WebOur nation-wide seismic hazard assessment defines the level of earthquake ground shaking across Australia that has a specified likelihood of being exceeded across a given time period. This information is used by building standards and decision makers to develop mitigation strategies so that communities can be more resilient to earthquake events. Web10 nov. 2016 · The cause of earthquakes is the accumulation of stress that builds up within Earth’s lithosphere: in a region that’s virtually impossible for us to see, and over time scales that can be tricky for us to monitor.
