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 14 million people exposed to shaking

An estimated 14 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.

The highest earthquake impact level for this earthquake is V, which corresponds with moderate shaking and very light damage. Roughly 2,450 people are expected to be exposed to this level. Intensity level III was experienced by the majority of people (around 13 million). In their region, weak shaking and probably no damage can be expected. All exposure to shaking was within the borders of Canada .

People	MMI Level	Shaking	Damage
0	I	Not noticable	None
1,113,000	II	Very weak	None
13,050,000	III	Weak	Probably none
154,400	IV	Light	Likely none
2,450	V	Moderate	Very light
0	VI	Strong	Light
0	VII	Very Strong	Moderate
0	VIII	Severe	Moderate to heavy
0	IX	Violent	Heavy
0	X	Extreme	Very heavy

Nearby towns and cities

Canada and The United States are both located within 300km distance of the epicenter of the earthquake.

The closest significant population center near the earthquake is Orillia in Ontario, Canada. Orillia is located 25 kilometer (16 mi) east of the epicenter. The intensity of shaking and damage in Orillia 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. Toronto is located 105 km to the south-southwest and experienced an intensity of III (weak shaking, probably no damage). Mississauga is located 123 km to the south-southwest and experienced an intensity of III (weak shaking, probably no damage). Brampton is located 116 km to the south-southwest and experienced an intensity of III (weak shaking, probably no damage).

Risk of aftershocks?

We monitor for foreshocks or aftershocks that have a magnitude of 2.5+ and occur within 100km (62 mi) of the epicenter of this earthquake. So far no such earthquakes have been detected.

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.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this 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 4.1 or higher have been detected within 300 km (186 mi) of this epicenter.

Tsunami very unlikely

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.

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.

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 4.1. Earthquakes of this strength are unlikely to trigger a tsunami.	This earthquake occurred at a depth of of 12 km (7 mi). Earthquakes this shallow could trigger a tsunami.
