| Sumario: | Tsunami records registered during the October 9, 1995 Jalisco-Colima earthquake (Mw 8) by two tide gauges and onepressure gauge are analyzed to estimate the coseismic subsidence at Manzanillo and Navidad Bay. Numerical modeling of thetsunami waveform determined the location and magnitude of the maximum coseismic uplift on the fault plane. To fit the observeddata, the fault slip offshore from Manzanillo is required to be 2-3 times smaller than the average slip on the fault plane off NavidadBay. The new constraints on the coseismic uplift distribution obtained combined with the existing coseismic inland GPS datashould accomplish a new more detailed inversion of the fault-slip distribution. |
