Have you ever experienced an earthquake? This probably isn’t something you think about often, especially if you live in southern Indiana, where earthquakes large enough to be felt (or cause any damage) are quite rare.

A large portion of the damage was caused by landslides that were triggered by shaking from the earthquake. An example of this devastation can be seen in the image above, where a landslide completely destroyed the Great Aso Bridge in Minamiaso, Japan. (more…)
