... As an unexposed (blind) thrust fault propagates, folding
of the layers of rock is accompanied by earthquakes. The shape of these folds may record how far the fault tip has propagated relative to the amount of displacement of the blocks on either side of the fault. This information can tell us where in the ...

Northwestern scientists shed new light on neurodegenerative diseases
