Comparison of model based on conjectural fault movements and intrusions and actual GPS observations

(notes)
The fixed station at Yamanashi Otsuki (93064) used the observation stations marked by arrows on the map (24 stations X 3 components).
The fault parameters determined in the EIC Seismology Notes (No. 81; Kikuchi, Yamanaka), are estimates only of position and slip amount (presumed aseismic slip).
The hypocenters used were based on the results of data processing by the Meteorological Agency and the Ministry of Science and Technology (July 6th to 12th).
