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 160 thousand people exposed to shaking

An estimated 160 thousand 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.

The highest earthquake impact level for this earthquake is III, which corresponds with weak shaking and probably no damage. Roughly 131,800 people are expected to be exposed to this level.

People in 4 countries have been exposed to shaking. In Guadeloupe , around 60 thousand people, with impact levels up to III (weak shaking, probably no damage). Roughly 50 thousand people were exposed to shaking in Dominica . Roughly 40 thousand people were exposed to shaking in Martinique .

Nearby towns and cities

9 countries can be found within 300km of the epicenter of this earthquake: Guadeloupe , Dominica , Martinique , Antigua and Barbuda and Montserrat . Futher away, this earthquake may also have been felt in Saint Lucia, Saint Kitts and Nevis and Barbados.

Le Moule in Guadeloupe, Guadeloupe is the nearest significant place from the epicenter. The earthquake occurred 192 kilometer (119 mi) east of Le Moule. The intensity of shaking and damage in Le Moule is estimated to be around level III on the Modified Mercalli Intensity scale (weak shaking, probably no damage).

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 8 people in 5 countries

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 8 people have reported shaking in 8 places in 5 countries (Guadeloupe, Antigua and Barbuda, Saint Kitts and Nevis, Martinique, Saint Lucia).We keep updating this article as more ground reports become available.

This is likely an aftershock

Approximately 16 mins before this earthquake hit, a larger 6.5 magnitude earthquake struck 3 km (2.1 mi) south-southwest of this one. For that reason, we classify the Mag. 6.0 earthquake as an 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.

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 are common in the region

Earthquakes of this strength occur quite regularly in the region. In total, 3 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

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.
