May 16, 2023 · 4. Use water sparingly if you live in an area with frequent droughts. Underground aquifers often help to prevent sinkholes because the water fills in cracks and holes that would normally cause settling. If the water isn’t present, the soil and rocks have more space to move and cause sinkholes. Landslides kill at least a thousand people each year but because they are often triggered by earthquakes or heavy rains, the danger remains poorly understood.
