tunguska event (by HanKFranK) excess trivia. not a weather event per se, but a rather tremendous atmospheric occurrence nonetheless on 30 june 1908. around dawn local time a speeding (~10000m/s) bolide meteor the size of a large house exploded several miles above the remote tunguska region in siberia. the shockwave leveled hundreds of square miles of boreal forest, and is estimated to have been equivalent to that of a 25 MT nuclear device. it could be heard as far away as london, and a measurable pressure wave signature circled the globe twice. i'll take a category 5 hurricane to that any day.
