[SCG58-06] High precision prediction of dynamic instabilities

Keywords:buckling, earthquake, prediction, Critical slowing down

Prediction of dynamic instabilities in collapse of buildings, landslides and earthquakes is very important for preventing damages. Here we report our experiments on multiple degree-of-freedom snap-through buckling where we can predict the onset of dynamic instabilities with high precision. We also apply this idea to laboratory earthquake experiments and discuss how it works.
