Workshop on the Prediction of Underwater Landslide & Slump Occurrence And Tsunami Hazards Off Of Souterhn California

科学家和工程师目前无法评估水下滑坡和滑坡的风险，也无法预测附近地震后它们的发生情况，也无法评估它们引发海啸的潜力，也无法警告沿海社区迫在眉睫的危险。水下滑坡和滑坡对美国沿海经济活动构成持续威胁，包括宝贵的近海建筑和港口设施。本十年一些最大和最致命的海啸(如巴布亚新几内亚、弗洛雷斯岛、尼加拉瓜)涉及近岸水下山体滑坡或塌方产生的波浪。这些事件引发的海啸上升到了海拔100英尺的高度，远远超过了之前对此类中等地震的最大海啸幅度的预测。这一行动是为了支持水下滑坡和坍塌风险评估的跨学科方法，目标是促进对故障大小和位置的确定性或概率预测的发展。具体地说，它将支持(1)研讨会，展示所有相关学科的最新技术，(2)评估现有预测模型，(3)比较数据库和案例研究，(4)重点关注未来的研究活动，(5)为公共机构撰写建议，以及(6)讨论建立一个研究中心，以进一步预测水下滑坡和塌方，并将这些研究中心应用于开发涉及美国沿海水域的可靠海啸警报。

Scientists and engineers are currently unable to assess underwater landslide and slump risk, or to predict their occurrence following a nearby earthquake, or to evaluate their tsunamigenic potential, or be able to warn coastal communities of imminent danger.Underwater landslides and slumps pose a continuous threat to US coastal economic activity, including valuable offshore structures and port facilities. Some of the largest and most deadly tsunamis this decade (e.g. Papua New Guinea, Flores Island, Nicaragua) involved wave generation by nearshore underwater landslides or slumps. These events generated tsunami runup reaching 100 feet above sea level, far surpassing most previous predictions of maximum tsunami amplitude for such moderate earthquakes.This action is to support an interdisciplinary approach to underwater landslide and slump hazard assessment, with the goal of contributing to the development of deterministic or probabilistic predictions of failure size and location. Specifically, it is to support (1) a workshop to present the state-of-the-art in all pertinent disciplines, (2) evaluate existing predictive models, (3) compare databases and case studies, (4) focus future research activities, (5) write recommendations for public agencies, and (6) discuss the creation of a research center to further predictions of underwater landslide and slump, and to apply these to the development of reliable tsunami warnings involving US coastal waters.
