Scientists are warning that major natural disasters, long considered theoretical or improbable, are increasingly inevitable for the United States. These potential catastrophes include a massive earthquake, an unusually powerful hurricane, and a severe volcanic eruption.
Researchers have identified "The Big One," a megaquake scenario, as a significant threat to California. Such an event would cause widespread devastation across the state in a matter of minutes.
Beyond earthquakes, the U.S. also faces the threat of extreme hurricanes. Scientists have conceptualized an "Ultra-Intense Category 6" storm, a hypothetical event that could unleash winds of 192 miles per hour or higher and cause sea levels to rise more than 25 feet. Porter Fox, author of a book on climate change and disasters, suggests such a storm could potentially impact New York City, with the Verrazano-Narrows Bridge being rattled by its force. 
Volcanic eruptions also pose a significant threat. Mount Rainier in Washington state is identified as one of the most dangerous volcanoes in the U.S. 
These warnings from scientists emphasize that while the exact timing is uncertain, the occurrence of these catastrophic natural disasters in the U.S. is considered a matter of when, not if.
