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 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 312, 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 09:53 local solar time at the epicentre, during the morning.

This event was deeper than 98% of the 1,952 earthquakes recorded in Russia in our catalogue and stronger than 20% of them.

Where was the epicentre?

The epicentre was located at 54.0004, 158.1850 — 82 km south-southwest of Mil’kovo. The closest other recorded event was a magnitude 4.7 earthquake 83 km east-southeast of here on 13 November 2025.

The nearest other settlements in our records are Yelizovo (72 km south-southeast), Mil’kovo (81 km east), Пионерское (145 km northeast) and Paratunka (152 km south-southwest).

Why the 183 km depth matters

At 183 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 M4.5 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 183 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.

226 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 8.0 event near Petropavlovsk-Kamchatsky on 29 July 2025. This M4.5 event released about 177,828 times less energy than that event.

1 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 Mil’kovo?

It measured magnitude 4.5 — a light earthquake. A magnitude 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Mil’kovo?

The focus was 183 km below the surface, which counts as intermediate.

Was the Mil’kovo earthquake felt at the surface?

At magnitude 4.5 and a focal depth of 183 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Mil’kovo happen?

14 October 2026 at 23:20 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 Mil’kovo?

226 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 8.0 event near Petropavlovsk-Kamchatsky on 29 July 2025. This M4.5 event released about 177,828 times less energy than that event.
