Abstract：In the seventies and eighties of last century, Guangdong Earthquake Agency has sent earthquake workers twice to Chaoshan area to investigate the Nanao Earthquake in 1918. They widely collected the disaster situation of villages in the earthquake disaster area, which provide a reliable basis for the determination of distribution range of the seismic intensity influence field and the epicenter position. Based on above, it can be inferred that the Nanpeng Islands conjugate fault activity construction in the high intensity area is the seismic structure of the Nanao earthquake.Due to the seismogenic tectonic mechanism the Nanpeng Isliand,there existed anomaly in the coastline in Chaoshan and southern Fujian region with the tide retreating and then rising again. The Nanao earthquake is the only earthquake with a tsunami in 20th century near South China Sea offshore.
