The tsunami source of the Manila seismic tsunami was designed and computed to analyze the risk of tsunami which will happen in the Guangdong coast. According to the results, the maximum quantity of water increasing and the time of the tsunami arriving at the Guangdong seacoast were calculated. The coupling simulation between astronomical tide and tsunamis has significant meaning for evaluating the risk and early-warning of tsunamis in the Guangdong coastal area.展开更多

These seismic dense zones of modem 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.展开更多

Due to the high probability of earthquakes throughout the country and the potential for tsunami inundation along the coasts and offshore, comprehensive studies on theinteraction of these natural phenomena arc necessary, hi this study, the most conservative scenarios are determined for possible earthquakes within the Khark zone (Persian Gulf) ba.sed on experimental relations between tile fault length, magnitude and displacement, which are paralneters for deter- mining tsunamigenic sources. Subsequently, the maximum height of tstmami waves are calculated based on the specitieations of the seismic source and its distance from the shore as well as the coastal slope. A zoning map of tsunami hazard is finally presented.展开更多
