Just sitting here watching coverage of the poor Japanese, and wondered about this. Is there enough water in any of the great lakes to generate a tidal wave like what we have all seen on the news in japan. I live about 35 mile or so south of Lake Erie If a 8.9 quake happened in the middle or on the Canadian side of the lake would there be a resulting "tidal wave"? Now just so all the folks know, I understand that if a quake that size happened in Ohio a wave is the least of our worries since we are absolutely unprepared for such a thing! Nor am i worried about it I am simply curious, and I am always impressed with the amount of Knowledgeable people on here so I bet some one might KNOW.
