The Tsunami Computational Portal (TCP) is made available as a service to researchers engaged in developing and comparing numerical models of tsunami generation, propagation, and inundation. It is intended for research purposes only.

Models are contributed to TCP by their original developers and will be undergoing further development; they may not be accurate or complete. Descriptions of the models are available from the "1.Model" tab. The models included in the current implementation are:

• COMCOT (Cornell Multi-grid Coupled Tsunami Model), developed by P.L-F. Liu, X. Wang, S-B. Woo, Y-S. Cho, and S.B. Yoon at the School of Civil and Environmental Engineering, Cornell University
• UAF Tsunami Model, developed by Zygmunt Kowalik and Elena Suleimani at the Institute of Marine Science (School of Fishery and Ocean Science) and Geophysical Institute, University of Alaska, Fairbanks

Additional models are being incorporated and should be available within a few month.

TCP also makes use of geospatial information that has been provided by independent groups. The data were collected or developed for the groups. own purposes, and may not be accurate or complete. All metadata provided by the contributing group is available from the "3. Sub Grids" tab. Current data includes:

• General Bathymetric Chart of the Oceans (GEBCO) 1-minute global bathymetric grid, http://www.ngdc.noaa.gov/mgg/gebco/
• ETOPO2v2 2-minute gridded global relief data, http://www.ngdc.noaa.gov/mgg/fliers/01mgg04.html
• NOAA Coastal Relief Model (CRM) 3-arcsecond gridded coastal bathymetric & topographic data, http://www.ngdc.noaa.gov/mgg/coastal/coastal.html
• NOAA combined bathymetric and topographic gridded data for Homer & Seward, AK [may be used within the TCP, but not distributed]
• UAF Geophysical Institute bathymetric data for Cook Inlet and Seldovia Regions of Alaska, http://www.gi.alaska.edu

Additional datasets were derived by combining GEBCO and NOAA CRM data, using the GMT mapping tools.
