Seismic Hazard results are shown in Hazard -> See Hazard Maps menu. There, you can export such Hazard Maps in different formats: Bitmap, XYZ file, Bing Maps or Surfer 6.0 DSBB. To export a map to a GIS application format, you have to follow these instructions once you are inside Hazard -> See Hazard Maps menu:

1. Click on Save Map icon

2. Select path where you want to save yours maps

CRISIS Defining the Maximum integration distance
Content_Manager posted this 23 October 2017

This parameter, RMAX, means those sources which their centroids are located further than RMAX will be ignored in the PSHA. For example, if RMAX=500 km, sources with distance between itself and site of interest greater than 500 km, will not be considered for the PSHA. The reason is because greater exceedance rates would be obtained for small values of acceleration, something directly related to the GMPE’s.
