| Research Abstract |
I conducted continuous GPS observations in the Bungo channel region where dip-angle of the Philippine Sea slab and strike of the plate boundary change sharply. Using a newly developed power-uninterruptible and data self-downloading GPS observation system, I made clear spatial pattern of crustal deformation between Shikoku and Kyushu and also detected transient deformation associated with slow slip event that started at the end of 2009. The observation system developed in this study has been applied to the continuous monitoring of the Sumatra fault, Indonesia.
