As Mexico reels from the destruction of a recent earthquake, a strange phenomenon has surfaced on its streets.
Video shows a patch of asphalt rising and buckling as if a large animal were taking big, heaving breaths somewhere beneath Mexico City. The phenomenon was spotted by resident Rigoberto Lechuga Silva on Sept. 19, just as the earthquake tremors rippled through his neighborhood.
Silva rushed into the street with the many others trying to evade swaying buildings. He noticed a lamp post wobbling and took out his phone to record the movement when he spotted the concrete rising and falling.
After Silva posted his video on YouTube, it was quickly copied and shared on various social media platforms.
