Here they find a strange ore which, when removed from contact with water, becomes highly explosive, and realize that this element, somehow working its way from deep in the Earth, is responsible for the earthquakes. Although the material is not analyzed for specific atomic traits, it is named Element 112 just because so far, 111 chemical elements had been discovered. A computer determines that in approximately one month, enough of Element 112 will emerge from the deep earth to cause the entire planet to explode. A desperate operation ensues worldwide to blast and trench the ground to let water in and cover Element 112, keeping it from drying out and expanding.The Night the World Exploded went into production with shooting locations at the Carlsbad Caverns in New Mexico the Iverson Movie Ranch in Chatsworth, California and the Databton Corporation Building in Pasadena, California.
