Grass Valley, California. Hall County, Georgia. Fraser, Michigan. Philadelphia, Pennsylvania. Bethlehem, Pennsylvania. What do these locations have in common? Sinkholes. Each of the sinkholes occurred within the last three weeks. These sinkholes collapsed roads, sidewalks, and houses, and swallowed vehicles, causing millions of dollars in damages, and many will take weeks, if not months to repair.
Over 80 percent of the land subsidence across the nation can be contributed to human interference – through development and underground water exploitation. Land subsidence has directly impacted 45 states and over 17,000 square miles. A size that is nearly equivalent to New Hampshire and Vermont combined.
