Californians have seen a concerning photo: a person standing next to a telephone pole with signs labeled with years, showing the ground level for each year.
The signs on the pole read: "1962" at the top, "1970" several feet lower, "2015", "2019", "2021", and "2025" at the bottom.
Each sign represents the ground level for that year, illustrating how much the ground has sunk due to subsidence.
