Hayward Fault Line Overdue for Major Earthquake, Threatening Millions in California
Researchers have identified the Hayward Fault Line in California as overdue for a significant earthquake, potentially threatening millions of residents in the Bay Area. The fault, part of the larger San Andreas Fault system, extends 74 miles through densely populated areas such as Berkeley, Oakland, and Fremont. A study published in the journal Seismological Research Letters highlights the risk of a magnitude 7 earthquake, which could cause extensive damage. The last major event on this fault occurred in 1868, and scientists estimate a 14.3% chance of a 6.7 magnitude or larger event by 2034, increasing to 33% by 2043. The U.S. Geological Survey's 'HayWired Scenario' predicts that such an earthquake could result in 800 fatalities and 18,000 injuries. Researchers from Lawrence Livermore and Lawrence Berkeley National Laboratories have used 3D simulations to assess potential ground motion, aiming to inform infrastructure preparedness.
