Global Coastal Risk Institute
The Tsunami Evaluation Institute (TEI) provides the world's most advanced framework for tsunami hazard modeling, coastal vulnerability assessments, and mitigation engineering.
Institutional Overview
Tsunamis represent one of the most powerful and unpredictable natural hazards on Earth. Unlike typical storm surges, a tsunami is a series of waves caused by the displacement of a large volume of water, typically in an ocean or a large lake. Earthquakes, volcanic eruptions, and other underwater explosions, landslides, glacier calvings, meteorite impacts, and other disturbances above or below water all have the potential to generate a tsunami.
At Tsunami.Eval, our mission is to transform raw seismic and bathymetric data into actionable intelligence for governments, NGOs, and coastal developers. We believe that coastal resilience is built on three unbreakable pillars: accurate Source Characterization, high-fidelity Propagation Modeling, and rigorous Vulnerability Analysis.
"To mitigate the global impact of tsunamis through the application of world-class fluid dynamics, high-resolution topographical mapping, and probabilistic risk evaluation. We aim to ensure that no coastal community is left without the data required to survive a major seismic event."
Our Expertise
Our hazard assessment begins with a deep dive into the geological history of a region. We characterize potential tsunami sourcesāfrom subduction zone megathrusts to local submarine landslides. By calculating the slip distribution and seafloor displacement, we define the initial conditions for our predictive models.
Using industry-leading codes like COMCOT and MOST, we simulate the propagation of waves across the deep ocean and their subsequent interaction with shallow-water bathymetry. Our models solve nonlinear shallow-water equations to predict inundation depth, run-up height, and flow velocity with surgical precision.
We evaluate how the built environment responds to hydrodynamic forces. By applying fragility curves and structural engineering principles, we identify vulnerable points in critical infrastructure, hospitals, and evacuation routes, providing a roadmap for reinforced coastal defense.
Probabilistic Tsunami Hazard Analysis (PTHA) is a sophisticated methodology used to quantify the likelihood of various tsunami intensities at a specific location over a given time period. Unlike deterministic approaches that model a single "worst-case scenario," PTHA considers a wide range of potential sources and their associated probabilities. This involves the integration of paleotsunami data, historical records, and synthetic earthquake catalogs.
The PTHA process begins with the identification of all possible tsunamigenic sources that could affect a site. For each source, a probability distribution is assigned to its rupture parameters (e.g., magnitude, slip, area). These parameters are then used to generate a suite of "source scenarios." For each scenario, numerical modeling is performed to determine the wave heights and inundation zones at the target site. Finally, these individual results are combined, weighted by their probabilities, to produce hazard curves and maps. This data is essential for insurance underwriting, urban planning, and the design of seawalls and vertical evacuation structures.
Advanced Mitigation
Evaluation is only useful if it leads to protection. Our mitigation strategy is built on the belief that data should drive infrastructure.
Coastal communities are increasingly at risk due to rising sea levels and intensified seismic activity. At TEI, we provide the technical blueprints for "TsunamiReady" certifications, ensuring that communities have redundant warning systems, clear evacuation signage, and practiced response protocols. We also specialize in the design of Nature-Based Solutions (NbS), such as mangrove reforestation and artificial reefs, which can significantly attenuate wave energy before it reaches the shoreline.
Reducing the uncertainty in tsunami hazard maps directly impacts the economic stability of coastal regions. When risk is poorly understood, insurance premiums skyrocket, and development becomes a gamble. By providing high-fidelity models, TEI enables insurers to price risk accurately and helps developers choose the most resilient sites for new infrastructure. Furthermore, our evaluations save lives by optimizing evacuation routesāensuring that every second counts when a warning is issued.
Beyond the immediate economic benefits, tsunami evaluation fosters a culture of preparedness. It transforms a fearful "unknown" into a manageable scientific challenge. When residents see the science behind the warning sirens and the carefully placed evacuation pillars, they are more likely to take timely action. This psychological readiness is the ultimate goal of our instituteāturning data into a shared social contract for survival.

"In the face of an incoming tsunami, data is more than just numbers on a screen; it is the voice of the ocean warning us to move. Our goal is to make that voice heard before it's too late."
As we look toward 2030, the Tsunami Evaluation Institute is investing in next-generation Global Navigation Satellite Systems (GNSS) to detect tsunamis via ionospheric disturbances and AI-driven predictive modeling that can account for multi-hazard scenarios, such as cascading failures of coastal seawalls. We are also expanding our outreach to ensure that every coastal resident understands the natural warning signs and knows their path to safety.
