Reliable Technical Support for Geoscience Professionals and Firms

Profile Summary

Hernán Porras holds an M.Sc. in Geology and a Ph.D. in Marine Sciences. He has more than 15 years of experience in geological and oceanographic research across Latin America and the Caribbean. His academic background is complemented by applied work with national seismic networks, civil protection agencies, UNESCO/IOC, and educational institutions. Previous and ongoing projects include: Simulation of tsunamis and coastal flooding in Puerto Rico, Jamaica, and Costa Rica. Structural and tectonic analysis of the Central American forearc and the Caribbean margin. GNSS-based deformation modeling in tectonically active regions. Integration of terrain and seabed data to study turbidity, run-up, and slope dynamics. Use of remote sensing to analyze coastal change, land cover, and marine hazard exposure. With experience in field campaigns and advanced modeling, Hernán combines hands-on geoscience expertise with cutting-edge data processing and visualization techniques. On-Demand Services: 1. Structural Geology and Tectonics Kinematic modeling and subduction zone analysis Interpretation of 2D seismic lines and structural cross-sections Fault maps, geological profiles, and structural style analysis 2. Geophysical and GNSS Data Processing Crustal deformation analysis (GNSS time series, velocities, vectors) Estimation of shortening rates, displacement, and subsidence Visualization of geodetic networks and deformation fields 3. Numerical Modeling and Coastal Hydrodynamics Tsunami simulation using Tsunami-HySEA or COMMIT Run-up maps, arrival times, flow velocities, and flood extents Variable friction modeling and complex bathymetric scenarios 4. Applied Physical Oceanography Turbidity, current, slope, and bathymetric analysis Processing of multispectral data, satellite imagery, and in situ sensors Time series analysis, buoy data validation, and hydrodynamic modeling 5.
