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 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 2.2 million people exposed to shaking

An estimated 2.2 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.

Moderate shaking and very light damage may have been experienced by an estimated 1,450 people. At V, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 1.3 million). In their region, weak shaking and probably no damage can be expected.

Nearby towns and cities

This earthquake may have been felt in The United States . Located 15 miles (24 km) north of the epicenter of this earthquake, Salina (Kansas, The United States) is the nearest significant population center. The intensity of shaking and damage in Salina is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Multiple large cities are in proximity of today's earthquake. Wichita is located 96 mi to the south and experienced an intensity of III (weak shaking, probably no damage). Kansas City is located 164 mi to the east (intensity unknown, possibly low). Omaha is located 176 mi to the north-northeast (intensity unknown, possibly low).

A complete list of nearby places is included below. Estimated intensity data (MMI) sourced from a shake-map published by the US Geographic Survey is shown where available (cities without data probably experienced little impact).

Risk of aftershocks?

This earthquake did not have any significant foreshocks nor aftershocks occurring within 100km (62 mi) of its epicenter.

Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since January 31st, 2022, when a 4.5 magnitude earthquake hit 153 mi (245 km) further south. An even stronger magnitude 5.8 earthquake struck on September 3rd, 2016.

In total, 38 earthquakes with a magnitude of 4 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 3 months.

Tsunami very unlikely

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.
