How strong was this earthquake?

Moderate earthquakes can damage poorly built or unreinforced structures near the epicentre, while well-engineered buildings typically escape serious harm. Shaking is often strong enough to wake sleeping residents over a wide area.

A magnitude 5.1 earthquake radiates roughly 674 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 400, 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 06:34 local solar time at the epicentre, around dawn.

This event was shallower than 77% of the 190 earthquakes recorded in Timor-Leste in our catalogue and stronger than 91% of them.

Where was the epicentre?

The epicentre was located at -7.5087, 128.8550 — 233 km east-northeast of Lospalos. The closest other recorded event was a magnitude 4.2 earthquake 17 km north of here on 25 July 2026.

The nearest other settlements in our records are Maluku (138 km west), Ambon (140 km north-northwest), Tual (193 km east-northeast) and Amahai (233 km north-northeast).

Why the 102 km depth matters

At 102 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 can be felt widely and may cause minor local damage. 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 M5.1 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 102 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

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 4.5.

278 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.4 event near Banda Sea on 28 October 2025. This M5.1 event released about 89 times less energy than that event.

61 earthquakes have been recorded within 100 km of this epicentre in the past year, 8 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Lospalos?

It measured magnitude 5.1 — a moderate earthquake. A magnitude 5.1 earthquake radiates roughly 674 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Lospalos?

The focus was 102 km below the surface, which counts as intermediate.

Was the Lospalos earthquake felt at the surface?

At magnitude 5.1 and a focal depth of 102 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Lospalos happen?

12 January 2026 at 21:59 UTC.

Was there a tsunami?

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

Have there been aftershocks?

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 4.5.

How often do earthquakes happen near Lospalos?

278 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.4 event near Banda Sea on 28 October 2025. This M5.1 event released about 89 times less energy than that event.
