Document Summary
River born sediments close to water table. River - transports sand and mud which when saturated with water is susceptible to liquification. So when buildings are built on top of those types things sink in, and movement will be amplified. Understanding of how earthquakes triggered, sediment type understand - forecasts + predictions become closer together. Forecast: use geologic deposits (history) to build an idea of frequency of estimates, magnitude of event sometimes, determine probability of event happening. Before and after, predict based on current conditions of strain etc: seismic gaps - historical graphs help forecast when certain events may occur. Convince the funding of pipelines and other constructions to be safer in case of disasters. Land level change: uplift or subsidence, use gps to track changes in land height - (cid:271)ut do(cid:374)"t k(cid:374)o(cid:449) (cid:449)he(cid:374) ho(cid:449) (cid:373)u(cid:272)h is (cid:396)aised is bad. Seismic gaps: based on prior evidence, see if you are to expect something.
