COMCOT version 1.7 (Cornell Multi-grid Coupled Tsunami model) is a highly specialized numerical modeling package used by researchers and government agencies to simulate the entire lifespan of a tsunami—from its initial generation at sea to its final inundation on the coast. Developed primarily by Xiaoming Wang and colleagues at Cornell University and later refined at GNS Science in New Zealand, the software has become a standard tool for disaster mitigation and academic study. Key Capabilities of COMCOT 1.7
Version 1.7 introduced significant technical improvements over its predecessors, making it more efficient and adaptable for large-scale simulations:
Nested Grid System: The software uses a multi-grid system (supporting up to 12 sub-level grids) that allows researchers to simulate broad transoceanic propagation at low resolution while using highly refined "nested" grids for detailed coastal run-up.
Hybrid Numerical Schemes: It solves shallow water equations in both Spherical and Cartesian coordinates. A key efficiency is its ability to use linear equations for deep ocean travel and nonlinear equations for shallow water where waves become more complex.
Multiple Generation Mechanisms: Beyond standard submarine earthquakes (using models like Okada 1985), version 1.7 can simulate tsunamis triggered by landslides, volcanic eruptions, or meteorite impacts.
Modernized Codebase: The transition from Fortran 77 to Fortran 90 allowed for dynamic memory allocation, making the program more expandable and the code cleaner. Practical Applications
Researchers use COMCOT 1.7 to reconstruct past catastrophes and predict future risks. For example, it has been used to model:
The 2004 Indian Ocean tsunami to study deposit patterns and inundation depths.
Worst-case scenarios for specific regions, such as predicting a 6.17-meter wave height in North Sulawesi following a hypothetical M8.5 earthquake.
The impact of the 2018 Mount Anak Krakatau flank collapse, helping authorities understand how landslide-triggered waves differ from seismic ones. Download and Documentation
