Geophysical, geochemical and geodetical signals of reawakening at Turrialba volcano (Costa Rica) after almost 150 years of quiescence
(Elsevier, 2010-11)
Turrialba is a basaltic–andesitic stratovolcano (3340 masl), in the Cordillera Volcánica Central in Costa Rica. After the last eruption (1864–1866), volcanic manifestations were limited to weak fumarolic discharge (continuous ...
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 ...
Constraints on upper mantle anisotropy surrounding the Cocos slab from SK(K)S splitting
(American Geophysical Union, 2010-06-24)
SKS and SKKS splitting observations are used to constrain the pattern of mantle flow
in the Central American subduction zone beneath Costa Rica and Nicaragua. After
removing the effects of shallow wedge anisotropy on ...
