Earthquake intensity hazard 475 year event
WebThe maps were compiled based on the PSHA approach, with the seismic hazard defined by PGA values for the 95-year return period earthquake (“damage limitation” requirement), and the 475-year return period earthquake (“no-collapse” requirement), see Fig. 2. Both maps show PGA values for the ground type A, defined by the code as the ... WebThe levels of danger refer to the intensity of an earthquake in a specific warning area. The intensity is a measure of the effects of an earthquake. Using a 12-point scale , it describes the consequences of an earthquake for people and buildings in a particular place. An earthquake has one value for magnitude (energy released) and usually ...
