Crustal velocity structure of southern Guatemala using refracted and Sp converted waves

The crustal velocity structure of southern Guatemala is estimated using the methods of Minimum Apparent Velocity and Converted Waves, applied to local seismic data. The results are tested by relocating a random sample of events and by the generation of synthetic seismograms. The velocity model obtai...

Descripción
Sumario:The crustal velocity structure of southern Guatemala is estimated using the methods of Minimum Apparent Velocity and Converted Waves, applied to local seismic data. The results are tested by relocating a random sample of events and by the generation of synthetic seismograms. The velocity model obtained has a roughly constant gradient throughout the crust, underlain by an intermediate layer - 15 km in thickness. Mantle velocities are approximately 8.0 km/sec. This is an average model for southern Guatemala with the limitations of the complex tectonics.
