    • Coda wave attenuation in Mara Rosa seismic zone 

      schmidt, kellin; Ferreira, Vinicius; Vieira Barros, Lucas; Quintero, Ronnie (Sociedade Brasileira de Geofísica, 2013-08-26)
      Small local earthquakes from aftershock sequence in Mara Rosa, Goiás state, Brazil were used to estimate the coda wave attenuation in the frequency band of 1 to 20 Hz. The time-domain coda-decay method of a single ...
    • Parâmetros de fonte de sismos locais por inversão de formas de ondas 

      Zahradnik, Jiri; Vieira Barros, Lucas; Quintero, Ronnie (Sociedade Brasileira de Geofísica, 2010-11)
      The main purpose of this work is to invert seismic waveforms in order to obtain moment tensor for two medium size earthquakes detected by OVSICORI-UNA Costa Rica permanent seismic network, occurred in 2004, following the ...
