The historical geodetic and teleseismic data are jointly inverted for the rupture process of the 1923 Kanto earthquake together with the strong motion data recently discovered. The resultant slip distribution shows two asperities (areas of large slips) on the fault plane with a total seismic moment of 1.1 ⊙ 1021 Nm (Mw 8.0). The asperity in the shallow central portion of the fault is larger with maximum slip of approximately 10 m than the one in the hypocentral region. The recovered slip… 
Rupture process of the 1946 Nankai earthquake estimated using seismic waveforms and geodetic data
The rupture process of the 1946 Nankai earthquake (MJMA 8.0) was estimated using seismic waveforms from teleseismic and strong motion stations together with geodetic data from leveling surveys and
The source model and recurrence interval of Genroku-type Kanto earthquakes estimated from paleo-shoreline data
In the southern Kanto region of Japan, where the Philippine Sea plate is descending at the Sagami trough, two different types of large interplate earthquakes have occurred repeatedly. The 1923
Rupture Processes of the 2011 Tohoku-Oki Earthquake and Its Two M7-Class Aftershocks Derived Using Curved Fault Models
The MJMA9.0 Tohoku-Oki mega-thrust earthquake was followed by two large interplate earthquakes (MJMA7.4 and 7.6) that occurred around the northern and southern ends of the mainshock source area
The 1923 Kanto earthquake reevaluated using a newly augmented geodetic data set
[1] This study revisits the mechanism of the 1923 Ms = 7.9 Kanto earthquake in Japan. We derive a new source model and use it to assess quantitative and qualitative aspects of the accommodation of
Sediment deformation in eastern Sagami Bay revealed by high-density seismic reflection survey
Sagami Bay is known as a seismogenic area occurring large earthquakes repeatedly with M > 7 at the boundary between the Philippine Sea plate and the overriding northeastern Japan with the Quaternary
Scaling of characterized slip models for plate-boundary earthquakes
We characterized source rupture models with heterogeneous slip of plate-boundary earthquakes in the Japan region. The slip models are inferred from strong-motion, teleseismic, geodetic, or tsunami
Migration of earthquakes with a small stress drop in the Tanzawa Mountains, Japan
A cluster of earthquake activity took place beneath the Tanzawa Mountains at a depth of 20 km during the end of January 2012. The activity began at 22:39 UT on January 27 and included 78 earthquakes
Active deformation of Sagami Bay triggered by approach of the Izu island arc
Sagami Bay in central Japan is known as the seismogenic and tsunamigenic zone of the 1703 and 1923 Kanto earthquakes that caused devastating damage in the Tokyo metropolitan area. However, the


Fault mechanism and recurrence time of major earthquakes in southern Kanto district, Japan, as deduced from coastal terrace data
The southern Kanto region has had two shocks of magnitude 8 or greater during the past 1,000 years. They were the 1703 and 1923 earthquakes, which occurred along the Sagami trough, a northeastern
Variable-slip rupture model of the great 1923 Kanto, Japan, earthquake: geodetic and body-waveform analysis
Abstract The available geodetic and teleseismic data sets for the 1923 Kanto earthquake ( M s = 8.1) have been combined into a joint inversion for both temporal and spatial slip variations. We
Joint Inversion of Near- and Far-field Waveforms and Geodetic Data for the Rupture Process of the 1995 Kobe Earthquake
The geodetic data, strong-motion waveforms, and far-field waveforms from the 1995 Kobe earthquake (MJMA 7.2) were inverted to determine the rupture process. The geodetic data, including the
Statical and dynamical study on faulting mechanism of the 1923 Kanto earthquake.
An inverse method to find optimum fault parameters from geodetic data with random errors is extended so as to be applicable to a case of the data including a systematic error caused by movements of
Source rupture process of the 2003 Tokachi-oki earthquake determined by joint inversion of teleseismic body wave and strong ground motion data
The spatio-temporal slip distribution of the 2003 Tokachi-oki, Japan, earthquake was estimated from teleseismic body wave and strong ground motion data. To perform stable inversion, we applied
