A major upgrade to a key tool for real‑time earthquake analysis in Southern California is giving scientists faster, clearer insight into what faults may be involved when the ground starts shaking. Within minutes of an event, researchers can receive an automated email that includes an interactive 3D view showing the earthquake’s location relative to nearby fault structures. This new capability is part of a significant update to the Community Fault Model (CFM) Earthquake-to-Fault Association Service, which now operates on SCEC CFM version 7.0 and achieves a 90% association rate for magnitude 3.0+ events—up from 84% with the previous model.
