- Crustal thickness beneath Rio de Janeiro, Brazil, from spectra of SH waves at station RDJ Felipe Dias Cario Jorge Luis de Souza Ciencias de la Tierra SH waves Rio de Janeiro S wave velocity crustal thickness southeastern Brazil Amplitude and phase spectra of long period analog S wave records were used to estimate crustal thickness under Rio deJaneiro seismic station. Earthquakes with shallow focal depths (10-33 km) and epicentral distances varying from 83 to 88degrees provided the best estimates of crustal thickness. Epicentral distance seems to be the most important parameter in gettingadequate amplitude and phase spectra. The estimated crustal thickness under RDJ station is 32.9 ± 2.6 km. This value iscompatible with an intraplate continent-ocean transition zone and with recent surface wave studies and crustal thicknessdeterminations from receiver functions. 2006 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56845203 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.45
