After the big quake (and tsunami) off Sumatra, I noticed a 5.5 ft (1.8m) long crack in the ceiling over my bed. And today, I just found a 6-7 feet (2-2.5m) long crack in the kitchen ceiling! It wasn't there during the big quake, so it must have been the result of the last (smaller) quake off Sumatra. I will try to get some pictures tomorrow. But man, this is rather troubling... My condominium only has 9 floors and my unit is only on the 3rd floor. I can only imagine the damage on the upper levels.
