ITACA REXEL-disaggregation-values Web-Service

The ITACA REXEL-disaggregation-values web-service provides the results of hazard disaggregation for 10,760 sites in Italy (reference grid of the Italian seismic code NTC08 - CS.LL.PP. 2008) in terms of a modal terne of joint distribution of magnitudes (M), Joyner-Boore distances (R) and standardized residuals (ε) that are conditioned to a given threshold value of the parameters computed according Probabilistic Seismic Hazard Analysis. The disaggregation parameters for first and second mode are returned for a given set of ground motion parameters e.g. PGA and elastic pseudo-acceleration response spectrum (5% damped) at several vibration periods SA(0.5s), SA(1s), SA(1.5s) and return periods 50, 475, 975, 2475 years.

Feature Notes

• The output is given in terms of M range (i.e. min_magnitude, max_magnitude that are computed as ±0.5 units centered in the modal value), R range (i.e. min_distance_km, max_distance_km that are computed as ±10 km centered in the modal value) and the modal value of ε.
• Latitude and Longitude of sites outside Italy are invalid options
• The output data are provided in a JSON file
