摘要

Abstract > The 2011 M <sub> w </sub> 9.0 Tohoku‐Oki megathrust earthquake accompanied coseismic and postseismic displacements around the eastern Eurasian continental plate. Noise cross correlations produced transient seismic waveforms along interstation paths in the Korean Peninsula. We measured the traveltime changes of the fundamental mode Rayleigh waves over the range of 0.03–0.08?Hz after the megathrust earthquake. The temporal seismic velocity changes in the lower crust were assessed from the traveltime changes. The traveltimes increased instantly after the megathrust earthquake and were gradually recovered over several hundreds to thousands of days. The instant shear wave velocity decreases ranged between 0.731 (±0.057)% and 4.068 (±0.173)%. The temporal medium perturbation might be caused by the transient uniaxial tensional stress due to the coseismic and postseismic displacements. The medium properties may be recovered by progressive stress field reconstruction. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“main”XML：lang =“en”XML：ID =“Grl56612-Abs-abs-abs-0001”> <标题类型=“main”>抽象</ title> > 2011 m </ I> <sub> w </ i> </ sub> 9.0 Tohoku-oki Megathrust地震伴随着欧亚大陆板块东部的电影发射和后近。噪声交叉相关产生沿着朝鲜半岛的横向路径产生的瞬态地震波形。我们在巨大地震后测量了基本模式瑞利波的行程变化在0.03-0.08的范围内。从旅行时间改变评估较低地壳中的时间地震速度变化。巨大地震后，旅行次立即增加，逐渐恢复数百至数千天。即时剪切波速度降低0.731（±0.057）％和4.068（±0.173）％。颞介质扰动可能是由于因皮塞和后骨位移而引起的瞬态单轴张力引起。可以通过渐进应力场重建来回收培养基。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-23539/'>《Geophysical Research Letters》</a> <b style="margin: 0 2px;">|</b><span>2017年第21期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hong Tae‐Kyung&option=202" target="_blank" rel="nofollow">Hong Tae‐Kyung;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lee Junhyung&option=202" target="_blank" rel="nofollow">Lee Junhyung;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Chi Donggeun&option=202" target="_blank" rel="nofollow">Chi Donggeun;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Park Seongjun&option=202" target="_blank" rel="nofollow">Park Seongjun;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Department of Earth System SciencesYonsei UniversitySeodaemun‐gu Seoul South Korea;</p> <p>Department of Earth System SciencesYonsei UniversitySeodaemun‐gu Seoul South Korea;</p> <p>Department of Earth System SciencesYonsei UniversitySeodaemun‐gu Seoul South Korea;</p> <p>Department of Earth System SciencesYonsei UniversitySeodaemun‐gu Seoul South Korea;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/163.html" title="地球物理学">地球物理学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=seismic velocity&option=203" rel="nofollow">seismic velocity;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=backarc crust&option=203" rel="nofollow">backarc crust;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=megathrust earthquake&option=203" rel="nofollow">megathrust earthquake;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=medium perturbation&option=203" rel="nofollow">medium perturbation;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Korean Peninsula&option=203" rel="nofollow">Korean Peninsula;</a> </p> <div class="translation"> 机译：地震速度;BACKARC CRUST;MEGATHRAST地震;中扰动;朝鲜半岛;
