What caused the Quebec blackout of 1989?
What caused the Quebec blackout of 1989?
The March 1989 geomagnetic storm occurred as part of severe to extreme solar storms during early to mid March 1989, the most notable being a geomagnetic storm that struck Earth on March 13. This geomagnetic storm caused a nine-hour outage of Hydro-Québec’s electricity transmission system.
What knocked out power in Eastern Canada in 1989?
On March 13, 1989 the entire province of Quebec, Canada suffered an electrical power blackout. Hundreds of blackouts occur in some part of North America every year. The Quebec Blackout was different, because this one was caused by a solar storm!
How long did the Québec blackout last?
12 hours
In less than 2 minutes, the entire Quebec power grid lost power.” The blackout lasted for 12 hours, and there were even impacts on satellites, as well as the Space Shuttle Discovery, which was in space to deliver a communication satellite into orbit.
How many people died in Quebec ice storm?
35 Canadians
Quebec turned into a crystal wonderland when freezing rain turned to ice, but that ice took down trees and power lines, depriving millions of electricity. The storm killed 35 Canadians, making it one of the worst natural disasters in Canadian history.
How likely is a solar flare to hit Earth?
The Indian researcher has quantified the likelihood of solar storms hitting the Earth. “Astrophysicists estimate the likelihood of a solar storm of sufficient strength to cause catastrophic disruption occurring within the next decade to be 1.6 – 12%,” the researcher wrote in the paper.
When did the power go out in Quebec?
On March 10, a strong wind left the Sun, heading for Earth. On March 12, the first voltage fluctuations were being seen on the Hydro-Québec transmission grid. The System Control Centre was doing what it could to maintain stability. However, on March 13 at 2:44 a.m., the Earth’s magnetic field was fluctuating violently.
Why was there a power blackout in Canada in 1989?
On March 13, 1989 the entire province of Quebec, Canada suffered an electrical power blackout. Hundreds of blackouts occur in some part of North America every year. The Quebec Blackout was different, because this one was caused by a solar storm! On Friday March 10, 1989 astronomers witnessed a powerful explosion on the sun.
Where did the power grid collapse in Quebec?
Seen as far south as Florida and Cuba, the vast majority of people in the Northern Hemisphere had never seen such a spectacle in recent memory. Electrical ground currents created by the magnetic storm found their way into the power grid of the Hydro-Quebec Power Authority and the entire Quebec power grid collapsed.
Why was there a geomagnetic storm in Quebec in 1989?
The variations in the Earth’s magnetic field also tripped circuit breakers on Hydro-Québec ‘s power grid. The utility’s very long transmission lines and the fact that most of Quebec sits on a large rock shield prevented current flowing through the earth, finding a less resistant path along the 735 kV power lines.
