As part of the National Science Foundation (NSF) funded EarthScope project, the USArray Transportable Array (TA) in Alaska and western Canada deployed near 200 telemetered broadband seismic and infrasound stations. This systematic coverage of continental Alaska and northwest Canada has provided an unprecedented dataset for the seismological community. The primary scientific target of EarthScope has been an understanding of structure, dynamics, and evolution of the North American continent, along with observations of geohazards. This large‐scale scientific experiment also inspired another simultaneous effort, the Alaska Amphibious Community Seismic Experiment (AACSE), and is complemented by numerous seismic and nonseismic field efforts in...

阿拉斯加和加拿大EarthScope重点部分简介

作为美国国家科学基金会（NSF）资助的EarthScope项目的一部分，位于阿拉斯加和加拿大西部的USArray可移动阵列（TA）部署了近200个遥测宽带地震和次声台站。对阿拉斯加大陆和加拿大西北部的这种系统覆盖为地震界提供了前所未有的数据集。EarthScope的主要科学目标是对北美大陆的结构，动力学和演化以及对地质灾害的观察。这项大型科学实验还激发了另一项同时努力，即阿拉斯加两栖社区地震实验（AACSE），并且在...
