New algorithm produces sharper images of earthquake locations on California faults
In short: Researchers developed a new computational method to pinpoint exactly where earthquakes occur. By using the differences in arrival times between P-waves and S-waves, the algorithm allows scientists to locate seismic events with much higher precision than previous catalog methods, even when dealing with complex underground structures.
This technique works by minimizing errors caused by unmodeled velocity structures in the Earth's crust. When applied to the northern Hayward fault in California, the method transformed blurry earthquake data into sharp images of seismicity, revealing narrow horizontal lines where stress is released through brittle failure.
The study was performed using a computational algorithm applied to earthquake clusters, though its effectiveness depends on the quality of available cross-correlation data.
Why it matters: This method allows geologists to see the precise structure of fault zones more clearly.
