California's Supershear Quake Threat: Faster and More Devastating Than Ever

California's Next Big One Could Be Faster and Far More Destructive A recent study by the Statewide California Earthquake Center at USC Dornsife warns that supershear earthquakes, which move faster than seismic waves, pose a significant threat to the state. These quakes can cause catastrophic shaking across California, and researchers are calling for stronger building standards and improved fault monitoring. Timeline of Key Events October 12, 2025: The study is published, highlighting the dangers of supershear earthquakes. Researchers from USC Dornsife have been studying earthquake patterns in California since 2018. Current construction standards do not account for the directional force of supershear quakes. Immediate Impact and Response The discovery has sparked concerns among residents and officials. "We need to take immediate action to prepare for these types of earthquakes," said Dr. Maria Rodriguez, lead researcher on the project. The California Department of Emergency Services is urging residents to review their emergency plans and ensure they are prepared for a potential supershear quake. Background Context Supershear quakes occur when an earthquake's rupture speed exceeds its seismic wave speed. This can cause widespread destruction, as buildings and infrastructure are not designed to withstand the intense shaking. The researchers found that many faults capable of magnitude 7 quakes might produce these explosive ruptures. What Happens Next The USC Dornsife team is working closely with state officials to develop new building codes and monitoring systems. "We need to be proactive in preparing for these types of earthquakes," said Dr. Rodriguez. The researchers are also advocating for increased funding for earthquake research and preparedness initiatives. As the threat of supershear quakes becomes more apparent, Californians must come together to ensure their safety and resilience in the face of this new challenge. *This story is developing.
