Japan's Meteorological Agency issued a rare warning, alerting citizens to an increased risk of a major earthquake. The warning comes after a magnitude 7.1 quake struck southern Japan, sparking concerns about the infamous "Big One". Experts predict a 70-80% chance of a magnitude 8 or 9 earthquake striking the Nankai Trough in the next 30 years, potentially causing trillions in damage and thousands of deaths.
