California’s tectonic systems at highest levels of stress in 1,000 years – study

A recent study reveals that California's San Andreas and San Jacinto fault systems are experiencing unprecedented tectonic stress, marking the highest levels in a millennium. This critically loaded state heightens the probability of a major earthquake in Southern California, often referred to as the "big one." Scientists warn that these elevated stress levels could lead to more frequent and potentially more devastating seismic activity, underscoring the urgent need for improved earthquake preparedness and infrastructure resilience. This insight is crucial as it highlights the heightened seismic risk and the potential impact on millions of residents.
