RECENT SINKING IN THE DONGZHAI HARBOUR AREA, NORTHERN QIONGZHOU

An Earthquake of the magnitude of 7.5 on the Richter scale in Qiongzhou in 1605 led to the sinking of quite large an area in the Dongzhai Harbour area. Through extensive investigations and researches on tombs, houses and steles etc. the author verified this area was constantly in the process of sinking at the rate of >lcm/yr. after the event, which might be a continuity of the vertical movment caused by over-and under-crust movment since the cenozoic era.
