WebAug 1, 2014 · Class 2 earthquakes are earthquakes that have a CR JB distance less than a selected limit and within a time window appropriate for aftershocks. All other earthquakes are classified as Class 1. For maximum CR JB of 0 km and 40 km, 11% and 36% of the earthquakes in the NGA-West2 database are Class 2 events, respectively. WebThe Arias intensity based factor of safety FI hb against liquefaction occurrence is defined as the ratio of the Arias intensity required to cause liquefaction to the Arias intensity imparted by the earthquake. This Arias intensity definition of factor of safety is analogous to that defined by Seed and his colleagues based on cyclic stress (F CSR).
