海啸是影响沿海地区的最具破坏性和最不可预测的自然灾害之一。就在三年前，即2004年12月，印度洋海啸造成225 000多人死亡。然而，像许多极端事件一样，破坏性的海啸很少发生，书面记录的时间太短，无法量化海啸的危害和风险。保存在地质记录中的海啸沉积物被用来延长海啸发生的记录，但不是过去事件的规模。为了进一步量化海啸的危害，我们提出了以下问题：古代沉积物是否也能为未来海啸的预期水深和速度提供指导？
Tsunamis rank among the most devastating and unpredictable natural hazards to affect coastal areas. Just 3 years ago, in December 2004, the Indian Ocean tsunami caused more than 225,000 deaths. Like many extreme events, however, destructive tsunamis strike rarely enough that written records span too little time to quantify tsunami hazard and risk. Tsunami deposits preserved in the geologic record have been used to extend the record of tsunami occurrence but not the magnitude of past events. To quantify tsunami hazard further, we asked the following question: Can ancient deposits also provide guidance on the expectable water depths and speeds for future tsunamis?
