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. The US Geographic Survey organization has indicated a potential risk for tsunami's following this earthquake.

Tsunami Risk Factors

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 190 thousand people exposed to shaking

An estimated 190 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 IV, which corresponds with light shaking and likely no damage. Roughly 63,640 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 130 thousand). In their region, weak shaking and probably no damage can be expected.

People in 4 countries have been exposed to shaking. In Guadeloupe , around 80 thousand people, with impact levels up to IV (light shaking, likely no damage). In Martinique , around 60 thousand people. Roughly 60 thousand people were exposed to shaking in Dominica .

Nearby towns and cities

This earthquake struck within proximity of multiple countries. Guadeloupe , Dominica , Martinique , Antigua and Barbuda and Montserrat are all within 300km distance of its epicenter. Futher away, this earthquake may also have been felt in Saint Lucia, Saint Kitts and Nevis, Barbados, Anguilla and Saint Vincent and the Grenadines.

Le Moule in Guadeloupe, Guadeloupe is the nearest significant place from the epicenter. The earthquake occurred 190 kilometer (118 mi) east of Le Moule. Le Moule experienced an earthquake intensity (MMI Scale) of roughly IV. That level implies light shaking and likely no damage.

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).

32 Aftershocks detected

This main shock was followed by 32 smaller aftershocks. At a distance of 5 km (3 mi) east of this earthquake, an aftershock struck 16 mins later. It measured a magnitude of 6

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.

This is an unusually powerful earthquake

No earthquake of this strength has struck this region for a long time. Our data goes back 10 years, and no earthquakes measuring a magnitude of 6.5 or higher have been detected within 300 km (186 mi) of this epicenter.
