 Across the world, thousands of precariously balanced rocks—giant boulders seemingly poised to fall at any moment—have captured the attention of both hikers and scientists. These gravity-defying rocks, once considered mere geological curiosities, are now providing invaluable insights into earthquake activity and seismic risk, long before modern seismometers could detect the trembling of the Earth. Nature’s Witnesses: Rocks That Defy Gravity Precariously balanced rocks (PBRs), scattered across the globe from the UK’s Brimham Rocks to India’s Krishna’s Butterball, are often striking for their oddity. These boulders seem as though they’ve been placed by human hands, teetering on narrow bases or perching on high points, but in reality, their delicate balance is the result of natural forces over long periods of time. Whether carried by glaciers or eroded to their current precarious positions, these boulders offer a unique geological perspective. In some cases, glaciers have dropped mass...
