The southeast coastal seismic belt mainly includes Fujian and Guangdong provinces and a small part of Jiangxi and Guangxi. The seismic belt is controlled by the Neocathaysian ne-trending active fault, which is roughly parallel to the coastline. In addition, some NW-trending active faults also played a certain role in the formation of seismogenic conditions. This group of NE-trending active faults are Changle-Zhaoan fault zone, Zhenghe-Haifeng fault zone and Shaowu-Heyuan fault zone in turn from east to west. There have been many destructive earthquakes along the fault zone, such as Changle area.

Zhao' an fault zone, there was 1604 Quanzhou overseas M 8 earthquake and a series of strong earthquakes near South Australia; There have been earthquakes with magnitude of Huichang 6.0 (1806), Heyuan 6. 1 (1962) and Xunwu 5.8 (1987) along the Shaowu-Heyuan fault zone, and destructive earthquakes have also occurred along the Zhenghe-Haifeng fault zone, but the overall intensity is low. Generally speaking, it happens once every 20 years on average. Thank you, elite education teacher.
