AGUILAR-MELENDEZ, Armando et al. Development and Validation of Software CRISIS to Perform Probabilistic Seismic Hazard Assessment with Emphasis on the Recent CRISIS2015. Comp. y Sist. [online]. 2017, vol.21, n.1, pp.67-90. ISSN 1405-5546.

The probabilistic seismic hazard assessment (PSHA) is a fundamental step to generate information that can contribute to reduce the seismic risk in cities. This reduction is essential to increase the resilience of the cities. Nowadays, there are different types of software that can be used to perform PSHA. In the present document a recent version of the CRISIS software to perform PSHA is described. CRISIS2015 is a versatile tool to perform PSHA. The first version of CRISIS was done more than fifteen years ago. In order to highlight the progress of CRISIS since then, in the present document some comparison between features of the recent CRISIS2015 and earlier versions are included. Additionally, different versions of CRISIS have been tested according to different validation procedures. In the present document results of tests that were applied to an earlier version of CRISIS2015 and also that were applied to the recent CRISIS2015 are included. According to the results of different tests, it is possible to conclude that the recent CRISIS2015 can compute PSHA with high precision. CRISIS2015 was included in an international project to validate software to compute seismic hazard. Representative results of this validation project are included in this document. The results computed by CRISIS2015 are in total agreement with the results considered as valid in the recent edition 2014-2015 of the PEER project to validate software to compute seismic hazard. Finally, examples of the kind of projects where some version of CRISIS has been applied to perform PSHA in the last fifteen years are included.
