Comparison of displacements calculated for the fault model (dark line) with those estimated from data at 12 selected GPS stations. Locations of SE strainmeter station of KMU, GPS stations of GEONET (small circles) and temporary GPS station (big circle) are indicated in the central location map together with fault planes for two stages (dark grey then light grey) of slow slip. Comparison is carried out from 27 September to 25 October (UTC). GPS data was used only to constrain the length along strike of the slip model; down-dip dimensions and slip amplitude were determined using only KMU strain data. Nevertheless the agreement between the GPS data and model calculations is very good.
