| 摘 要： | Quantitative analysis on seismicity showed that there are several seismic dense zones in Bohai Sea. These seismic dense zones of modern small earthquakes behave prominent NE orientation, although a seismic dense zone with NW direction exists actually. Taking 39°N as a boundary, seismicity in the south is different from that in north of Bohai Sea. Almost all strong earthquakes and seismic dense zones are concentrated in the southern part. Based on archives and seismic dense characteristics, we amended the epicenter of strong earthquakes in 1548 and discussed about magnitude of the earthquake in 1888. Possibility of the event in 173 as a tsunami was discussed. The event in 1597 was doubted as a strong earthquake in Bohai Sea.

| Abstract: | Quantitative analysis on seismicity showed that there are several seismic dense zones in Bohai Sea. These seismic dense zones
of modern small earthquakes behave prominent NE orientation, although a seismic dense zone with NW direction exists actually.
Taking 39°N as a boundary, seismicity in the south is different from that in north of Bohai Sea. Almost all strong earthquakes
and seismic dense zones are concentrated in the southern part. Based on archives and seismic dense characteristics, we amended
the epicenter of strong earthquakes in 1548 and discussed about magnitude of the earthquake in 1888. Possibility of the event
in 173 as a tsunami was discussed. The event in 1597 was doubted as a strong earthquake in Bohai Sea.
