Simulation data for a semi-empirical approach for tsunami inundation in South Italy
<p>The archive contains data used for the simulations devised for a semi-empirical method for the evaluation of tsunami wave propagation and inundation along the coasts of South Italy.</p> <p>UPDATE - October 19, 2022<br> - Added readme files (in English and Italian) with an explanation of the files of the repository.<br> - Added text files for values of alpha also for the case of perpendicular tsunami fronts (as per Figures 5d and 5f of the paper); only files for realistic tsunami fronts (as per Figures 5c and 5e of the paper) were present in the previous version of the repository. </p>
2010 Mentawai Tsunami Earthquake Simulations
<p>This dataset includes rupture models and associated waveforms of the 2010 M7.8 Mentawai, Indonesia tsunami earthquake. The simulations were generated using codes from https://github.com/UO-Geophysics/MudPy.</p> <p><strong>Test_simulations</strong> contains simulations for the initial tests individually varying the rise time, rupture velocity (Vrupt) and stress-drop (Figs. 5-7 in the accompanying publication).</p> <p><strong>GPR_simulations </strong>contains simulations for the Gaussian process regression analysis. These are separated into strong-motion waveforms for the 1D analysis with varying stress drop and HR-GNSS waveforms for the 2D analysis with varying rise time and Vrupt (Fig. 8 in the accompanying publication).</p> <p><strong>TsE_simulations</strong> contains the final datatset generated using recomended tsunami earthquake parameters (Table 1 and Fig. 9 in the accompanying publication). </p> <p>For the GNSS waveforms, files within <strong>GNSS_raw</strong> are the raw GNSS waveforms without noise, and files within <strong>GNSS_noisy</strong> are the raw waveforms with real noise added. No noise was added to the strong motion waveforms.</p> <p>The .log and .rupt files within the /ruptures/ subdirectories are standard files generated from MudPy. The .log files are summaries of each rupture, and the .rupt files are the full rupture kinematics of each rupture including slip information for the individual subfaults.</p> <p>Details on how the ruptures and data were generated are available in the following publication:</p> <p>Nye, T. A., Sahakian, V. J., & Melgar, D. (2024). Validation of tsunami earthquake ground-motion simulations using near-field observational data: Rupture parameter constraints from the 2010 Mentawai event.

Tsunami simulations
<p>6 simulations for Senseiver experiments on tsunami waves. The files starting with "agg" we used as testing data, the files starting with "unseen" are test data. The files ending with "_as" may be used for experiments with artifical sensors. The files ending with "_145" indicate tsunami simulations from 0 - 2 hours, and ending with "_289" indicate tsunami simulations from 2 - 4 hours.</p>
