Bayesian Analysis of Paleotsunami Sources: Data and Stochastic Simulations

This repository contains the datasets utilized in the research titled “Tracing the Sources of Paleotsunamis Using Bayesian Frameworks.” Each dataset is integral to the analysis and reconstruction efforts undertaken in the study.

File Descriptions

1. CorrectedShoreline_jogan_deposit_data.csv

This file contains paleotsunami data collected by Sugawara et al. The data has been corrected to account for the shoreline position at the time of the paleotsunami event.

2. Stochastic_samples.zip

This archive contains the stochastic samples generated for the Japan Trench, utilizing the coupling distribution model from Loveless et al.

3. Selected_Stochastic_Samples.zip

This file includes a reduced sample space derived from the original stochastic samples, specifically selected for statistical analysis.

4. Sendai_1961.zip

This dataset contains the reconstructed morphology of the Sendai plain as it appeared in 1961. The reconstruction is based on aerial photographs provided by the Geospatial Information Authority of Japan (GSI).
