Potential Tsunami Risk

There is a potential tsunami risk in the aftermath of this earthquake, immediately evacuate to higher grounds away from coastal areas and monitor advice from local authorities. This earthquake checks all the likely tsunami risk factors: under sea, at a magnitude of MAG-6.5+ and at a shallow depth.

Tsunami Risk Factors

Significant impact predicted

Based on scientific estimates by the US Geographic Survey (USGS), the risk of high fatalities for this earthquake is classified at level YELLOW (significant). They expect an 40% likelyhood of between 10 and 100 fatalities, and a 95% chance that the number of fatalities falls no higher than 1,000.

The USGS classifies the economic impact of this earthquake at level YELLOW (significant). They expect an 35% likelyhood of between 10 and 100 million US Dollars in economic damage and impact, and a 91% chance that the economic impact of this earthquake falls between 1 and 10,000 million USD.

Roughly 37 million people exposed to shaking

An estimated 37 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.

Very strong shaking and likely moderate damage may have been experienced by an estimated 66,990 people. At VII, it is the highest MMI level this earthquake has caused. The majority of people (roughly 23 million) live in an area exposed to level IV, where light shaking and likely no damage is expected.

People in 5 countries have been exposed to shaking. Roughly 13 million people were exposed to shaking in Mexico , with level VII (very strong shaking, likely moderate damage) as the highest recorded. In Guatemala , around 19 million people. In El Salvador , around 4.8 million people. Other countries where people were exposed to shaking include Honduras and Belize.

Nearby towns and cities

This earthquake struck within proximity of multiple countries. Mexico and Guatemala are both within 300km distance of its epicenter. Futher away, this earthquake may also have been felt in El Salvador, Honduras, Belize and Nicaragua.

Huixtla in Chiapas, Mexico is the nearest significant place from the epicenter. The earthquake occurred 79 kilometer (49 mi) southwest of Huixtla. The intensity of shaking and damage in Huixtla is estimated to be around level VI on the Modified Mercalli Intensity scale (strong shaking, probably light damage).

Multiple large cities are in proximity of today's earthquake. Guatemala City is located 262 km to the east and experienced an intensity of IV (light shaking, likely no damage). Tapachula is located 82 km to the north-east and experienced an intensity of V (moderate shaking, very light damage). Tuxtla is located 240 km to the north and experienced an intensity of IV (light shaking, likely no damage).

The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

29 Aftershocks detected

Since this main shock, 29 smaller aftershocks were detected. Just 31 mins after this main shock, an earthquake measuring MAG-6 was detected 44 km (27 mi) south of this earthquake.

This main shock was prefaced by 6 smaller foreshocks. A 4.7 magnitude earthquake hit 1 hr earlier nearby.

Overview of foreshocks and aftershocks

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

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 9 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 8th, 2017, when a 8.2 magnitude earthquake hit 112 km (70 mi) further northwest. That was also the heaviest earthquake to hit the region in the past 10 years.

In total, 1 earthquake with a magnitude of 7.3 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.
