"IF THE SAN ANDREAS FAULT UNZIPS, WE CAN HAVE VOLCANOES ACTIVATE ALL THE WAY FROM MEXICO TO ALASKA." Anthony W. Soule, Volcanologist During WWII security shelters were built several floors beneath government buildings. Airplanes shattered our world on September 11, 2001 necessitating an immediate update. To this end an underground city is built in Mt. Eisenhower, near Banff, Canada. This emergency safe haven, built with Black Budget funds, is being inspected by Drs. Acel Parker and Tony Soule, both USGS volcanologists, when a Southern California volcano erupts. Construction nearly complete, this emergency forces the shelter to be opened immediately. Sensors, alarms and cameras focused from all angles, did not alert personnel in time to warn the public. No, it wasn't Mt. Saint Helens. Nor Yellowstone. It was Mammoth Mountain, the long smoldering 11,000 foot peak that drew 1.5 million skiers in the 2005-2006 season in Yosemite National Park. The deadly carbon dioxide gas would be pushed thousands of miles by the jet stream. What extreme anger made computer mastermind Harper Holbrook disable the eruption alert sensors? Panic rages from California to Canada when word is broadcast by television and radio that carbon dioxide gas is spreading across the United States. A search to apprehend the non-descript villain leads to a nuclear waste repository in the Yucca Valley, Nevada wilderness.
