Tsunamis on the Great Lakes
We usually associate tsunamis with the Pacific Ocean and the Ring of Fire. There have been records of tsunamis on all the other oceans, and the seas. The Great Lakes, never, but like all
large bodies of water they are
capable of and have had tsunamis. This may come as a surprise to some people, but they have been documented many times. The best documented tsunamis are on Lake Ontario, but undoubtedly there have been others on the Great Lakes.
On April 25, 1854 which was otherwise calm the lake in front of Niagara-on-the Lake suddenly receded some 500 feet from the shore. This was followed by s series of huge waves that were about 8 feet high. These giant waves wrecked shore installations, and drowned two fishermen that were caught in them. The waves also brought up great quantities of trees and other flotsam that was deposited along the shore. The tsunami was carried in newspaper accounts by the Niagara Mail and the Canadian Journal. There are sudden changes in the lake levels brought about by strong winds that will pile up the water in front of them called "seiches." This possibility was discussed, but discarded as there were no high winds on that day.

Earthquake in Canada rattles upstate NY, Vt.
June 23, 2010
ALBANY, N.Y.—An earthquake centered in Canada was strong enough to rattle furniture across the state and was felt as far south as New York City.
The quake was felt as far away as Michigan and Vermont. In New York, it prompted several calls to state police in Ray Brook in the Adirondacks.
"My dog picked his head up just before it happened and kind of looked at me," said Kellie Tassone, who was at her at home on Oneida Lake in the Syracuse area. Then the sliding door started to rattle "and the house was shaking."
