9601489 Street This grant, made through the Academic Research Infrastructure (ARI) Program, provides $110,356 as partial support of the costs of acquiring instrumentation for high-resolution shear-wave investigations within the New Madrid Seismic Zone (NMSZ). Specific equipment will include a Minivib seismic source to produce both compressional and shear waves at sufficient force and at frequencies enabling penetration to 1.5-2 km depths, a 24-bit, 48 channel seismograph, geophones and cables, and an upgrade to their current seismic processing software that will license them to process Vibroseis type data. This high frequency source and multi-channel seismograph will allow high- resolution imaging of the semi-consolidated soils that lie over Paleozoic strata in the Upper Mississippi Embayment. Characterization of the thickness of these layers and shear wave velocities within these layers will provide useful data for seismic hazard mitigation and engineering purposes. ***

邮编：9601489 这项赠款是通过学术研究基础设施（ARI）计划提供的，提供了110，356美元，作为购买新马德里地震带（NMSZ）内高分辨率剪切波调查仪器的部分支持。 具体设备将包括一个Minivib地震源，以产生足够的力量和频率的压缩波和剪切波，能够穿透1.5-2公里的深度，一个24位48通道地震仪，地震检波器和电缆，以及升级其现有的地震处理软件，使其能够处理可控震源类型的数据。 这种高频震源和多道地震仪将允许对位于上密西西比湾古生代地层上的半固结土壤进行高分辨率成像。 这些层的厚度和剪切波速度在这些层的特性将提供有用的数据，地震灾害减轻和工程目的。 ***
