CRISIS Non-Poissonian seismicity model
Shweta Bajaj posted this 27 June 2019 - Last edited 27 June 2019

For Non-Poissonian seismicity model, Crisis is using the probabilities to compute seismic hazard. I would like to know what formulations Crisis is using to compute the hazard using probabilities instead of annual exceedance rates? I looked into the manual of Crisis but I didn't find anything related to the formulations for non-Poissonian seismicity models.

CRISIS Return periods assessed in logic tree calculations

Dear Nikos,

Indeed, to export a hazard map you choose a exceedance probability in a time frame (e.g. 50 years) and automatically R-CRISIS calculates the return period associated to those values. However, some users are interested in getting the .map output file, which contains uniform hazard spectra for selected hazard levels. In this way, you will obtain a file in which the UHS, for each return period defined, will be contained.

Remember, to obtain this file you have to check the .map option in Input -> Set output files (optional).

 

Thank you for your preference and interest in R-CRISIS.

 

 

Best regards,
