Three fundamental steps are undertaken; Firstly, data on the seismogenic potential of faults in these areas are gathered, discussed and selected. The most likely fault rupturing mechanisms are discussed, which will lead us to focus the fieldwork on areas which are relevant to SHA but lack information on key seismic parameters (slip rates, segmentation, complex versus simple ruptures, maximum expected earthquakes, etc.). Secondly, the incorporation of that knowledge on seismogenic fault models into the SHA is conducted using existing Fault2SHA tools. This step includes the adaptation of those tools to these specific Latin American settings and the generation of new ones. Finally, results dissemination to society is ensured by the participation of stakeholders from civil protection, geological surveys and other end users through special meetings, training courses and on-line access that allow to keep track of progress and results.
