RAPID: Haiti Post-Seismic Deformation: Tide/Tsunami Gauges on Leogane Coast

这一快速反应集中于震后地表变形、沿海海啸灾害和可能的应力调整，从而预测在未来十年左右的时间里，海地太子港地区将发生第二次里氏7.0级地震。PI和他的小组将监测海地Leogane地区的地震后形变，该地区在1月12日7级地震后，近地表目前存在2-4米的滑动赤字，使用两个1毫米精度的潮汐测量仪和这项工作的远程遥测。他们将测量洛根湾的潮汐调和和潮汐振幅，用于美国地质勘探局目前正在进行的珊瑚隆起和沉陷模拟。他们还将安装补充的海啸测量仪，以监测如果发生大余震或预期的未来主震时的下降和激增，并在最大隆起区域附近安装GPS单元，以监测形变场的垂直和水平分量。结果将通过网页和文章向公众公布。遥测数据的可用性是一个相当大的好处，下面的网页将被放大http://cires.colorado.edu/~bilham/Haiti/index.html以使这些数据可用。国际和平协会还将一份公共宣传海报翻译成克里奥尔语，并将其置于加勒比地区。

This RAPID response is focused on post-seismic surface-deformation, coastal tsunami hazards and probable stress adjustment leading to the forecast occurrence of a second Mw¡Ý7.0 earthquake in the Port au Prince region of Haiti in the next decade or so. The PI and his group will monitor post seismic deformation of the Leogane area of Haiti where a 2-4 m slip deficit currently exists in the near surface following the 12 January Mw=7 quake using two tide gauges with 1 mm precision and remote telemetry for this work. They will measure the tidal harmonics and seiche amplitudes of the Bay of Logane for use in coral uplift and subsidence modeling currently being undertaken by USGS. They will also install a supplemental tsunami gauge to monitor drawdown and surge should a large aftershock or an anticipated future mainshock, occur and install a GPS unit near the region of maximum uplift to monitor vertical and horizontal components of the deformation field. The results will be communicated by web pages and articles to the public as they become known. The availability of telemetered data is a considerable bonus and the following web page will be enlarged http://cires.colorado.edu/~bilham/Haiti/index.html to make this data available. The PI is also translating a public outreach poster into Creole and placed in a Caribbean context.
