Scientists Discover Hidden Massive Earthquake Threat

Scientists have identified the previously overlooked Tintina Fault beneath North America as a significant seismic threat, potentially capable of producing a magnitude 7.5 or greater earthquake, which could impact communities and infrastructure across Alaska and Canada.
