This action is to support a field survey of the effects of the tsunami generated by the Southern Peru earthquake of 23 June 2001. The survey involves a 9-person team for a total of nine days in the area impacted by the tsunami. The objective is to gather a coherent database of runup and inundation measurements, to be used later in computer modeling efforts aimed at unraveling the exact mechanism of generation of this tsunami.Preliminary reports indicate that a tsunami was generated and recorded as far away as Japan. Locally, reports indicate a series of five waves (with periods on the order of half-an-hour) destroying built-up structures and inundating as far as 1.5 to 2 km inland in the area of Camana.This survey represents a continuation of the work carried out for the past decade in the aftermath of significant tsunamis worldwide, in order to gather coherent, quantitative sets of modern data which can then become the basis for modeling the source of the tsunami through state-of-the-art computational techniques. For past tsunamis, the comparison between simulations for a variety of sources of the tsunami and the surveyed dataset has provided fundamental and occasionally unexpected insight into the dynamics of the ocean floor during, or immediately following, an earthquake in the marine environment.The information from this survey, as with previous surveys, will be distributed worldwide via the tsunami Internet bulletin board.

这一行动是为了支持对2001年6月23日秘鲁南部地震引发的海啸的影响进行实地调查。这次调查包括一个由9人组成的小组，他们在受海啸影响的地区进行了为期9天的调查。其目标是收集累积和淹没测量数据的连贯数据库，以便稍后在计算机建模工作中使用，旨在揭示这次海啸产生的确切机制。初步报告显示，远至日本都有海啸的记录。当地的报告显示，连续五波（周期约为半小时）摧毁了建筑结构，淹没了卡马纳地区1.5至2公里的内陆地区。这项调查是过去十年在全球重大海啸之后开展的工作的延续，目的是收集连贯、定量的现代数据集，然后通过最先进的计算技术成为建立海啸来源模型的基础。对于过去的海啸，对各种海啸源的模拟与调查数据集之间的比较，为海洋环境中地震期间或地震后的海底动力学提供了基本的、偶尔意想不到的见解。与以前的调查一样，这次调查的信息将通过海啸互联网公告板向全世界发布。
