Earthquake wins, hands down. What is so interesting about this picture and why I am posting it, is because it is evidence of a very unusual earthquake. Notice that while the tracks are bent into a pretzel, the rest of the land shows no evidence of disruption. Why is that?
Well, the site I found this on had many people offering different theories, but I believe that it was caused by a compression earthquake. A normal railroad track would have been broken up at several points, for the impact of the earthquake would have been distributed more evenly. In this case however, the earthquake, which probably happened somewhere up ahead or behind this picture, created high energy waves in the ground which traveled through the rails until a weak point in the track was found. This weak point then buckled. That’s my theory. What’s yours?
