A large earthquake, called the"Bunsei Kyoto earthquake,"occurred at about 3 : 00 P.M.-5 : 00 P.M. 2nd day of 7th month, Bunsei 13th (Gregorian calendar: 19 August, 1830) in Kyoto, Kinki district, Japan, causing enormous damage, especially in the central part of Kyoto city. Large structures of representative architecture in Kyoto city at the time such as the Nijo Castle, Imperial Palace, and major temples, as well as the walls (e.g., stone walls or tamped earthen walls) surrounding them were heavily damaged. Further, there were collapses of a number of Machiya, traditional Japanese residential architectural style incorporating workplaces of merchants and craftsmen, which caused many casualties. About 60% of the area of Kyoto city was occupied by such buildings housing merchants and craftsmen in those days. One major contributing factor of the collapses of Machiya is thought to be the rapid diffusion of pantile roofs in the 19th century.
