Magnitude 6.5 earthquake recorded 126 km NNE of Teluknaga, Indonesia

The United States Geological Survey recorded a magnitude 6.5 earthquake 126 km NNE of Teluknaga, Indonesia on 11 September 2026.

The United States Geological Survey (USGS) recorded an earthquake of magnitude 6.5 on the moment magnitude (Mww) scale at 21:23 UTC on 11 September 2026. USGS gives the depth as 372.0 km and describes the location as “126 km NNE of Teluknaga, Indonesia”.

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.

Magnitude 6.6 earthquake recorded 115 km NNE of Teluknaga, Indonesia

The United States Geological Survey (USGS) recorded an earthquake of magnitude 6.6 on the moment magnitude (Mww) scale at 21:23 UTC on 11 September 2026. USGS gives the depth as 358.6 km and describes the location as “115 km NNE of Teluknaga, Indonesia”.

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.
