Abstract : Seismic waves generated by sources ranging from 2.7 kg shots of TNT to magnitude 5 earthquakes were studied in order to determine the seismic activity and crystal structure of the Orozco transform fault. Most of the data were collected by a network of 29 ocean bottom seismometers (OBS) and hydrophones (OBH) which were deployed as part of a project ROSE (Rivera Ocean Seismic Experiment). Additional information was provided by magnetic anomaly and bathymetric data collected during and prior to ROSE and by teleseismic earthquakes recorded by the WWSSN (Worldwide Seismic Station Network).
