Tsunamis and tsunami warning: Recent progress and future prospects

Tsunamis are one of the most destructive disasters in the ocean. Large tsunamis are mostly generated by earthquakes, and they can propagate across the ocean without significantly losing energy. During the shoaling process in coastal areas, the wave amplitude increases dramatically, causing severe li...

Description
Summary:Tsunamis are one of the most destructive disasters in the ocean. Large tsunamis are mostly generated by earthquakes, and they can propagate across the ocean without significantly losing energy. During the shoaling process in coastal areas, the wave amplitude increases dramatically, causing severe life loss and property damage. There have been frequent tsunamis since the 21st century, drawing the attention of many countries on the study of tsunami mechanism and warning. Tsunami records also play an essential role in deriving earthquake rupture models in subduction zones. This paper reviews the recent progress and limitations of tsunami research, from the aspects of tsunami generation, propagation, inversion and warning. Potential tsunami warning strategies are discussed and future prospects on tsunami research are provided.
