Crustal Thickness Variations in the Central Midcontinent, USA, and Their Tectonic Implications: New Constraints Obtained Using the H‐κ‐c Method

Autor: Hongyu Xiao, Michael DeLucia, Xiaodong Song, Jiangtao Li, Stephen Marshak

Publikováno v: Geophysical Research Letters, Vol 49, Iss 17, Pp n/a-n/a (2022)

Abstract The central midcontinent of the USA's cratonic platform is a region of low elevation and relief underlain by tectonic basins, domes, faults, and monoclines. To investigate potential correlations among shallow crustal structure and crustal th

Resolving Northern Alaska Earthquake Sequences Using the Transportable Array and Probabilistic Location Methods

Autor: Kasey Aderhold, Natalia A. Ruppert, Ezgi Karasözen, Steven J. Gibbons, Ian Dickson

Between 2014 and 2017, almost 200 new seismic stations were installed in Alaska and northwestern Canada as part of the EarthScope USArray Transportable Array. These stations currently provide an unprecedented capability for the detection and location

The Mackenzie Mountains EarthScope Project: Studying Active Deformation in the Northern North American Cordillera from Margin to Craton

Autor: Richard C. Aster, J. F. Cubley, Derek L. Schutt, Jeffrey T. Freymueller, M. G. Baker, David C. Heath

Publikováno v: Seismological Research Letters. 91:521-532

The Mackenzie Mountains EarthScope Project—a collaboration between Colorado State University, the University of Alaska, Michigan State University, and Yukon College—deployed a roughly linear, 40-station broadband seismographic network. This netwo

Obtaining free USArray data by multi-dimensional seismic reconstruction

Autor: Yangkang Chen, Yunfeng Chen, Min Bai

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-13 (2019)
Nature Communications

USArray, a pioneering project for the dense acquisition of earthquake data, provides a semi-uniform sampling of the seismic wavefield beneath its footprint and greatly advances the understanding of the structure and dynamics of Earth. Despite continu

P Wave Teleseismic Traveltime Tomography of the North American Midcontinent

Autor: Andrew Frederiksen, Suzan van der Lee, Douglas A. Wiens, Seth Stein, Fiona Darbyshire, M. E. Wysession, Emily Wolin, T. A. Bollmann, Justin Revenaugh, Donna M. Jurdy

Publikováno v: Journal of Geophysical Research: Solid Earth. 124:1725-1742

The remains of the 1.1‐Ga Midcontinent Rift (MCR) lie in the middle of the tectonically stable portion of North America. Previous and ongoing studies have imaged strong heterogeneity associated with the MCR in the crust but have not imaged such wit

Heterogeneous distribution of water in the mantle transition zone inferred from wavefield imaging

Autor: Mingming Li, Gary L. Pavlis, Yinzhi Wang

Publikováno v: Earth and Planetary Science Letters. 505:42-50

The amount of water in the Earth's deep mantle is critical for the evolution of the Earth. Mineral physics studies revealed that the mantle transition zone can store several times the volume of water in an ocean. However, the actual water distributio

Deep electrical structure of Cascadia derived from 3D anisotropic inversion of USArray long-period magnetotelluric data

Autor: C. Yin, C. Qiu, Z. Rong, Y. Liu, X. Cao

Publikováno v: 82nd EAGE Annual Conference & Exhibition.

Summary For a long time,geologists believed that the frequent occurrence of earthquakes in the west coast of the United States is closely related to the existence of a north-south Cascadia subduction zone in the deep part of the region. the National
