A new version of CRISIS, the program to perform probabilistic seismic hazard analysis (PSHA), has been released. This new version, called R-CRISIS v20, includes several additions and improvements with respect to previous ones, in the geometric, attenuation and seismicity models, besides having implemented a parallelized computational process that speeds up the computations up to five times, adding flexibility to the users to perform state-of-the-art PSHA and more complex and detailed analyses within reasonable computational times. These additions have been implemented with the objective of having better representations of the different components of a PSHA whilst preserving all the options that were available in previous versions of the program. R-CRISIS remains being a free and open-source program, two characteristics that combined with its flexible programming architecture provide room for future developments of this mature and widely used tool.

已经发布了新版本的CRISIS，即用于执行概率地震危险性分析（PSHA）的程序。这个新版本称为R-CRISIS v20，除了在几何，衰减和地震模型中进行了一些添加和改进外，还实现了并行计算过程，可将计算速度提高五倍，从而增加了灵活性。用户可以在合理的计算时间内执行最新的PSHA和更复杂，更详细的分析。实施这些添加程序的目的是更好地表示PSHA的不同组件，同时保留程序以前版本中可用的所有选项。R-CRISIS仍然是一个免费的开源程序，
