Calculations

This application currently performs the RTGM calculation for a single intensity measure (IM) hazard curve at a time. For bulk calculation of RTGMs for a larger number of IM hazard curves, please refer to https://earthquake.usgs.gov/ws/nshmp/designmaps/rtgm/ or https://code.usgs.gov/ghsc/erp/erp-rtgm-calculator
