How strong was this earthquake?

Micro earthquakes are almost never felt at the surface and are recorded only by seismographs.

A magnitude 1.8 earthquake radiates roughly 7.6 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 50, 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 00:45 local solar time at the epicentre, in the early hours of the morning.

This event was deeper than 86% of the 460 earthquakes recorded in Canada in our catalogue and stronger than 46% of them.

Where was the epicentre?

The epicentre was located at 47.6261, -70.0172 — 10 km east-southeast of La Malbaie. The closest other recorded event was a magnitude 2.6 earthquake 3 km north-northeast of here on 25 July 2025.

The nearest other settlements in our records are Saint-Pacôme (11 km south), Saint-Pascal (13 km east), Saint-Siméon (21 km north-northeast) and L'Isle-aux-Coudres (38 km southwest).

Why the 14 km depth matters

At 14 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, events this small are usually detected by instruments rather than people. 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 M1.8 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 in the seven days after this event.

1 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.4 event near Mont-Joli on 18 June 2026. This M1.8 event released about 7,943 times less energy than that event.

5 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 La Malbaie?

It measured magnitude 1.8 — a micro earthquake. A magnitude 1.8 earthquake radiates roughly 7.6 kg of TNT equivalent in seismic energy.

How deep was the earthquake near La Malbaie?

The focus was 14 km below the surface, which counts as shallow.

Was the La Malbaie earthquake felt at the surface?

At magnitude 1.8 and a focal depth of 14 km, shaking would have been concentrated near the epicentre.

When did the earthquake near La Malbaie happen?

30 May 2025 at 05:25 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 La Malbaie?

1 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.4 event near Mont-Joli on 18 June 2026. This M1.8 event released about 7,943 times less energy than that event.
