Seismic observation using distributed acoustic sensing around the Tsugaru Strait at the Japan and Kuril Trenches, northeastern Japan

Autor: Satoru Baba, Eiichiro Araki, Takashi Yokobiki, Kei Kawamata, Keisuke Uchiyama, Takuji Yoshizuka

Publikováno v: Earth, Planets and Space, Vol 76, Iss 1, Pp 1-12 (2024)

Abstract As megathrust earthquakes often have source areas in offshore regions, offshore seismic observations are important. However, the detection capability and resolution of offshore earthquake locations are low owing to the small number of perman

Observation of Shallow Slow Earthquakes by Distributed Acoustic Sensing Using Offshore Fiber‐Optic Cable in the Nankai Trough, Southwest Japan

Autor: Satoru Baba, Eiichiro Araki, Yojiro Yamamoto, Takane Hori, Gou Fujie, Yasuyuki Nakamura, Takashi Yokobiki, Hiroyuki Matsumoto

Publikováno v: Geophysical Research Letters, Vol 50, Iss 12, Pp n/a-n/a (2023)

Abstract Off Cape Muroto area, along the Nankai Trough in southwest Japan, is a typical area with adjacent occurrences of slow and megathrust earthquakes. High‐resolution monitoring of slow earthquakes is necessary to understand tectonic conditions

Characteristics of shallow tremor waveforms observed by distributed acoustic sensing using offshore fiber-optic cable at the Nankai Trough, southwest Japan

Autor: Satoru Baba, Eiichiro Araki, Yojiro Yamamoto, Takane Hori, Gou Fujie, Yasuyuki Nakamura, Takashi Yokobiki, Hiroyuki Matsumoto

Distributed acoustic sensing (DAS) measurement, which uses a fiber-optic cable as a strain sensor, allows us spatially high-density observation than seismometers; therefore, DAS has been widely used for seismic observations recently. We conduct DAS m

Spatial variation in shallow slow earthquake activity in Hyuga-nada, southwest Japan

Autor: Satoru Baba, Shunsuke Takemura, Kazushige Obara, Akiko Takeo, Yusuke Yamashita, Masanao Shinohara

Hyuga-nada, off the Pacific coast of Kyushu along the Nankai Trough in southwest Japan, is one of the most active slow earthquake regions around Japan. We estimated the energies of shallow tremors and moments of shallow very low frequency earthquakes

Detectability analysis of very low frequency earthquakes: Methods and application in Nankai using F-net and DONET broadband seismometers

Autor: Shunsuke Takemura, Satoru Baba, Suguru Yabe, Yusuke Yamashita, Katsuhiko Shiomi, Takanori Matsuzawa

For a more quantitative discussion of slow earthquake activity, we evaluated the detectable limits of very low frequency earthquakes (VLFEs), which are seismic slow earthquakes observed in very low frequency (< 0.05 Hz) bands, in the Nankai subductio

Spatiotemporal variations of shallow very low frequency earthquake activity southeast off the Kii Peninsula, along the Nankai Trough, Japan

Autor: Shunsuke Takemura, Kazushige Obara, Katsuhiko Shiomi, Satoru Baba

Cross-correlation analysis was applied to long-term onshore broadband records from April 2004 to March 2021 to detect and relocate shallow very low frequency earthquakes (VLFEs) southeast off the K...

Shallow Slow Earthquake Episodes Near the Trench Axis Off Northern Costa Rica

Autor: Satoru Baba, Akiko Takeo, Kazushige Obara, Geoffrey A. Abers, Shunsuke Takemura

Slow earthquakes are generally distributed in regions surrounding seismogenic zones along the plate boundaries of subduction zones. In the Costa Rica subduction zone, large regular interplate earth...

Slow Earthquakes Illuminating Interplate Coupling Heterogeneities in Subduction Zones

Autor: Satoru Baba, Shunsuke Takemura, Kazushige Obara, Akemi Noda

Publikováno v: Geophysical Research Letters. 47

Slow earthquakes are mainly distributed in the vicinity of seismogenic zones of megathrust earthquakes and relationships between both types of earthquakes are expected. We examined the activity of ...
