The database contains stochastic tsunami scenarios used in the paper titled "A New Generation of Tsunami Inundation Maps for Chilean Cities: Tsunami Source Database and Probabilistic Hazard Analysis." To analyze the Chile-Perú subduction zone, it was divided into four seismic segments based on historical seismicity. Stochastic rupture scenarios were generated across a wide range of magnitudes, ranging from 8.0 to 9.6, using the Karhunen-Loeve expansion. Subsequently, the Stochastic Reduced Order Model (SROM) was applied to select representative tsunami scenarios for each seismic segment and magnitude range. The database offers three types of data: 1) Files containing fault parameters for use in the NEOWAVE model. 2) Figures displaying the slip distribution for each scenario, and 3) Probabilities associated with each scenario obtained through the SROM method. These probabilities are needed to generate probabilistic tsunami inundation maps using a weighted density function.
