It's not discussed in the article but I'm very curious about the brightest spot in the SF Bay Area in the survey image. It's not Millenium Tower (which I work next to so that's pretty interesting too). It's actually the land just west of Oakland airport, the part of Alameda built up in the 80s called Bay Farm. As I understand it the area was marsh up until then -- that and a garbage dump that has since been covered.

Does anyone know if the land there really is sinking so fast? It's not on a fault so I'm fairly sure it's not moving much laterally.
