Minimal impact predicted

The US Geographic Survey (USGS) describes the impact of this earthquake as follows:

Several homes and buildings damaged at Prague.

Based on scientific estimates by the 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 82% likelyhood of between 0 and 1 million US Dollars in economic damage and impact, and a 99% chance that the economic impact of this earthquake falls no higher than 10 million USD.

Roughly 4.4 million people exposed to shaking

This earthquake may have been felt by around 4.4 million 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.

An estimated 250 people were exposed to level VII. At this level, very strong shaking and likely moderate damage can be expected. The majority of people (roughly 2.5 million) live in an area exposed to level IV, where light shaking and likely 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 Shawnee in Oklahoma, The United States. Shawnee is located 17 miles (27 km) north-northeast of the epicenter. Shawnee experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

Multiple large cities are in proximity of today's earthquake. Oklahoma City is located 43 mi to the west and experienced an intensity of IV (light shaking, likely no damage). Tulsa is located 61 mi to the north-east and experienced an intensity of IV (light shaking, likely no damage). Norman is located 43 mi to the west-southwest and experienced an intensity of III (weak shaking, probably 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?

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

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.

This is the strongest earthquake in 7 years

Earthquakes of this strength are not so common in the region, but it's not the first time. This is the strongest earthquake to hit since September 3rd, 2016, when a 5.8 magnitude earthquake hit 62 mi (100 km) further north. That was also the heaviest earthquake to hit the region in the past 10 years.

In total, 1 earthquake with a magnitude of 5.1 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 10 years.

Tsunami very unlikely

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.

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.

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 5.1. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 2 mi (3 km). Earthquakes this shallow could trigger a tsunami.
