Episode 512 - Analyzing aftershocks and predicting earthquakes

Forecasting an earthquake is serious business, but it's not like the weather. Why are earthquakes so hard to predict? Knowing when an earthquake will occur is hard enough, but what about predicting aftershocks? Aftershocks can create huge stress and compound damage after a quake so what can be done to predict them? Building huge scale models out of granite can help researchers better understand aftershocks. Sliding slabs of granite, plastic blocks and quartz dust help researchers understand aftershocks. When an earthquake combines with another disaster, the compound effect is devastating. How good are modern risk assessment tools at managing compound disasters?  Sara Beth L.
