New AI model HypoNet Nankai PS improves earthquake hypocenter determination

By PulseAugur Editorial · [1 sources] ·

Researchers have developed HypoNet Nankai PS, an advancement of their previous HypoNet Nankai system, to more accurately and rapidly determine earthquake hypocenters. This new version incorporates both P- and S-wave travel times, utilizing a revised physics-informed neural network (PINN) training procedure to handle the steeper travel-time gradients of S-waves. When tested against synthetic earthquakes and real data from DONET stations, HypoNet Nankai PS demonstrated reduced root-mean-square deviations and provided hypocenter estimates consistent with existing catalogs, though some offshore locations differed significantly.
