A Thai friend told me that Bangkok sinks 1/2″ each month, yet grows 1″ each month. This is part joke and part fact- Bangkok largely sits on water with “klongs” or canals everywhere; it is said that Bangkok is sinking and/or the water level is rising.
Bangkok is also constantly rising- there are construction cranes dotting the skyline. I found a picture from just over a year ago and one from a week ago that show a building under construction and the difference….around 36 floors added in 52 weeks.
Sinking and Rising.
