On a large magmatic fluid reservoir oblique to the volcanic front in the southern part of NE Japan revealed by the magnetotelluric survey

Autor: Dieno Diba, Makoto Uyeshima, Masahiro Ichiki, Shin’ya Sakanaka, Makoto Tamura, Yiren Yuan, Marceau Gresse, Yusuke Yamaya, Yoshiya Usui

Publikováno v: Earth, Planets and Space, Vol 75, Iss 1, Pp 1-10 (2023)

Abstract Many active volcanoes and various types of seismic activities exist in the southern part of the Northeast Japan subduction zone. One of the geologically most interesting features in this area is the sequential explosive eruptions of a group

Anatomy of active volcanic edifice at the Kusatsu–Shirane volcano, Japan, by magnetotellurics: hydrothermal implications for volcanic unrests

Autor: Kuo Hsuan Tseng, Yasuo Ogawa, Nurhasan, Sabri Bülent Tank, Naoto Ujihara, Yoshimori Honkura, Akihiko Terada, Yoshiya Usui, Wataru Kanda

Publikováno v: Earth, Planets and Space, Vol 72, Iss 1, Pp 1-11 (2020)

Abstract We aimed to perform three-dimensional imaging of the underlying geothermal system to a depth of 2 km using magnetotellurics (MT) at around the Yugama crater, the Kusatsu–Shirane Volcano, Japan, which is known to have frequent phreatic erup

Publikováno v: Earth, Planets and Space, Vol 70, Iss 1, Pp 1-10 (2018)

Abstract On 29 June 2015, a small phreatic eruption occurred at Hakone volcano, Central Japan, forming several vents in the Owakudani geothermal area on the northern slope of the central cones. Intense earthquake swarm activity and geodetic signals c

Delineating fluid distribution beneath the southern Tohoku, Northeast Japan, with a joint inversion of magnetotelluric and geomagnetic transfer functions

Autor: Dieno Diba, Makoto Uyeshima, Masahiro Ichiki, Shin'ya Sakanaka, Makoto Tamura, Yoshiya Usui

The southern part of Tohoku, Northeast Japan, is an area with significant in-land activities owing to the ongoing subduction mechanism. Among these are active volcanoes distributed on the volcanic front and back-arc, active faults throughout the area

New 3-D Combined Inversion Scheme Using Response Functions Free From Galvanic Distortion

Autor: Makoto Uyeshima, Yoshiya Usui

The combined inversion using distortion-free response functions is an effective approach to robustly estimate the 3-D electrical resistivity structure against the distortions caused by near-surface resistivity anomalies. However, previous combined in
