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，或预测附近地震后它们的发生，或评估它们引发海啸的可能性，或能够警告沿海社区即将发生的危险。水下滑坡和滑坡对美国沿海经济活动构成持续威胁，包括有价值的海上建筑和港口设施。近十年来，一些规模最大、最致命的海啸（如巴布亚新几内亚、弗洛雷斯岛、尼加拉瓜）与近岸水下滑坡或滑坡产生的波浪有关。这些事件引发的海啸上升到海平面以上100英尺，远远超过了此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滑塌危害评估的跨学科方法，其目标是促进对破坏大小和位置的确定性或概率预测的发展。具体来说，它将支持(1)一个研讨会，以展示所有相关学科的最新技术，(2)评估现有的预测模型，(3)比较数据库和案例研究，(4)关注未来的研究活动，(5)为公共机构撰写建议，(6)讨论建立一个研究中心，进一步预测水下滑坡和滑坡，并将这些应用于开发涉及美国沿海水域的可靠海啸预警。

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.
