Crustal structure along the southern Central American volcanic front
(American Geophysical Union, 2008-08-20)Subduction alters continents several ways, including accretion, magmatic addition, mantle wedge serpentinization, and crustal differentiation. These changes affect seismic velocities, so characterizing upper plate crust ... -
Crustal Velocity Anomalies in Costa Rica from Ambient Noise Tomography
(Springer Nature, 2019-08-24)We derive group velocity maps for crustal Rayleigh waves across Costa Rica and corresponding 3-D shear-wave velocity structure from ambient noise cross-correlations between 56 seismic broadband stations. The daily inter-station ...
