SEA LEVEL SIGNALS CORRECTION FOR THE 2011 TOHOKU TSUNAMI

The paper analyses the signals measured during the M9.0 Tohoku Tsunami in order to identify the effect of the subsidence on the measurements and determine correction factors to be applied to the measurements. The objective is to have a coherent set of measurements that can allow the estimation of the source term of the event. The analysis shows that the subsidence has a notable influence on the measurements where the deformation is large and that taking into account the deformation in the signals may improve notably the estimation of the initial deformation.
