Caribbean Tsunami Workshop

这项行动是为了支持将于2003年7月/ 8月在波多黎各圣胡安举行的一个讲习班，重点讨论加勒比地区的海啸威胁。加勒比沿海地区的人口正在迅速增长，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应付飓风的危险，但居住在该地区的大多数人却不知道海啸的危险。自1498年以来，已经发生了27次经证实的海啸，另有9次“很可能”发生。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，最近一次发生在1946年。在加勒比海地区，产生海啸的潜在来源包括地震、空中和海底滑坡以及水下火山爆发。现在，人们认为是一次地外撞击形成了尤卡坦半岛的希克苏鲁伯陨石坑，并可能引发了巨大的海啸。引发海啸的一个潜在威胁来自加勒比海最活跃的火山，位于加勒比海东南部的基杰姆珍妮海底火山。由加勒比开发银行资助的西印度群岛大学地震研究单位（UWI/SRU）正在监测其活动。此外，蒙特塞拉特的苏弗里埃火山可能发生灾难性的崩塌，可能会引发巨大的海啸，威胁到当地地区。这次讲习班的主要目标是向国际海啸界通报加勒比海地区的海啸灾害和海啸产生源的多样性。与此同时，本次研讨会将为海啸建模界提供动力，以应对这一多区域海啸威胁。人们还希望，该研讨会将告知并激励该地区的地方政府提高对海啸危害的认识，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.
