TL;DR: In this article, the amplitude spectrum of the TEC time series showed peaks at 3.7 mHz, 4.8 mHz and 6.8mHz, and wavelet analysis showed that harmonic oscillations started at ∼16:25 UT and continued for ∼2.5 h.

Journal ArticleDOI
Radially anisotropic structure beneath the Shikoku Basin from broadband surface wave analysis of ocean bottom seismometer records
Akiko Takeo,Kiwamu Nishida,Takehi Isse,Hitoshi Kawakatsu,Hajime Shiobara,Hiroko Sugioka,Toshihiko Kanazawa +6 more
TL;DR: In this article, the authors analyzed broadband surface wave data from ocean bottom seismometers deployed in the Shikoku Basin in the northeastern Philippine Sea to determine the radially anisotropic uppermost mantle structure beneath this oceanic basin.
Journal ArticleDOI
Estimation of azimuthal anisotropy in the NW Pacific from seismic ambient noise in seafloor records
TL;DR: In this paper, the authors analyzed background surface waves in seismic ambient noise by cross-correlating continuous records of eight ocean bottom seismometers and nine differential pressure gauges deployed in the northwestern Pacific Ocean by the PLATE project.
Journal ArticleDOI
In Situ Characterization of the Lithosphere‐Asthenosphere System beneath NW Pacific Ocean Via Broadband Dispersion Survey With Two OBS Arrays
Akiko Takeo,Hitoshi Kawakatsu,Takehi Isse,Kiwamu Nishida,Hajime Shiobara,Hiroko Sugioka,Aki Ito,Hisashi Utada +7 more
TL;DR: In this article, the authors conducted a broadband dispersion survey by deploying two arrays of broadband ocean bottom seismometers in the northwestern Pacific Ocean at seafloor ages of 130 and 140 Ma.
