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 4.2 earthquake radiates roughly 30 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 271, 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 10:06 local solar time at the epicentre, during the morning.

This event was shallower than 84% of the 187 earthquakes recorded in Timor-Leste in our catalogue and stronger than 18% of them.

Where was the epicentre?

The epicentre was located at -7.6079, 129.2400 — 266 km east-northeast of Lospalos. The closest other recorded event was a magnitude 4.2 earthquake 36 km north of here on 11 July 2026.

The nearest other settlements in our records are Ambon (164 km north-northwest), Maluku (180 km west), Tual (205 km east-northeast) and Amahai (225 km north-northeast).

Why the 85 km depth matters

At 85 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 M4.2 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; 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

3 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.3.

279 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.7 event near Tual on 14 July 2025. This M4.2 event released about 5,623 times less energy than that event.

59 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 Lospalos?

It measured magnitude 4.2 — a light earthquake. A magnitude 4.2 earthquake radiates roughly 30 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Lospalos?

The focus was 85 km below the surface, which counts as intermediate.

Was the Lospalos earthquake felt at the surface?

At magnitude 4.2 and a focal depth of 85 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Lospalos happen?

05 May 2026 at 01:29 UTC.

Was there a tsunami?

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

Have there been aftershocks?

3 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.3.

How often do earthquakes happen near Lospalos?

279 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.7 event near Tual on 14 July 2025. This M4.2 event released about 5,623 times less energy than that event.
