Black arrows indicate the estimated slip deficit rate distribution by geodetic data inversion.
Black arrows shown in the lower rectangle indicate the estimated slip deficit rate distribution by geodetic data inversion.
Conversely, if no slip deficit is detected by geodetic data inversion, it is highly probable that no asperity exists.
Conversely, Fig. 8(c) shows that the weighted center of the slip deficit can be estimated approximately by geodetic data inversion.
In the opposite sense, if no slip deficit is detected by geodetic data inversion, there is no asperity on the plate interface.
(c) "Estimated MDR" is the moment of the slip deficit rate distribution estimated by the geodetic data inversion analysis.
We evaluated the physical state of the plate interface estimated from the interseismic crustal deformation rate, combining the forward simulation of crustal deformation because of plate subduction and geodetic data inversion analysis.
Source parameters for the total amount of deflation during the three sub-Plinian eruptions and the magma effusion are also estimated by Ueda et al. (2013) and Nakao et al. (2013) by using geodetic data.
Our synthetic test of the case that postseismic slip distributes around the coseismic slip shows that the coseismic slip is reasonably well resolved by the geodetic data.
They combined the temporal volumetric change of the magma chamber estimated by the geodetic data during the eruption with that of accumulating lava in the crater measured by Synthetic Aperture Radar (SAR) images during the continuous lava effusion.
