A.MohorovičIć探测到了地球最外层外壳、地壳和地幔之间的地震边界--“莫霍面”，这是对地震引起的地震波传播的深入了解的结果。这一莫霍面地震研究的简短历史主要基于Prodehl和Mooney(2012)对1850年至2005年利用受控震源进行地壳地震学研究的全球历史的全面概述。虽然作为研究地壳最上层的能源的爆炸技术，即所谓的“人工事件”，早在20世纪初就开始了，但它在研究整个地壳时才开始有效地使用，直到第二次世界大战结束。从1945年开始，可控震源地震学一直是研究地壳和壳幔边界--莫霍面--细节的主要方法。随后对可控震源地震学的历史及其开创性成果的描述以每十年为一个单独的章节，突出了这十年在数据采集、处理技术和解释方法方面取得的重大进展。自20世纪80年代末以来，利用远距离地震的被动地震学在地壳结构研究中发挥着越来越重要的作用。利用地震台下方地震波速度的不连续面上P波和SV波之间的转换的接收函数技术已被广泛应用于全球越来越多的永久和便携式宽带地震台站。接收函数研究补充了受控震源工作，改进了地理复盖范围，现在对了解地壳性质和莫霍面深度做出了重大贡献。
The detection of a seismic boundary, the “Moho”, between the outermost shell of the Earth, the Earth's crust, and the Earth's mantle by A. Mohorovičić was the consequence of increased insight into the propagation of seismic waves caused by earthquakes. This short history of seismic research on the Moho is primarily based on the comprehensive overview of the worldwide history of seismological studies of the Earth's crust using controlled sources from 1850 to 2005, by Prodehl and Mooney (2012). Though the art of applying explosions, so-called “artificial events”, as energy sources for studies of the uppermost crustal layers began in the early 1900s, its effective use for studying the entire crust only began at the end of World War II. From 1945 onwards, controlled-source seismology has been the major approach to study details of the crust and underlying crust–mantle boundary, the Moho. The subsequent description of history of controlled-source crustal seismology and its seminal results is subdivided into separate chapters for each decade, highlighting the major advances achieved during that decade in terms of data acquisition, processing technology, and interpretation methods.Since the late 1980s, passive seismology using distant earthquakes has played an increasingly important role in studies of crustal structure. The receiver function technique exploiting conversions between P and SV waves at discontinuities in seismic wavespeed below a seismic station has been extensively applied to the increasing numbers of permanent and portable broad-band seismic stations across the globe. Receiver function studies supplement controlled source work with improved geographic coverage and now make a significant contribution to knowledge of the nature of the crust and the depth to Moho.
