摘要

There have been 12 possible locations of the earthquakes occurring in the South Yellow Sea since 1505. In this paper, the location of the earthquake that occurred in 1505 has been determined by the collection of more historical data of the influenced field, referring the isoseismal data of earthquakes with the epicentral intensity IX and combining geophysical field data with tectonic condition due to its great influence on seismic safety assessment of some significant engineering.
