1. Estudoda sismicidade na região de Sobral - CE em 2008
The town of Sobral is located at the northwest part of the Ceará State, 250 km away from its capital, Fortaleza. In January 2008, an intense seismic activity began near Sobral with one event with magnitude 4,2mb on May 21. Since the start of its seismic activity, all events were recorded by the SBBR station (located on EMBRAPA Caprinos Farm), which operates

2. Estudo da atividade sísmica em São Caetano-PE em 2007
Nesta dissertação foi estudada a atividade sísmica no município de São Caetano, estado de Pernambuco, Nordeste brasileiro, localizado próximo ao Lineamento Pernambuco. O Lineamento Pernambuco é uma zona de cisalhamento Neoproterozóica de escala continental que deforma a província Borborema. A sismicidade estudada ocorreu numa ramificação para nord

3. Seismic tomography with P- and S-waves for the study of the upper mantle in Brazil / Tomografia sísmica com ondas P e S para o estudo do manto superior no Brasil
We used travel time seismic tomography to study the upper mantle beneath SE and Central Brazil. This method is based on the inversion of P- and S-wave relative travel time residuals (VanDecar, 1991) obtained from more than 80 stations in an area of 20 x 20 degrees. More than 11000 P and PKP residuals, and more than 8000 S, ScS, SKS, and SKKS residuals were o

4. Should standard building structures in Brazil be guaranteed by a seismic resistant design?
Brazilian territory is situated on an intraplate region with low seismic activity, and so, it is important to answer an old question that remains unanswered: "Should standard building structures in Brazil be guaranteed by a seismic resistant design?" In this way , a methodology is described and used to evaluate the annual failure probability of a structure m
