Tsunami Survey for the February 21, 1996 Peruvian Earthquake

9634142叶这次行动是为了支持一个小侦察队从1996年2月21日的秘鲁地震和海啸中吸取教训，以收集和研究易腐的洪水数据。 1996年2月21日，秘鲁北方沿海地区海底发生大地震，引发海啸，海啸以3至5米的波浪席卷钦博特港，摧毁了鱼类加工厂和50多座房屋，在复活节岛（60厘米）和夏威夷（25厘米）的验潮仪记录了海啸。 迄今收集到的信息表明，这是一次“海啸地震”-这一术语源于1994年尼加拉瓜地震，指的是一次异常有效地产生海啸的地震。 彻底调查“海啸地震”及其影响是至关重要的减灾方面，并根据最近的理论发展断层破裂机制的价值。 勘察小组将收集海啸影响的基本信息，包括爬高、水流模式和速度、验潮记录、结构破坏、冲刷影响、沉积物输送、地面震动强度、对河口和附近湖泊的影响，以及这次地震及其相关海啸造成的任何次级影响。该小组将努力遵循1995年在科罗拉多埃斯蒂斯公园举行的海啸测量讲习班以及1995年在华盛顿星期五港举行的海啸模拟讲习班提出的调查方法和程序建议。 由于国际海啸研究人员目前正在对1996年2月17日发生在印度尼西亚伊里安查亚北方海岸沿着的另一次大海啸地震（Mw 8.2）进行侦察，因此这支秘鲁海啸侦察队将相对较小。 然而，该小组的调查结果将通过海啸公告板广泛公布，该公告板是由西雅图的海洋大气署太平洋海洋和环境实验室发起和维持的因特网邮件名单。 调查结束后，将立即通过海啸公告板发布一份简要报告，公布最后结果，并在华盛顿大学万维网海啸主页上公布。所有收集的数据将根据要求提供。 ***

9634142 Yeh This action is to support a small reconnaissance team to learn from the February 21, 1996 Peru earthquake and tsunami, in order to gather and study perishable inundation data. On February 21, 1996, a large earthquake struck under the sea off the northern coastal region of Peru, triggering a tsunami which swept into the port of Chimbote with 3 to 5 meter waves, destroying fish processing plants and more than 50 houses, and which was recorded by tide gages at Easter Island (60 cm) and Hawaii (25 cm). The information gathered to date point to it being a "tsunami earthquake" -- a term resulting from the 1994 Nicaragua earthquake to indicate an earthquake which is unusually efficient in producing tsunamis. A thorough investigation of "tsunami earthquakes" and their effects is critical in terms of hazard mitigation, and valuable in light of recent theoretical developments in fault rupture mechanisms. The reconnaissance team will gather essential tsunami-effect information including runup, flow patterns and velocities, tide-gage records, structural damage, scouring effects, sediment transport, intensity of ground shaking, the effect on estuaries and nearby lakes, and any secondary effects caused by this earthquake and its associated tsunami. The team will attempt to follow the recommendations for survey methodology and procedures established at the 1995 Tsunami Measurement Workshop in Estes Park, Colorado, as well as the 1995 Tsunami modelling Workshop in Friday Harbor, Washington. Because international tsunami researchers are currently involved in a reconnaissance of another large tsunamigenic earthquake (Mw 8.2) that occurred along the northern coast of Irian Jaya, Indonesia, on February 17, 1996, this Peru tsunami reconnaissance team will be relatively small. However, the findings of this team will be announced widely through the Tsunami Bulletin Board -- an Internet mailing list initiated and maintained by the NOAA Pacific Marine and Environmen tal Laboratory (PMEL) in Seattle. Immediately after the survey, a brief report will be disseminated via the Tsunami Bulletin Board, with the final results being published, and also posted on the University of Washington World Wide Web tsunami home page. All the gathered data will be available upon request. ***
