![]() ![]() Bell Island Boom, attributed to a lightning superbolt. ![]() Atmospheric ducting where distant thunder or other sounds are propagated across long distances due to travel through distinct atmospheric layers.Avalanches, either natural or human-made for avalanche control.Possible resonance from solar and/or earth magnetic activity inducing sounds.Underwater caves collapsing, and the air rapidly rising to the surface.The "booming" sound is heard only in a localized area around the epicenter. Shallow earthquakes can generate sound waves with little ground vibration.Military aircraft creating sonic booms (though this origin cannot explain occurrences before supersonic flight started).Explosive release of less volatile gases generated as limestone decays in underwater caves.This is plausible, since Cayuga Lake and Seneca Lake are two large and deep lakes. With lakes, bio gas from decaying vegetation trapped beneath the lake bottoms suddenly bursting forth.Gas escaping from vents in the Earth's surface.Meteors entering the atmosphere causing sonic booms.The solar wind's equivalent of a sonic boom can accelerate protons up to millions of miles per minute-as much as 40 percent of the speed of light. Coronal mass ejection CMEs often generate shock waves similar to what happens when an aircraft flies at a speed higher than the speed of sound in Earth's atmosphere ( sonic boom).Their origin has not been positively identified. James Fenimore Cooper, author of The Last of the Mohicans, wrote " The Lake Gun" in 1850, a short story describing the phenomenon heard at Seneca Lake, which seems to have popularized the terms. The terms "mistpouffers" and "Seneca guns" both originate in Seneca Lake, NY, and refer to the rumble of artillery fire. Early white settlers in North America were told by the native Haudenosaunee Iroquois that the booms were the sound of the Great Spirit continuing his work of shaping the earth. The booms occasionally cause shock waves that rattle plates. Those familiar with the sound of cannon fire say the sound is nearly identical. Their sound has been described as being like distant but inordinately loud thunder while no clouds are in the sky large enough to generate lightning. They have been reported from an Adriatic island in 1824 Western Australia, South Australia and Victoria in Australia Belgium frequently on calm summer days in the Bay of Fundy, Canada Lough Neagh in Northern Ireland Scotland Passamaquoddy Bay, New Brunswick Cedar Keys, Florida Franklinville, New York in 1896 and northern Georgia in the United States. elsewhere: " fog guns", " mistpouffers", " waterguns".United States: " Guns of the Seneca" around Seneca Lake and Cayuga Lake, Seneca guns in the Southeast US.Netherlands and Belgium: " mistpoeffers", " zeepoeffers", " zeedoffers", " mistbommen", " gonzen", " balken", " onderaardse geruchten".Japan: " uminari" (literally, "cries from the sea").Italy: " brontidi", " marina", " balza", " lagoni", " bomba", " rombo", " boato", " bonnito", " mugghio", " baturlio", " tromba", " rufa".,. ![]() ![]()
