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 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 312, 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 21:20 local solar time at the epicentre, late at night.

This event was deeper than 88% of the 187 earthquakes recorded in Timor-Leste in our catalogue and stronger than 47% of them.

Where was the epicentre?

The epicentre was located at -7.1972, 126.0090 — 145 km north of Manatutu. The closest other recorded event was a magnitude 4.7 earthquake 11 km southwest of here on 12 September 2025.

The nearest other settlements in our records are Metinaro (33 km west), Baukau (44 km southeast), Dili (81 km west-northwest) and Likisá (94 km west).

Why the 492 km depth matters

At 492 km this was a deep-focus earthquake, occurring well inside the subducting slab rather than in the crust. Deep events are rarely damaging even at large magnitudes, though they can be felt over very long distances.

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 deep focus normally weakens surface shaking while spreading perceptible motion over a broad area.

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 M4.5 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 492 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.

109 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 Lospalos on 24 August 2026. This M4.5 event released about 178 times less energy than that event.

4 earthquakes have been recorded within 100 km of this epicentre in the past year, 2 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Manatutu?

It measured magnitude 4.5 — a light earthquake. A magnitude 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Manatutu?

The focus was 492 km below the surface, which counts as deep.

Was the Manatutu earthquake felt at the surface?

At magnitude 4.5 and a focal depth of 492 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Manatutu happen?

28 March 2025 at 12:56 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 Manatutu?

109 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 Lospalos on 24 August 2026. This M4.5 event released about 178 times less energy than that event.
