How strong was this earthquake?

Light earthquakes are widely felt near the epicentre and can rattle windows, dishes and hanging objects. Damage is uncommon and usually limited to cracked plaster or fallen loose items.

A magnitude 4.6 earthquake radiates roughly 120 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 326, 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.

When it happened locally

That is about 23:47 local solar time at the epicentre, late at night.

This event was deeper than 87% of the 135 earthquakes recorded in the Solomon Islands in our catalogue and stronger than 19% of them.

Where was the epicentre?

The epicentre was located at -12.1271, 166.5080 — 173 km south-southeast of Lata. The closest other recorded event was a magnitude 4.9 earthquake 11 km north of here on 14 October 2025.

The nearest other settlement in our records is Sola (235 km south-southeast).

Why the 104 km depth matters

At 104 km this was an intermediate-depth earthquake. Energy from events at this depth spreads out before it reaches the surface, which usually means weaker shaking near the epicentre than a shallow quake of the same magnitude, but shaking felt across a wider area.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size is often felt across the surrounding area. Its intermediate depth normally reduces peak shaking near the epicentre compared with a shallow 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 M4.6 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 104 km focal depth is too great to deform the sea floor significantly; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

Aftershocks and local seismic history

No further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event.

87 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.3 event near Lata on 14 August 2025. This M4.6 event released about 355 times less energy than that event.

35 earthquakes have been recorded within 100 km of this epicentre in the past year, 6 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Lata?

It measured magnitude 4.6 — a light earthquake. A magnitude 4.6 earthquake radiates roughly 120 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Lata?

The focus was 104 km below the surface, which counts as intermediate.

Was the Lata earthquake felt at the surface?

At magnitude 4.6 and a focal depth of 104 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Lata happen?

03 September 2025 at 12:41 UTC.

Was there a tsunami?

No. The USGS record carries no tsunami-information link for this event.

Have there been aftershocks?

No further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event.

How often do earthquakes happen near Lata?

87 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.3 event near Lata on 14 August 2025. This M4.6 event released about 355 times less energy than that event.
