The cities include not just those on the coasts, where sea level rise is a concern, but many in the interior.

      Its population is too small to make it into this study, but it was mentioned in the press release from Colombia alongside Venice and Jakarta as rapidly subsiding coastal metropolises that have drawn media attention.

    The nation’s fastest-sinking city is Houston, with more than 40% of its area dropping more than 5 millimeters (about 1/5 inch) per year, and 12% sinking at twice that rate.

    Understanding subsidence in the Houston-Galveston region

    Since 1836, groundwater withdrawals have caused about 3,200 square miles of the Houston-Galveston area to subside (or sink) more than a foot, with some areas subsiding as much as 12 to 13 feet.

    Noob-tier numbers, Texas. Here’s a photo from 1977 in California showing land subsidence on a telephone pole from 1925 to 1977.

      My brain isn’t working? The pole was installed and ground receded 9 meters over the years? How far into the ground was the pole driven in the beginning?

        The pole is just an ordinary pole. In 1977, after measuring land subsidence over time, they put the signs up on it to illustrate how far the land had sunk. They could have put the signs on anything tall enough to provide enough space.

        No, here’s the caption.

        Figure 2. Approximate location of maximum subsidence in the United States identified by research efforts of Dr. Joseph F. Poland (pictured). Signs on pole show approximate altitude of land surface in 1925, 1955, and 1977. The site is in the San Joaquin Valley southwest of Mendota, California.

    Lol at first I thought they were talking about population shrinking.

    Not my problem. I also like how the chart has a legend showing what colors they would use if the city was rising. “Albuquerque is getting taller!”
