| 1 | SOURCE RADIATION AND RESPONSES OF WAVE PROPAGATION显示文摘Recordings of seismic waves propagating from earthquake source to a station at the earth’s surface are a system response function. The convolution operator in time domain can be simplified as a multiplication operator in frequency domain. We discuss in frequency domain the separation of source, path and site effects for global scaling of earthquake source radiation. Also discussed are source scaling model, faulting mechanism, and the H/V inversion problems with crustal and near surface structures. Gross features of apparent source spectra appear to be not much region dependent although there may be difference between tectonic styles within a region of tectonic mixture for which we need further study as data accumulate. Vertical spectra may be a better approach to approximate source radiation, as it has less crustal amplification effects than horizontal spectra. The H/V ratio is evidently a comprehensive indicator of amplification effects from near surface to deep structure. This gives it potential as an inversion tool to deduce site crustal structure. | CHEN Sheng zao 1 and Gail M Atkinson 2 (1.

| 2 | 加拿大艾伯塔省福克斯克里克附近潜在水压致裂诱发地震的震源分析显示文摘2015年6月13日,在加拿大西部艾伯塔省中部发生了4.4级(M_L)地震,这是2015年福克斯克里克附近页岩气勘探区发生的第三次有感地震事件。我们对该区域宽频带数据进行地震矩张量反演得到的结果显示为近垂直于断层走向的强走滑机制解。地震矩张量解的分解绝大多数是双力偶,而补偿线性向量偶极作用甚微(约20%)。此次地震的震源深度是3~4km,靠近沉积层底部,其矩震级(M=3.9)远小于最初报道的M_L值。震源位置、深度和震源机制有利于证明此次地震与迪韦奈页岩区域水压致裂作业之间存在潜在联系。 | Ruijia Wang Yu Jeffrey Gu Ryan Schultz Ahyi Kim Gail Atkinson 邹长桥(译) 朱玉萍(校) | 2017 | 世界地震译丛2017，48，3： | 1 |
| 3 | 加拿大西部诱发地震的主因是水压致裂而非废水注入显示文摘在美国中部石油和天然气生产过程中,由于废水的注入而引发了数以百计的小型地震,因此,有人将石油和天然气生产诱发的地震归因于废水注入。但是,在加拿大西部开展的研究结果表明,该地区地震是由生产过程中的水压致裂所致。 | 刘文浩 Gail M Atkinson David W Eaton Hadi Ghofrani | 2016 | 国际地震动态2016，37，5： | 0 |
