My home straddles a fault, one side rising relative to the other. Scientificly, observations are interesting; in real life, it can be annoying.
Example: We have one of those old-fashioned genkan doors, two sliding parallel with the lock in the middle. Recently, the north door has become wedged in a position which prevents it unable to match with its southern counterpart, rendering the lock useless. It’s not a big deal in the short term - we live in a safe neighbourhood and have nothing worth stealing - but I suspected a mechanism and figured it out.
Southern Japan is particularly susceptible to a phenomenon known as “slow earthquake”, in which the earth shifts with no percptible feeling. Quite an interesting phenomenon, you can read more about it here: https://en.m.wikipedia.org/wiki/Slow_earthquake
Meanwhile, I’ve got to figure out what the hell to do about my door. - William
