The steep paths are dangerous, the sulfur gases are poisonous, and occasional gas releases or phreatic eruptions have killed many miners. The eruption jostled its crater lake, which resulted in the lake overflowing, and creating a mudslide which destroyed many villages in the vicinity. Miners make one or two trips per day carrying up to 200 pounds of sulfur. Thousands of years of weathering have converted the pyroclastic deposits into rich, fertile soils which now support coffee plantations. The eruption displaced the crater lake and resulted in inundation of several villages along the drainage route.
