Seismicity in colombian llanos foothills: Characterization, relocation and local seismic tomography

An earthquake relocation by seismic simultaneous inversion and double differences methods were done in the Colombian Llanos Foothills from 3º to 5ºN and from 73º to 75ºW. The data used in this work take account 483 earthquakes registered by The Colombia National Seismological Network (RSNC) between...
