Meteotsunamis, an underrated hazard in the Great Lakes

A team of scientists led by the University of Wisconsin-Madison has found that small, 30 cm (1 foot), meteotsunamis happen more than 100 times per year on the Great Lakes, while larger ones of nearly 90 cm (3 feet) occur once per year on average. The timing of most...
