How strong was this earthquake?
Strong earthquakes can cause significant damage in populated areas within roughly 100 km of the epicentre, particularly to older masonry buildings. Landslides and liquefaction become a real risk in susceptible ground.
A magnitude 6.0 earthquake radiates roughly 15,080 tons of TNT equivalent in seismic energy.
The USGS assigns this earthquake a significance score of 554, which is below the USGS threshold of more than 600 for its significant-earthquake list. The ranking combines magnitude with available Did You Feel It responses and PAGER alert level; it is not a direct measurement of damage.
Where was the epicentre?
The epicentre was located at -45.6658, 96.3244. The closest other recorded event was a magnitude 5.9 earthquake 31 km north-northeast of here on 03 January 2026.
Why the 10 km depth matters
At 10 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.
This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size can produce strong, widely felt shaking. Its shallow focus makes stronger surface shaking more likely than for a deeper event of the same magnitude.
What does the tsunami information flag mean?
The USGS record does not carry a link to NOAA tsunami information. That field is not an all-clear and does not state whether a tsunami occurred. In this case, a damaging tsunami would be less likely because at M6.0 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami. For an active coastal alert, use tsunami.gov or your local warning authority.

Aftershocks and local seismic history
1 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.9.
5 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.0 event near southeast Indian Ridge on 31 October 2025. This M6.0 event released a comparable amount of energy to that event.
