Coda wave attenuation in Mara Rosa seismic zone
(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
(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 ... -
Combined GPS, EDM and triangulation surveys of the rapid downslope motion of the western flank of Arenal Volcano, Costa Rica
(2011)Here we present initial conclusions of a one year-long combined geodesy campaign on Arenal Volcano, in Costa Rica (2008-2009). Our data shows evidence for an active local tectonic surrounding, and a 7cm/yr displacement ... -
The Nicoya segment of Middle American Trench: an Excellent Target for Drilling and Monitoring the Shallow Portion of the Seismogenic Zone
(2011-06-28)The Nicoya segment of Middle America Trench has generated large earthquakes in 1883, 1900 and 1950. Since the Nicoya peninsula sits right over the seismogenic zone, it has proved to be a unique site for near field monitoring ... -
