With the buildup of ice, and the power behind it, it has the potential to damage anything in its path." "The first slabs or sheets move on shore, creating a traffic jam, with ice piling on top and behind. The third condition is a gently sloping shoreline the gentler the slope, the less resistance the ice meets as it piles up and pushes inland." If strong winds then blow through the area, they can push the ice towards the water’s edge-and winds in the Lake Erie region were indeed quite powerful, reaching hurricane-like speeds of up to 74 miles per hour. The event is most common in springtime, when ice that covers large bodies of water starts to thaw, but has not yet melted. Ice "tsunamis tend to occur when three conditions are in place. Ice "tsunamis were being studied as far back as 1822, when an American naturalist commented on “rocks, on level ground, taking up a gradual line of march and overcoming every obstacle in.

Along the shores of Lake Erie, the gusts were so strong that blocks of ice surged over the shoreline and formed walls as high as 30 feet-a striking phenomenon known as an "ice tsunami"." More recently, a furious wind storm has been pummelling eastern Canada and United States, causing flight delays, school cancellations and thousands of power outages. ![]() Credit: Canadian Press Extra.Ī "polar vortex plunged much of the Midwest into dangerously frigid temperatures.
