Earthquake Summary

The earthquake struck on land in Canada, 273 kilometer (170 mi) west of Whitehorse in Yukon. The center of this earthquake had a very shallow depth of 5 km. Shallow earthquakes usually have a larger impact than earthquakes deep in the earth.

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 2 thousand people exposed to shaking

This earthquake may have been felt by around 2 thousand 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.

The highest earthquake impact level for this earthquake is III, which corresponds with weak shaking and probably no damage. Roughly 340 people are expected to be exposed to this level. Intensity level II was experienced by the majority of people (around 2 thousand). In their region, very weak shaking and no damage can be expected. All exposure to shaking was within the borders of Canada .

Nearby towns and cities

This earthquake may have been felt in Canada . The closest significant population center near the earthquake is Whitehorse in Yukon, Canada. Whitehorse is located 273 kilometer (170 mi) west of the epicenter.

Overview of nearby places

This is likely an aftershock

Approximately 8 hrs before this earthquake hit, a larger 7 magnitude earthquake struck 34 km (21 mi) south-east of this one. For that reason, we classify the Mag. 5.0 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.

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 happen often in the region

Earthquakes of this strength are very common in the region. In total, 18 earthquakes with a magnitude of 5 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 7 months.

Tsunami very unlikely

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.
