Matt Black is a photographer who searches regions of the world where natural disasters occur most frequently. He captured this area in Mexico called Mixteca, known as the most erroded piece of land, topographically, on earth. He writes and says: "Southern Mexico's Mixteca region is one of the most heavily eroded landscapes on earth: up to five meters of topsoil have been lost. In the town of Santiago Mitlatongo, soil loss triggered a geological phenomenon called "slumping." Like a slow-motion landslide, the town is sliding downhill at the rate of one meter per day, destroying homes and livelihoods as houses and farmland slip into the valley below."
