RUPTURE MODEL OF THE GREAT 1923 KANNTO EARTHQUAKE INFERRED FROM GEODETIC AND TELESEISMIC DATA
|
�´˜^�i‰p�j�F
Geodetic and teleseismic data sets for the 1923 Kanto earthquake have been jointly inverted to obtain a rupture model that describes both temporal and spatial slip variations. Our analysis yields a seismic moment of 7-8 x 10�¡ dyne-cm (Mw=7.8-7.9) with a maximum slip of approximately 8 meters. The most concentrated slip is at fairly shallow depths in the central and western portions of the rupture beneath the Miura peninsula and the epicentral region north of Oiso.
