The center of this earthquake had a quite shallow depth of 41 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Minimal impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 fatalities, and a 96% chance that the number of fatalities falls no higher than 10.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 65% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 96% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 260 thousand people exposed to shaking

This earthquake may have been felt by around 260 thousand people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

Light shaking and likely no damage may have been experienced by an estimated 24,630 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 230 thousand). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Russia .

Nearby towns and cities

This earthquake may have been felt in Russia . Located 146 kilometer (91 mi) south-east of the epicenter of this earthquake, Petropavlovsk-Kamchatsky (Kamchatka, Russia) is the nearest significant population center. The intensity of shaking and damage in Petropavlovsk-Kamchatsky is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

This is likely an aftershock

This earthquake is likely an aftershock of the MAG-6.1 earthquake that struck 2 days earlier. That main earthquake hit 21 km (13 mi) east-northeast of the epicenter of this MAG-6.0 aftershock.

Overview of foreshocks and aftershocks

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. In total, 33 earthquakes with a magnitude of 6 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 4 months.

Low tsunami risk

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so stay cautious and monitor advice from local authorities.
