- An improved P-wave velocity reference model for Costa Rica Edi Kissling Ronnie Quintero Ciencias de la Tierra Merging travel time data wave velocity model for Costa Rica joint inversion hypocentral and velocity parameters We derive a P-wave 1D-velocity model for Costa Rica that may serve for routine high-precision earthquake location and asinitial reference model for 3D seismic tomography. The velocity inversions are performed using 822 well-locatable events togetherwith 14774 P-wave observations obtained by merging routine travel time data from 10 335 earthquakes in the period 1984to 1997 collected by the Universidad Nacional de Costa Rica (OVSICORI), and 3510 earthquakes in the period 1992 to 1998collected by the Red Sismológica Nacional (RSN) in Costa Rica. Special care is taken during the merging process to reduce thenumber of errors in the data and, in particular, to update, correct, and complete the station parameter list. Consistency and qualityare given priority over completeness of the resulting data set. The final data set for the period 1984 to 1998 in Costa Rica consistsof 11 848 local events with 13 2331 P-wave and 86 018 S-wave observations. 2001 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56840101 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.40
