Potential tsunami risk

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

There is a potential tsunami risk in the aftermath of this earthquake, immediately evacuate to higher grounds away from coastal areas and monitor advice from local authorities. The US Geographic Survey organization has indicated a potential risk for tsunami's following this earthquake.

Tsunami Risk Factors

Factor Under Sea? MAG-6.5 or stronger? Shallow depth?
Explanation Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake This earthquake appears to have struck on land near a coastal area (2 mi from the sea). Not this earthquake.
This earthquake had a magnitude of 4.3. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 5 mi (8 km). Earthquakes this shallow could trigger a tsunami.

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 12 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 12 million have been exposed to shaking at an MMI level of II or higher.

Moderate shaking and very light damage may have been experienced by an estimated 35,760 people. At V, it is the highest MMI level this earthquake has caused. The majority of people (roughly 5.1 million) live in an area exposed to level II, where very weak shaking and no damage is expected.

Nearby towns and cities

This earthquake may have been felt in The United States . The closest significant population center near the earthquake is Berkeley in California, The United States. Berkeley is located 1 miles (2 km) east-southeast of the epicenter. Berkeley experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Major cities near this earthquake: Berkeley is located 1 mi to the west-northwest and experienced an intensity of IV (light shaking, likely no damage). Oakland is located 4 mi to the south-southwest and experienced an intensity of IV (light shaking, likely no damage). San Francisco is located 11 mi to the southwest and experienced an intensity of IV (light shaking, likely no damage).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.

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.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this earthquake.
