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.

After Silva posted his video on YouTube, it was quickly copied and shared on various social media platforms.
