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 1.4 million people exposed to shaking

The USGS has published a report estimating the number of people exposed to this earthquake. Acoording to their analysis, roughly 1.4 million have been exposed to shaking at an MMI level of II or higher.

The highest earthquake impact level for this earthquake is IV, which corresponds with light shaking and likely no damage. Roughly 645,700 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 0.8 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. In Panama , around 1.2 million people, with impact levels up to IV (light shaking, likely no damage). In Costa Rica , around 260 thousand people.

Nearby towns and cities

This earthquake struck within proximity of multiple countries. Panama and Costa Rica are both within 300km distance of its epicenter.

Located 107 kilometer (66 mi) south of the epicenter of this earthquake, Pedregal (Chiriquí, Panama) is the nearest significant population center. The intensity of shaking and damage in Pedregal is estimated to be around level IV on the Modified Mercalli Intensity scale (light shaking, likely no damage).

Multiple major population centers exist within 300km of the earthquake that struck today. Panamá is located 351 km to the east-northeast (intensity unknown, possibly low). San José is located 342 km to the northwest (intensity unknown, possibly low). San Miguelito is located 359 km to the east-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).

11 Aftershocks detected

This main shock was followed by 11 smaller aftershocks. At a distance of 43 km (27 mi) south of this earthquake, an aftershock struck 2 hrs later. It measured a magnitude of 4.2

Overview of foreshocks and aftershocks

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.

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 August 3rd, 2023, when a 5.9 magnitude earthquake hit 201 km (125 mi) further south. An even stronger magnitude 6.7 earthquake struck on October 20th, 2022.

In total, 16 earthquakes with a magnitude of 5.8 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 8 months.

Low tsunami risk

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.
