Earthquake Summary

The earthquake struck on land in The United States, 40 miles (64 km) west of New York City in New York. The center of this earthquake had a very shallow depth of 2 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

Potential tsunami risk

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

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

Factor Under Sea? MAG-6.5 or stronger? Shallow depth?
Explanation Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake Not this earthquake.
This earthquake appears to have struck on land far from any coast.
Not this earthquake.
This earthquake had a magnitude of 4.8. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 2 mi (3 km). Earthquakes this shallow could trigger a tsunami.

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 69% likelyhood of between 0 and 1 fatalities, and a 98% 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 98% likelyhood of between 0 and 1 million US Dollars in economic damage and impact.

Roughly 43 million people exposed to shaking

An estimated 43 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.

An estimated 10,560 people were exposed to level VI. At this level, strong shaking and probably light damage can be expected. Intensity level III was experienced by the majority of people (around 22 million). In their region, weak shaking and probably no damage can be expected.

Nearby towns and cities

This earthquake may have been felt in The United States . Located 9 miles (14 km) northwest of the epicenter of this earthquake, Bridgewater (New Jersey, The United States) is the nearest significant population center. The intensity of shaking and damage in Bridgewater is estimated to be around level V on the Modified Mercalli Intensity scale (moderate shaking, very light damage).

Multiple major population centers exist within 300km of the earthquake that struck today. New York City is located 40 mi to the east and experienced an intensity of III (weak shaking, probably no damage). Brooklyn is located 43 mi to the east and experienced an intensity of IV (light shaking, likely no damage). Queens is located 48 mi to the east and experienced an intensity of IV (light shaking, 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).

Detected MAG2.5+ earthquakes within within 100km (62 mi), that occurred in the three days before and after the main shock.

More earthquakes coming?

Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.

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 4.8 or higher have been detected within 300 km (186 mi) of this epicenter.
