  1. SEISMOLOGY AT IAG-USP IAG: Inst. Astronomy, Geophysics & Atmospheric Sciences USP: University of São Paulo

  2. Main Research Areas Brazilian seismicity: Crustal and upper mantle structure • Natural and dam-induced • Seismic risk • - Crustal stresses • deep seismic refraction • receiver functions • - upper mantle tomography Cooperation with Carnegie Institute, USGS-Menlo Park Northwestern University, Montpellier (France), Univ. S. Carolina, Barcelona, Potsdam
