UNDERWATER ATOMIC BLAST 150 METER

Wahoo blast the test conditions were met on May 16 1958 allowing for the nuclear device to be detonated. Within a second of detonation, a spray dome was created that reached a height of 840 feet (260 m) after seven seconds. The overall shape of the spray dome resembled a cone with 45 degree sloped sides. Plumes were seen breaking through the spray dome after six seconds in every direction. The vertical plume continued rising until 12 seconds after the blast while the lateral plumes traveled for 20 seconds before collapsing.
