How strong was this earthquake?

Strong earthquakes can cause significant damage in populated areas within roughly 100 km of the epicentre, particularly to older masonry buildings. Landslides and liquefaction become a real risk in susceptible ground.

A magnitude 6.0 earthquake radiates roughly 15,080 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 554, 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 00:52 local solar time at the epicentre, in the early hours of the morning.

This event was shallower than 52% of the 1,906 earthquakes recorded in Russia in our catalogue and stronger than 98% of them.

Where was the epicentre?

The epicentre was located at 51.6081, 159.5470 — 166 km south-southeast of Vilyuchinsk. The closest other recorded event was a magnitude 4.8 earthquake 2 km west-southwest of here on 04 June 2026.

The nearest other settlements in our records are Petropavlovsk-Kamchatsky (111 km east) and Ozernovskiy (134 km south-southeast).

Why the 20 km depth matters

At 20 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 can produce strong, widely felt shaking. 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 M6.0 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

116 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.8.

1370 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 8.7 event near Petropavlovsk-Kamchatsky on 29 July 2025. This M6.0 event released about 11,220 times less energy than that event.

163 earthquakes have been recorded within 100 km of this epicentre in the past year, 162 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Vilyuchinsk?

It measured magnitude 6.0 — a strong earthquake. A magnitude 6.0 earthquake radiates roughly 15,080 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Vilyuchinsk?

The focus was 20 km below the surface, which counts as shallow.

Was the Vilyuchinsk earthquake felt at the surface?

At magnitude 6.0 and a focal depth of 20 km, shaking would have been concentrated near the epicentre.

When did the earthquake near Vilyuchinsk happen?

02 August 2025 at 14:14 UTC.

Was there a tsunami?

No. The USGS record carries no tsunami-information link for this event.

Have there been aftershocks?

116 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.8.

How often do earthquakes happen near Vilyuchinsk?

1370 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 8.7 event near Petropavlovsk-Kamchatsky on 29 July 2025. This M6.0 event released about 11,220 times less energy than that event.
