How strong was this earthquake?

Moderate earthquakes can damage poorly built or unreinforced structures near the epicentre, while well-engineered buildings typically escape serious harm. Shaking is often strong enough to wake sleeping residents over a wide area.

A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 482, 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 11:42 local solar time at the epicentre, during the morning.

This event was deeper than 99% of the 1,906 earthquakes recorded in Russia in our catalogue and stronger than 96% of them.

Where was the epicentre?

The epicentre was located at 47.5925, 147.3610 — 265 km north of Kuril’sk. The closest other recorded event was a magnitude 4.9 earthquake 40 km north of here on 28 March 2025.

The nearest other settlements in our records are Makarov (91 km west-northwest) and Poronaysk (98 km northwest).

Why the 403 km depth matters

At 403 km this was a deep-focus earthquake, occurring well inside the subducting slab rather than in the crust. Deep events are rarely damaging even at large magnitudes, though they can be felt over very long distances.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size can be felt widely and may cause minor local damage. Its deep focus normally weakens surface shaking while spreading perceptible motion over a broad area.

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 M5.6 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 403 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 in the seven days after this event.

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 5.2 event near northwest of the Kuril Islands on 05 January 2026. This M5.6 event released about 4.0 times more energy than that event.

4 earthquakes have been recorded within 100 km of this epicentre in the past year, 1 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Kuril’sk?

It measured magnitude 5.6 — a moderate earthquake. A magnitude 5.6 earthquake radiates roughly 3,788 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Kuril’sk?

The focus was 403 km below the surface, which counts as deep.

Was the Kuril’sk earthquake felt at the surface?

At magnitude 5.6 and a focal depth of 403 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Kuril’sk happen?

12 January 2026 at 01:52 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 Kuril’sk?

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 5.2 event near northwest of the Kuril Islands on 05 January 2026. This M5.6 event released about 4.0 times more energy than that event.
