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. 65:48-66

Experimental assessments for a pillar-coupled electric benchmark platform at anchor are reported, which made on a test platform. Development of a geodetic platform at the center of flooded calderas have been highly demanded to improve the monitoring

Tilt and Strain Change Before and After the Explosion at Minami-dake, Sakurajima, in 2017

Autor: HOTTA, Kohei, IGUCHI, Masato

Publikováno v: 京都大学防災研究所年報. B. 61:324-329

Deformation source associated with each eruption at Sakurajima have been estimated beneath Minami-dake for each eruption. Deformation sources for mid-long term magma intrusion event were estimated beneath Aira caldera, Kita-dake and Minami-dake. A ne

Characteristics of Pyroclastic Flow at Sakurajima Volcano's Showa Crater

Autor: TAMEGURI, Takeshi, IGUCHI, Masato

Publikováno v: 京都大学防災研究所年報. B. 61:312-317

Eruptions at the Showa crater become active since 2008 and are sometimes accompanied with small pyroclastic flows. It is important to understand the mechanism of generation of the pyroclastic flow for volcanic disaster prevention. We research charact

Publikováno v: 京都大学防災研究所年報. B. 56:197-206

We analyzed GPS data during 1998-2006 to make clear process of magma accumulation and movement of Sakurajima volcano prior to eruptive activity at the summit crater in 1999 and eruptive activity at Showa crater resumed in 2006. Obtained deformation r
