Aggregate results and analysis code for Geospatially Augmented Actuarial Modeling of Tsunami Loss: Building-Level Estimation, Portfolio Aggregation, and Reinsurance

This deposit provides aggregate numerical results and analysis code accompanying the manuscript "Geospatially Augmented Actuarial Modeling of Tsunami Loss: Building-Level Estimation, Portfolio Aggregation, and Reinsurance". The study assesses event-conditioned tsunami losses for 63,252 matched properties in Miyagi Prefecture, Japan, using the 2011 Tohoku tsunami footprint. The archive includes aggregate tables, portfolio-level sensitivity scenarios, analysis scripts, field definitions, provenance information, and verification tools. It does not contain building-level source records, individual property coordinates, or property-level exposure and loss estimates. Reproducing the building-level analyses requires lawful access to the source and intermediate datasets described in the README and manuscript; this aggregate package alone does not reproduce all analyses from raw data.
