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 4.4 earthquake radiates roughly 60 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 298, 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 22:50 local solar time at the epicentre, late at night.

This event was deeper than 76% of the 1,501 earthquakes recorded in Indonesia in our catalogue and stronger than 12% of them.

Where was the epicentre?

The epicentre was located at 2.7883, 128.6400 — 136 km north-northeast of Tobelo. The closest other recorded event was a magnitude 4.8 earthquake 11 km west-southwest of here on 19 July 2026.

The nearest other settlements in our records are Pulau Morotai (47 km south), Cio Dalam (59 km southwest), Tobelo (156 km south-southwest) and Maba (177 km south).

Why the 100 km depth matters

At 100 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 M4.4 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 100 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 since this event was recorded.

187 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 Tobelo on 10 January 2026. This M4.4 event released about 2,818 times less energy than that event.

21 earthquakes have been recorded within 100 km of this epicentre in the past year, 0 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Tobelo?

It measured magnitude 4.4 — a light earthquake. A magnitude 4.4 earthquake radiates roughly 60 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Tobelo?

The focus was 100 km below the surface, which counts as intermediate.

Was the Tobelo earthquake felt at the surface?

At magnitude 4.4 and a focal depth of 100 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Tobelo happen?

03 September 2026 at 14:15 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 since this event was recorded.

How often do earthquakes happen near Tobelo?

187 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 Tobelo on 10 January 2026. This M4.4 event released about 2,818 times less energy than that event.
