The expectations approach to earthquake hazards suggests that the long-run effects of a particular serious earthquake event may be very substantial however, these effects depend on prior expectations and the way in which expectations are updated as a result of the event. Request for hazard modeling contributions the usgs requests that the earthquake hazard community bring to our attention new earthquake source and ground motion data or models that could be included in the nshm updates. Discuss the view that the impact of earthquake hazards depends primarily on human factors earthquakes are an example of seismic activity created by plate boundaries they can be caused by the subduction of oceanic crust which is densest at 29 g/cm3 under continental crust which weighs 27g/m3 at destructive plate boundaries. 2018-10-9  the earthquake is felt very strongly, people are alarmed and lose balance these effects correspond to an intensity of viii or greater this level of intensity may be reached with earthquakes with a magnitude of around 54 or greater.
