anything below magnitude 6.0 are not reported. Effects, damage and casualties are never reported, because the USGS record used here does not establish them.
