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 15:41 local solar time at the epicentre, during the afternoon.

This event was deeper than 86% of the 461 earthquakes recorded in Canada in our catalogue and stronger than 97% of them.

Where was the epicentre?

The epicentre was located at 51.5640, -131.0360 — 297 km west-northwest of Port McNeill. The closest other recorded event was a magnitude 4.0 earthquake 36 km east-southeast of here on 07 September 2025.

The nearest other settlement in our records is Prince Rupert (116 km north-northwest).

Why the 13 km depth matters

At 13 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 event record links to NOAA tsunami information because this was a large event in an oceanic region. That link flag does not mean a tsunami occurred or that a warning is active. Check tsunami.gov and instructions from your local authority for the current status of your coastline.

Aftershocks and local seismic history

1 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 4.0.

11 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.6 event near Port McNeill on 01 August 2026. This M4.4 event released about 63 times less energy than that event.

No other earthquakes have been recorded within 100 km of this epicentre in the past year, which makes this a genuinely isolated event.

Questions about this earthquake

How strong was the earthquake near Port McNeill?

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 Port McNeill?

The focus was 13 km below the surface, which counts as shallow.

Was the Port McNeill earthquake felt at the surface?

At magnitude 4.4 and a focal depth of 13 km, shaking would have been concentrated near the epicentre.

When did the earthquake near Port McNeill happen?

03 February 2025 at 00:25 UTC.

Was there a tsunami?

The USGS record carries a link to NOAA tsunami information for this event. That is not a warning: check your regional tsunami warning centre for any live alert.

Have there been aftershocks?

1 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 4.0.

How often do earthquakes happen near Port McNeill?

11 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.6 event near Port McNeill on 01 August 2026. This M4.4 event released about 63 times less energy than that event.
