Investigation of Pressure Source Geometries Using Finite Element Method for Ground Deformation at Around Aira Caldera

Autor: MIKI, Daisuke, TSUTSUI, Tomoki, IGUCHI, Masato

Publikováno v: 京都大学防災研究所年報. B. 65:42-47

We calculated the ground deformation due to differently shaped rotational ellipsoidal pressure sources beneath the Aira caldera using a FEM model. Deeper horizontal pressure sources seem to be consistent with the observed data, as well as that expect

Publikováno v: 京都大学防災研究所年報. B. 65:35-41

We obtain a three-dimensional seismic velocity structure below the Aira caldera at a depth shallower than 45km, southwest Japan, applying seismic tomography inversion method to analyze 16, 110 P-wave onsets and 11, 838 S-wave onsets of natural earthq

A Fundamental Experiment for the Long-term Sustainable Seismic Reflection Survey of Aira Caldera

Autor: TSUTSUI, Tomoki, TAMEGURI, Takeshi, MIKI, Daisuke, IGUCHI, Masato, SHINOHARA, Masanao

Publikováno v: 京都大学防災研究所年報. B. 64:86-100

A fundamental experiment has been performed to test feasibility of the long-term sustainable seismic reflection survey of underground activity in the depth of Aira Caldera. The experiment is the first attempt and is designed as peer-to-peer operation

Estmate of Magma Supply Rate Beneath Aira Cardera, Kyushu, Japan; Inferred from GNSS Observation

Autor: MIKI, Daisuke, TSUTSUI, Tomoki, IGUCHI, Masato

Publikováno v: 京都大学防災研究所年報. B. 64:101-107

We applied a composite analysis of spherical pressure source at around Aira caldera, Kyushu Japan. Horizontal displacements obtained from GNSS observations and vertical displacements from leveling survey, during 2017 to 2019, were used for the analys

The Seismic Reflectors Beneath Aira Caldera

Autor: TSUTSUI, Tomoki, TAMEGURI, Takeshi, IGUCHI, Masato

Publikováno v: 京都大学防災研究所年報. B. 63:118-135

Seismic reflectors at the depth of Aira Caldera are presented through seismic array analysis of the later arrivals in the controlled-source seismograms across northern Kagoshima Bay on November 2008. Though the first arrivals with a characteristic pa

Publikováno v: 京都大学防災研究所年報. B. 58:71-75

We conducted the precise leveling survey in Sakurajima volcano in November 2014, in order to evaluate the vertical ground deformation associated with the recent eruptive activity. The measured survey data are compared with those of the previous surve

We conducted an active seismic experiment in and around Aira caldera in December 2013, five years after a similar experiment conducted in 2008 in order to detect temporal changes of seismic structure beneath Sakurajima volcano and Aira caldera. We de
