Texas A&M University at Galveston (TAMUG) Tsunami Research Group (TRG) is involved in the development of numerical tools for tsunami calculation. The TRG is led by Professor Juan Horrillo and investigator Alyssa Pampell from TAMUG. External collaborators are Professor Zygmunt Kowalik, University of Alaska Fairbanks (UAF); William R. Knight, West Coast & Alaska Tsunami Warning Center (WCATWC); Professor Yoshinori Shigihara, National Defense Academy of Japan; Yoshiki Yamazaki, University of Hawaii at Manoa (UH); Professor Alberto Lopez, University of Puerto Rico Mayaguez (UPRM), Professor Aurelio Mercado, UPRM and Professor Hermann Fritz, Georgia Institute of Technology .
The TRG has developed and been continuously improving a 3D numerical model based on the Navier-Stokes equations. The 3D model is mostly used for tsunami generated by submarine landslide. 3D model results is then coupled to a 2D non-hydrostatic model for wave propagation and detailed calculation of runup (inundation) in coastal areas. The 2D numerical model has been developed by the UAF and UH. Both models have been extensively validated and used for assessment of tsunami hazard, inundation, mapping and prediction of tsunami arrival time.
