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 2.3 million people exposed to shaking

An estimated 2.3 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.

Light shaking and likely no damage may have been experienced by an estimated 890 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 1.6 million). In their region, weak shaking and probably no damage can be expected.

3 Aftershocks detected

This main shock was followed by 3 smaller aftershocks. Just 21 hrs after this main shock, an earthquake measuring MAG-2.9 was detected 0.2 mi (0.3 km) west-northwest of this earthquake.

Before this earthquake struck, 1 smaller foreshock occurred. Nearby this earthquake a foreshock struck 2 days earlier. It measured a magnitude of 2.5

Overview of foreshocks and aftershocks

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.
Classification	Magnitude	When	Where
Foreshock	M 2.5	2 days earlier Aug 11, 2024 10:22AM (Los Angeles Time)	56 mi (90 km) NE from Main Shock.
Main Shock This Earthquake	M 4.4	Aug 13, 2024 08:06PM (Los Angeles Time)	-
Aftershock	M 2.9	6 mins later Aug 13, 2024 08:12PM (Los Angeles Time)	0.5 mi (0.8 km) W from Main Shock.
Aftershock	M 2.9	11 hrs later Aug 14, 2024 07:06AM (Los Angeles Time)	0.5 mi (0.8 km) NNW from Main Shock.
Aftershock	M 2.9	21 hrs later Aug 14, 2024 05:03PM (Los Angeles Time)	0.2 mi (0.3 km) WNW from Main Shock.

More earthquakes coming?

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.

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. This is the strongest earthquake to hit since July 29th, 2024, when a 4.9 magnitude earthquake hit 131 mi (210 km) further south-southwest. An even stronger magnitude 7.1 earthquake struck on July 6th, 2019.

In total, 94 earthquakes with a magnitude of 4.4 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 month.

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 4.4. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 8 mi (13 km). Earthquakes this shallow could trigger a tsunami.
