![]() "Magnitude 3 quite common around here in the Great Lakes."Īs a result, scientists suspect ancient fault lines likely exist under all the Great Lakes, but they remain almost entirely unknown and unmapped. However, minor earthquakes in Ontario aren't anything out of the ordinary, said Alexander Peace, a structural geologist at McMaster University in Hamilton. Ontario sees fewer and less serious earthquakes than places on plate boundaries, like Turkey, shown here after a 7.8 magnitude quake struck parts of the country earlier this month. This is why we see fewer and less serious earthquakes than places on plate boundaries, like B.C. Most Ontario residents have likely never felt an earthquake because while dozens of seismic events occur each year, only a handful reach a magnitude that can be felt.įault systems (the most common place for stress in the planet's crust to be released) around the Great Lakes are relatively inactive, according to experts. Why earthquakes in Ontario are less intense The research indicates some promising results in other locations, but scientists say more needs to be done to understand that correlation, and earthquakes in the Great Lakes area. Now, scientists are investigating whether natural water level fluctuations - such as those brought on by climate change - correlate with regional seismic activity. Several survivors rescued over a week after earthquake in TurkeyĮarthquakes, especially major ones, are caused by movement of tectonic plates, and scientists are constantly investigating the many factors that can lead to local seismic activity.Ĭontributing factors include human activities such as mining, the injection of wastewater underground, and dam reservoirs that experience rapid and intense fluctuations in water level.4.2 magnitude earthquake near Buffalo, N.Y., felt in southern Ontario.The death toll has surpassed 40,000.īut while earthquakes in Ontario do not typically cause loss of life, they're more common than you might think, say scientists. In another part of the world the same day, an unrelated, devastating 7.8 magnitude earthquake hit Turkey and Syria. ![]() 6.Įarthquakes Canada monitored the magnitude 4.3 quake and said there were no reports of damage. Catharines, Ont., resident Stephen Murdoch told CBC Hamilton the morning of Feb. "I woke up to it … I felt what I guess you would consider a small jolt and continuous shaking … about 15 to 20 seconds," St. Darius Mahdavi, a scientist with a degree in conservation biology and immunology and a minor in environmental biology from the University of Toronto, explains how issues related to climate change affect people, and explores solutions, especially in smaller cities and communities.Įarlier this month, parts of southern Ontario felt an earthquake that struck close to the nearby city of Buffalo, N.Y. The Great Lakes Climate Change Project is a joint initiative between CBC's Ontario stations to explore climate change from a provincial lens.
