Barisal Guns

Barisal Guns, mysterious sounds, as of distant cannon, heard in many parts of the world, especially on or near the water, now generally believed to be caused by earth tremors that are too feeble to be felt. This phenomenon is known scientifically as brontides and commonly as Barisal guns because it is particularly prevalent near the city of Barisal in Bangladesh. The sounds have various other names in different countries; in the Netherlands and Belgium they are known as mistpoeffers, in Italy as baturlio marina, or brontidi, and in Haiti as gouffre. In the United States, on Seneca Lake, New York, they are called lake guns.
