Detailed landslide information from Large landslides at the northeastern margin of the Bayan Har Block, Tibetan Plateau, China

, 2018
Large landslides (volume greater than or equal to 106 m3) usually have disastrous consequences and clearly influence the evolution of the local landscape. In this study, a detailed investigation of large landslides, across 20 towns over an area of 5000 km2, was carried out on the northeastern margin of the Bayan Har Block, at the eastern margin of the ...

Miniaturized Droplet‐Based Adaptation of the Ames Test for High‐Throughput Mutagenicity Assessment

Journal of Applied Toxicology, EarlyView.
ABSTRACT This work presents the first demonstration of a tube‐based droplet microfluidic implementation of the Ames test, bridging single‐droplet resolution with regulatory genotoxicity testing. The Ames test is a cornerstone assay for detecting mutagenicity, but conventional plate‐ and well‐based formats suffer from high reagent consumption, low ...

基于库仑应力改变和地震活动性研究巴颜喀拉块体周缘强震序列的触发关系及其构造意义

Dizhen xuebao, 2018
自本世纪以来，青藏高原巴颜喀拉块体周缘密集地发生了7次MW≥6.5强震事件，包括伤亡惨重的2008年汶川MW7.9地震和2017年九寨沟MW6.5地震。本文根据这7次强震事件中先前地震对后续地震的库仑应力改变（dCFS）的计算结果，结合基于ETAS模型得到的背景地震活动性的变化结果，研究了强震间的触发关系，以试图解释发生在环巴颜喀拉块体的几次强震的发震机理并探讨其构造意义。结果表明，各个强震的库仑应力变化与其造成的背景地震活动性变化呈正相关，并且在这7次强震中，汶川地震对芦山地震有显著的触发作用 ...

Stress Evolution Before and After the 2021 Mw 7.3 Maduo Earthquake in Northeastern Tibet and Its Influence on Seismic Hazards

Earth and Space Science, 2022
The 2021 Mw 7.3 Maduo earthquake ruptured the Kunlun Pass‐Jiangcuo fault (KPJF) in the Bayan Har Block (BHB) in northeastern Tibet. To explore the reasons behind the Maduo earthquake and the seismic hazards that followed this event in the BHB, we ...
