Forward and Inverse Modeling of Tsunami Sediment Transport
… Hazard Events (STRICHE), which couples with GeoClaw and is referred to as GeoClaw-STRICHE. In an inverse model, deposit characteristics, such as grain-size distribution and thickness, are inputs to the model, and flow characteristics are outputs. We also depict one trial-and-error inverse …

Investigating Taphonomic Changes of Deposits and Modeling of the 2010 Earthquake and Tsunami in South-Central Chile
… and tsunami as a detailed case study. I used GeoClaw numerical modeling to compare simulated tsunamis from published co-seismic slip distributions of the earthquake with observations from post-tsunami surveys and modified these distributions to determine the most important tsunami-forming …

Modeling of Potential Historical Tsunamis from Large Earthquakes in the Izu-Bonin Mariana Subduction Zone
… been proven false. We use the tsunami model GeoClaw (v5.6.0) with adjoint-guided refinement level flagging to simulate IBM earthquakes in three separate segments to produce estimates of wave heights at locations around the Pacific Basin that have the potential for written records dating back …

The Automation of Numerical Models of Coseismic Tsunamis
… behaviors using the numerical modelling package, GeoClaw. The implementation of modeling could identify areas of interest for further study that are sensitive to fault failure geometry. Initial results show that by varying the geometry of sub-faults of a given earthquake, the resulting tsunami …

Assessing the Use of Tsunami Simulations as a Tool to Predict Source Magnitudes and Locations of Paleoearthquakes in Chile
… and inundation extent with the tsunami model GeoClaw for nine hypothetical tsunamigenic large earthquakes (M<sub>w</sub> 8.6, 8.8, and 9.0) in south-central Chile with epicenters at -35.1º, -38.8º, and -42.9º. As expected, increasing earthquake magnitude produced larger tsunami wave heights, …

Model Development and Monte-Carlo Methods for the Simulation and Analysis of Coastal Impacts of Barrier Island Breach During Hurricanes
… the mainland, we modified a storm surge model, GeoClaw, to impose a Gaussian bell-curve on the barrier island that opens during a hurricane simulation and deepened over time. We added a new method of generating storm surge with storm forcing inputs in the form of wind and pressure fields to …

Tsunami Excitation Estimation from Real-time GNSS
… Green’s functions generated with the GeoClaw shallow-water wave simulation software and maps seismic slip along each section of the fault to points located off the Cascadia coast in 20m of water depth and relies on the principle of the linearity in tsunami wave propagation. The system …

Mapping and Reconstructing the Paleotsunami Record in Queule, South-Central Chile
… of the 1960 tsunami in Queule using the GeoClaw finite-slip hydrodynamic model based on three published earthquake sources. The simulations showed inundation up to 4km inland that overtopped the coastal dunes; agreeing with historical documentation and testimonies of 1960 tsunami …

Defining historical earthquake rupture parameters and proposed slip distributions through tsunami modeling in south-central Chile
… hypothesized). For this research, I used GeoClaw, a numerical tsunami modeling code, to simulate 423 forward-modeled M<sub>w</sub> 8.7 - 9.5 earthquake scenarios with stochastic, variable slip distributions. I used Akaike’s Information Criterion (AIC) to identify significant earthquake …
