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 90% likelyhood of between 0 and 1 fatalities.

The USGS classifies the economic impact of this earthquake at level GREEN (low). They expect an 90% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 7.4 million people exposed to shaking

This earthquake may have been felt by around 7.4 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.

Light shaking and likely no damage may have been experienced by an estimated 1,257,000 people. At IV, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 6 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. Roughly 6 million people were exposed to shaking in Guatemala , with level IV (light shaking, likely no damage) as the highest recorded. In Mexico , around 1.4 million people.

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.

The closest significant population center near the earthquake is Tapachula in Chiapas, Mexico. Tapachula is located 117 kilometer (73 mi) southwest of the epicenter. The intensity of shaking and damage in Tapachula 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. Guatemala City is located 281 km to the east (intensity unknown, possibly low). Tuxtla is located 281 km to the north (intensity unknown, possibly low). Mixco is located 271 km to the east (intensity unknown, possibly low).

An overview of nearby towns and cities is available in the overview below. If places don't have intensity data available, it likely means the experienced impact in those places was fairly small.

Shaking reported by 2 people

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 2 people have reported shaking in 2 places in Guatemala.We keep updating this article as more ground reports become available. You may report that you felt this earthquake here.

Places with most reports:

• San Juan la Laguna, Sololá, Guatemala: 1 person.
• Santa Catarina Pinula, Guatemala, Guatemala: 1 person.

This is likely an aftershock

This earthquake is likely an aftershock of the MAG-7.3 earthquake that struck 31 mins earlier. That main earthquake hit 44 km (27 mi) north of the epicenter of this MAG-6.0 aftershock.

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.

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 are common in the region

Earthquakes of this strength occur quite regularly in the region. In total, 12 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 10 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.
