Caribbean Tsunami Workshop

这一行动是为了支持将于2003年7月/8月在波多黎各圣胡安举办的一次讲习班，该讲习班的重点是加勒比地区的海啸威胁。加勒比的沿海人口正在迅速增长，虽然每个人都充分意识到飓风的威胁，并在很大程度上准备好应对飓风的危险，但该地区的大多数人并不知道海啸的危险。自1498年以来，已有27次经核实的海啸，另有9次“极有可能”。在过去的136年里，加勒比海东北部发生了三次破坏性的海啸，最后一次发生在1946年。在加勒比海地区，引发海啸的潜在来源包括地震、空中和海底山体滑坡以及水下火山爆发。现在公认的是，外星撞击在尤卡坦半岛形成了奇克苏鲁布陨石坑，并可能引发了一场巨大的海啸。引发海啸的一个潜在威胁来自加勒比海最活跃的火山--加勒比海东南部的Kick‘em Jenny海底火山。由加勒比开发银行资助的西印度群岛大学地震研究所正在监测其活动。此外，蒙特塞拉特Souffriere火山灾难性坍塌的可能性可能会引发威胁当地的巨大海啸。这次研讨会的主要目的是向国际海啸界通报加勒比海地区的海啸危险和海啸来源的多样性。同时，这次研讨会将为海啸模型界提供动力，以应对这一多重区域海啸威胁。还希望讲习班将使该区域的地方政府更多地认识到海啸的危险，并参与减轻这一威胁的规划。

This action is to support a workshop, to be held in San Juan, Puerto Rico in July/August 2003, to focus on the tsunami threat in the Caribbean region. The coastal population in the Caribbean is growing rapidly, and while everyone is fully aware of the hurricane threat and is, to a great extent, prepared to deal with the hurricane hazard, most people living in the region are not aware of the tsunami hazard.Since 1498, there have been twenty-seven verified tsunamis and an additional nine as "very likely". In the past 136 years there have been three destructive tsunamis in the northeastern Caribbean, the last one occurring in 1946. In the Caribbean Sea region the potential sources for tsunami generation include earthquakes, sub-aerial and submarine landslides, and underwater volcanic explosions. An extra-terrestrial impact is now accepted as having formed the Chicxulub crater in the Yucatan Peninsula, and presumably generated an enormous tsunami. One potential threat for generating tsunamis comes from the most active volcano in the Caribbean, the Kick'em Jenny submarine volcano at the southeastern Caribbean. The University of the West Indies Seismic Research Unit (UWI/SRU), funded by the Caribbean Development Bank, is monitoring its activities. Also, the potential of a catastrophic collapse of the Souffriere volcano in Montserrat could generate a huge tsunami threatening the local area.The main objective of this workshop is to inform the international tsunami community of the tsunami hazard in the Caribbean Sea region and the diversity of tsunami generating sources. At the same time, this workshop will provide a motivation for the tsunami modeling community to address this multiple regional tsunami threat. It is also hoped that the workshop will inform and motivate local governments in the region to become more aware of the tsunami hazard, and involved in planning to mitigate this threat.
