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 16:26 local solar time at the epicentre, during the afternoon.

This event was deeper than 57% of the 593 earthquakes recorded in Papua New Guinea in our catalogue and stronger than 7% of them.

Where was the epicentre?

The epicentre was located at -6.3846, 147.8480 — 19 km north of Finschhafen. The closest other recorded event was a magnitude 4.9 earthquake 17 km west-southwest of here on 28 June 2026.

The nearest other settlements in our records are Kanzarua (30 km northwest), Finschhafen (103 km south), Lae (110 km south-southwest) and Kimbe (130 km east-northeast).

Why the 65 km depth matters

At 65 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.

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 shallow focus makes stronger surface shaking more likely than for a deeper 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; 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.

138 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 Lae on 07 October 2025. This M4.4 event released about 2,818 times less energy than that event.

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