Magnitude 6.2 earthquake recorded South Sandwich Islands region
The United States Geological Survey recorded a magnitude 6.2 earthquake South Sandwich Islands region on 2 September 2026.
Magnitude 6.2, on the moment magnitude (Mww) scale, solution status “reviewed”.
The scale is logarithmic: each whole step is roughly thirty-two times the energy
of the step below it, so distance along this axis is not distance in size.
Magnitude, location, depth and time are all this record establishes — it says
nothing about shaking felt, damage or casualties.
The hypocentre — where the rupture began — is recorded at 111 kilometres
below the surface, South Sandwich Islands region. Depth is one of the four
things this record establishes. It is not a measure of severity, and nothing here
indicates what was felt at the surface.
The United States Geological Survey (USGS) recorded an earthquake of magnitude 6.2 on the moment magnitude (Mww) scale at 23:46 UTC on 2 September 2026. USGS gives the depth as 111.0 km and describes the location as “South Sandwich Islands region”.
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 6.2 earthquake recorded South Sandwich Islands region
The United States Geological Survey (USGS) recorded an earthquake of magnitude 6.2 on the moment magnitude (Mww) scale at 23:46 UTC on 2 September 2026. USGS gives the depth as 125.9 km and describes the location as “South Sandwich Islands region”.
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.
12 September 2026, 01:09 UTC — First publication
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.
What this record does not establish
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.
