A seismic model for crustal structure in North China Craton

Earth and Planetary Physics, 2017
We present a digital crustal model in North China Craton (NCC). The construction of crustal model is based on digitization of original seismic sounding profiles, and new results of three-dimensional structure images of receiver functions.

The Bauhaus as Education Model: Enduring Design and Powerful Knowledge

International Journal of Art &Design Education, EarlyView.
Abstract The influence of the Bauhaus art, design, and architecture school is still relevant a century after it was closed down. Although its theory of learning is somewhat elusive there is significant agreement that the school continues to inspire domestic and commercial design, as well as stimulating interdisciplinary learning in institutions across ...

Timing of Metamorphism and Deformation in the Neoarchean Quetico Metasedimentary Belt, Superior Craton, Constrained by Garnet Trace‐Element Mapping and Lu–Hf Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The Quetico subprovince of the Superior Province is among the largest metasedimentary belts globally and provides evidence of tectonic processes at play during the final stages of Archean cratonization. Although previous studies have shown that deformation and metamorphism of the 2.7‐Ga turbiditic protolith resulted in regional subvertical ...

Determining the Moho topography using an improved inversion algorithm: a case study from the South China Sea

Frontiers in Earth Science
The Parker-Oldenburg method, as a classical frequency-domain algorithm, has been widely used in Moho topographic inversion. The method has two indispensable hyperparameters, which are the Moho density contrast and the average Moho depth.

Moho Beneath Tibet Based on a Joint Analysis of Gravity and Seismic Data

Geochemistry, Geophysics, Geosystems, 2020
We use the improved Parker‐Oldenburg's formulas that include a reference depth into the exponential term and employ the Gauss‐fast Fourier transform method to determine Moho depth beneath the Tibetan Plateau.

The 2025 Puerto Rico and Virgin Islands U.S. National Seismic Hazard Model Update: Ground Motion Model Selection and Comparison

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We evaluate, select, and describe the ground‐motion models (GMMs) used in the 2025 update of the U.S. National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). We identify the most appropriate models that align with GMM selection criteria for use in the PRVI region to improve the accuracy of seismic hazard assessments ...

首都圈及其邻区的电性莫霍面探测

Dizhen xuebao
为了解首都圈地区电性莫霍面（eMoho）的分布情况，使用该地区电磁台网部分台站的长周期大地电磁数据，反演得到了首都圈地区的深部电性结构，该结果与前人使用地震、电磁、重力等资料得到的研究区地下结构具有较好的一致性，同时表明首都圈地区的地震学莫霍面附近也存在着电阻率变化特征。在此基础上，对反演所得的电阻率曲线求取一阶导数，以此来刻画测点下方电性莫霍面的深度位置，继而建立三类地层模型验证了该方法的可行性，并对实测资料反演结果求取一阶导数，结果凸显了电性莫霍面的分布，所得电性莫霍面与地震 ...

Crustal Magma Storage and Plumbing System Beneath the Tianchi and Wangtian'e Volcanoes, Changbaishan Intraplate Volcanic Field, China and North Korea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The Changbaishan volcanic field, which includes the Tianchi and Wangtian'e volcanoes in China and the Namphothe volcano in North Korea, is one of the most complex and hazardous volcanic regions on Earth due to its tectonic setting and explosive Holocene activity.

Autocorrelation‐Based Imaging of Crustal Discontinuities Including the Main Himalayan Thrust and Vp/Vs Ratio in the Jammu and Kashmir Himalaya

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Jammu and Kashmir Himalaya, located between the rupture zones of the 1905 Kangra and 2005 Kashmir earthquakes, represent a prominent “seismic gap” where understanding the subsurface structure is critical for seismic hazard assessment. This study presents new insights into the crustal structure of this region using teleseismic P‐wave coda ...
