Empirical and numerical models of sudden gas releases (e.g., limnic eruptions like Lake Nyos, 1986) suggest that such an event could generate initial wave heights of 30 to 100+ feet (9–30+ meters) near the source.
And yet we have no reports of waves accompanying these Booms.
Seneca is the very definition of a small lake. It is 38 miles long and 3 miles at its widest. People build their homes right at the edge of the water, just a foot or two above the water.
People would have noticed a 30 foot wave.
Correct. Which is why I posited that before looking further into the possibilities.
