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 4.8 earthquake radiates roughly 239 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 354, 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 15:09 local solar time at the epicentre, during the afternoon.

This event was shallower than 75% of the 188 earthquakes recorded in Timor-Leste in our catalogue and stronger than 75% of them.

Where was the epicentre?

The epicentre was located at -8.9389, 124.0320 — 48 km northwest of Pante Makasar. The closest other recorded event was a magnitude 4.5 earthquake 8 km south of here on 14 April 2026.

The nearest other settlements in our records are Naisano Dua (77 km south-southwest), Lembata (81 km north-northwest), Atambua (110 km east-southeast) and Maubara (111 km north-northeast).

Why the 107 km depth matters

At 107 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 M4.8 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 107 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.

72 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.2 event near Pante Makasar on 26 October 2025. This M4.8 event released about 126 times less energy than that event.

15 earthquakes have been recorded within 100 km of this epicentre in the past year, 3 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Pante Makasar?

It measured magnitude 4.8 — a light earthquake. A magnitude 4.8 earthquake radiates roughly 239 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Pante Makasar?

The focus was 107 km below the surface, which counts as intermediate.

Was the Pante Makasar earthquake felt at the surface?

At magnitude 4.8 and a focal depth of 107 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Pante Makasar happen?

25 August 2025 at 06:53 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 Pante Makasar?

72 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.2 event near Pante Makasar on 26 October 2025. This M4.8 event released about 126 times less energy than that event.
