00:00Scientists are issuing urgent new warnings about a hidden earthquake threat building beneath five western U.S. states.
00:06And the timeline is shorter than many Americans realize.
00:10New seismological data from the U.S. Geological Survey shows increased strain accumulation
00:16along multiple fault systems in California, Oregon, Washington, Nevada, and Utah.
00:22The Hayward Fault, running directly beneath Oakland and the East Bay,
00:26home to more than 3 million people, has not ruptured in 156 years.
00:31It is considered overdue.
00:33Meanwhile, the San Andreas Fault in Southern California is building pressure
00:38at a rate that leads scientists to estimate a major rupture.
00:42What geologists call the big one is more likely now than at any point in the past century.
00:48A magnitude 7.0 or greater quake along the Hayward or San Andreas Faults
00:54would cause catastrophic structural damage across California,
00:58knock out critical infrastructure,
01:00and potentially trigger fires in dozens of urban neighborhoods simultaneously.
01:04FEMA recommends every household in the western U.S.
01:08have 72 hours of emergency supplies, water, food, medication stored and ready.
01:14These faults are not going away.
01:16The pressure keeps building.
01:18And America's western cities need to be ready.
