Potential tsunami risk
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 | Not this earthquake. This earthquake appears to have struck on land far from any coast. |
Not this earthquake. This earthquake had a magnitude of 4.7. Earthquakes of this strength are unlikely to trigger a tsunami. |
This earthquake occurred at a depth of of 1 mi (1 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 69% likelyhood of between 0 and 1 fatalities, and a 98% 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 100% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.
Roughly 10 million people exposed to shaking
An estimated 10 million have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.
The highest earthquake impact level for this earthquake is VI, which corresponds with strong shaking and probably light damage. Roughly 1,370 people are expected to be exposed to this level. The majority of people (roughly 9 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 . Located 11 miles (17 km) southwest of the epicenter of this earthquake, Clearlake (California, The United States) is the nearest significant population center. Clearlake experienced an earthquake intensity (MMI Scale) of roughly III. That level implies weak shaking and probably no damage.
Major cities near this earthquake: San Francisco is located 76 mi to the south-southeast and experienced an intensity of III (weak shaking, probably no damage). San Jose is located 114 mi to the south-southeast and experienced an intensity of I (not noticeable, no damage). Sacramento is located 70 mi to the east-southeast and experienced an intensity of II (very weak shaking, no damage).
The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

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 of this strength are very common in the region. This is the strongest earthquake to hit since December 15th, 2024, when a 5.3 magnitude earthquake hit 169 mi (271 km) further northwest. An even stronger magnitude 7 earthquake struck on December 5th, 2024.
In total, 29 earthquakes with a magnitude of 4.7 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.
