Minimal impact predicted

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

One person injured at Camana; several homes destroyed and landslides reported in the Caravel?-Yauca area; 2 buildings damaged at Chala; some buildings damaged at Atiquipa.

Based on scientific estimates by the 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 97% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 0.8 million people exposed to shaking

This earthquake may have been felt by around 0.8 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.

Very strong shaking and likely moderate damage may have been experienced by an estimated 10 people. At VII, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 590 thousand). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Peru .

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.

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.

Earthquakes like this are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since December 20th, 2023, when a 6.2 magnitude earthquake hit 203 km (126 mi) further east. An even stronger magnitude 7.1 earthquake struck on January 14th, 2018.

In total, 4 earthquakes with a magnitude of 6 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 years.

Low 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.

Based on early data it appears this earthquake was not strong enough (lower than MAG-6.5) to be likely to cause destructive tsunami's. However this earthquake appeared to have hit at a shallow depth under sea, so 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 This earthquake appears to have struck under the sea. Not this earthquake.
This earthquake had a magnitude of 6. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 23 km (14 mi). Earthquakes this shallow could trigger a tsunami.
