Exploring fluid distribution along subduction zones is an important issue because the fluid is considered to control the occurrence of earthquakes. One of the effective strategies to estimate fluid content is retrieving receiver functions (RFs) from seismograms, but in the case of ocean-bottom seismometers (OBSs), noisy P-wave reverberations within the seawater column make such an analysis difficult. The author therefore developed a novel technique to suppress the water reverberations, which allows obtaining the fluid distribution data along a wide depth range on the plate interface. .? This thesis first presents the new technique, called the water layer filter method, and demonstrates its efficiency by using both synthetic and observation data. Then, using the method, a receiver functionimage of the Philippine Sea Plate is constructed to reveal dehydration processes of the subducting oceanic crust around the Kii Peninsula. Finally, the author performs high-frequency receiver function inversion a | | 出版日期 | Book 2018 | | 關(guān)鍵詞 | Subduction zone; Fluid distribution; Megathrust fault; Receiver function analysis; Ocean-bottom seismome | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-10-8174-3 | | isbn_softcover | 978-981-13-4085-7 | | isbn_ebook | 978-981-10-8174-3Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer Nature Singapore Pte Ltd. 2018 |
