Tsunami risk research on coastal areas in Fujian Province, China

Abstract

Tsunamis can cause significant loss of life, major property and environmental damage in coastal cities. The great destructive tsunamis have heightened the awareness of the study of potential risk. We adopt multiscale scenarios to test the tsunami risk, according to the analysis of historical seismic events and geologic structure. Local, regional and transoceanic tsunami sources might pose a significant potential threat to Fujian Province, which faces the open sea. The tsunami wave height distributions along coastline for hypothetical extreme rupture events are simulated. The tsunami risk of different level for coastal area was analyzed. The results are useful for understanding the potential risk of Fujian province. Furthermore, prevention measures for tsunami need to be prepared, and emergency plans must be made previously in coastal Provinces under the potential tsunami threat.
