Look at the first and 3rd pics after the video. You can clearly see the crater. You can also see the piers from below the pool deck sticking up from below, see the number 42 written on the white pier designating a parking spot. That belongs under the deck. The pool area collapsed and took down the rest. Look at the cars, they have fell 4 feet, see parking spot #72. The parking deck belongs above the white part of the pier. The brown part of pier should be above ground.
Indeed. Great eye! Informative pics of part of the pool deck collapse.
