Damn Nature U Scary of the Day: Train tracks near Rolleston, New Zealand, shortly following the 2010 Canterbury earthquake.
From Dave Petley, Professor of Hazard and Risk in the Department of Geography at Durham University:
My initial hypothesis here (I am no expert on railway track deformation) in order to stimulate discussion is that the buckling may be the result of compressional deformation across a broad zone. The compression on the very strong railway line was accommodated when a weak point was found, leading to a comparatively rapid deformation to form the main buckle on the left. This then concentrated stress on both sides of the buckle, allowing the other (right side) bends to form.
