| contents | Pn-wave observations in Costa Rica Ota Kulhánek Ronnie Quintero Ciencias de la Tierra Vp Time Vs ratio anisotropy Costa Rica P- and S-wave arrival-time data from 100 local and regional earthquakes recorded by the OVSICORI-UNA Costa Rica seismographicnetwork, between 1984 to1990, are employed to extract crustal and upper mantle information beneath Costa Rica. Pn-wavevelocity, Poissons ratio, velocity anisotropy and station corrections were calculated in this study. Poissons ratio for the uppermostmantle beneath Costa Rica is 0.265 and the Pn velocity is 7.81 km/sec. The present study does not reveal any significant Pn velocityanisotropy. The computed Moho depth beneath Costa Rica is approximately 34 km. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837303 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.37 |
