Mega Disasters - Methane Explosion

Seizoen: 2 - Aflevering: 5 / 19 - Eerst uitgezonden: 02 oktober 2007 - Episode ID: 176231

Methane gas precipitates out of the Earth's crust but is easily diluted in the air and in the oceans. Yet, according to one scientist, certain oceanic conditions could trap the gas in regions with low water circulation and build up extreme pressure. Once these areas are disturbed, the gas would blow out of the ocean in powerful jets. If they ignited before diluting, the explosion could cause widespread devastation. The scientist also posits that a similar event caused the Permian extinction.
