U.S.-Italy Cooperative Research: Empirical Studies of Sediment Amplification in Rome and New York

该奖项将支持哥伦比亚大学拉蒙特-多尔蒂地质观测站（L-DGO）的Leonardo Seeber和Susan Hough与意大利罗马国家地球物理研究所的Renato Funiciello和Antonio Rovelli合作进行的一项研究。这次地震研究合作的主要目的是利用环境噪声的测量来研究充满沉积物的山谷的共振模式。对于高噪声的城市环境，环境噪声法在经济、快速地识别主要共振频率方面具有很大的前景。对共振模式的认识和兴趣急剧上升，部分原因是最近的大地震。由于泥沙共振，其中许多对人和财产造成了特别严重的破坏。美国和意大利的联合合作将提供一个机会，将两国的仪器结合起来，并在了解沉积物放大及其与地震危险的关系方面交流想法和经验。

This award will support Leonardo Seeber and Susan Hough from the Lamont-Doherty Geological Observatory (L-DGO) of Columbia University in a research collaboration with Renato Funiciello and Antonio Rovelli of the National Institute of Geophysics in Rome, Italy. The principal objective of this earthquake research collaboration is to use measurements of ambient noise to study resonant modes of sediment-filled valleys. For high-noise urban environments located on sediment-filled valleys, the ambient noise method shows promise in the economical and quick identification of predominant resonance frequencies. Awareness of and interest in resonant modes has risen dramatically partly because of recent large earthquakes. Many of these were especially devastating to people and property due to sediment resonances. This joint U.S.-Italy collaboration will provide an opportunity to combine instrumentation from the two countries as well as exchange ideas and experiences in understanding sediment amplification and its relevance to seismic hazard.
