What Happened on 13th march 1989 ??? On March 13, 1989the entire provinceof Quebec, Canadasuffered anelectrical powerblackout. Hundredsof blackouts occurin some part ofNorth Americaevery year.
What were the causes ?The geomagnetic storm causing this event was itself the result of a coronal mass ejection on March 9, 1989.Three and a half days later, at 2:44 am on March 13, 1989, a severe geomagnetic
Effects on Earth and People..Astronomers witnessed apowerful explosion on the sun.Within minutes, tangled magneticforces on the sun had released abillion-ton cloud of gas. It waslike the energy of thousands ofnuclear bombs exploding at thesame time. The storm cloud rushedout from the sun, straighttowards Earth, at a million miles
MORE DANGERThe solar flare thataccompanied theoutburst immediatelycaused short-waveradio interference,including the jammingof radio signals fromRadio Free Europe intoRussia. It was thoughtthat the signals hadbeen jammed by theKremlin, but it was only
Reports…Electrical ground currents createdby the magnetic storm found theirway into the power grid of theHydro-Quebec Power Authority andthe entire Quebec power gridcollapsed. Six million people wereaffected as they woke to find noelectricity to see them through acold Quebec wintry night. Thisstorm could easily have been a $6billion catastrophe affecting mostUS East Coast cities.
Blackout In QuebecThe variations in the earths magnetic field also tripped circuit breakers on Hydro- Québecs power grid. The utilitys 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.
