“…The estimated size of the rupture area of the 1973 earthquake (80 km 9 80 km) was obtained from the tsunami waveform inversion where the slip amount was larger than 1.0 m. The 1963 Kurile earthquake occurred northeast of the 1969 earthquake. Slip distribution of the 1963 earthquake was estimated using tsunami waveform data and the total seismic moment of 3.9 9 10 21 Nm (M w 8.3) was estimated from slip distribution (Ioki and Tanioka 2011). The estimated rupture area having a slip amount of more than 1.0 m was 300 km 9 150 km.…”

“…These events considered in [7,8], also parameters of those source models reviewed in [9,10,11]. The exact match of observed and simulated tsunami heights is not necessary, as shown in [12] only height ratio estimates are enough for the point where tsunami height is known.…”

“…To conduct detailed simulations in bays of Shikotan Island and refine calculation in Yuzhno-Kurilskaya Bay and Kitoviy Bay of Iturup Island the 15-arcsecond grid has been interpolated for coupling with digitized bathymetries of bays to 2-arcsecond resolution. The seismological finite-fault data of tsunamigenic earthquakes were taken from USGS and articles devoted to old events of 1958-1994 [15,9,10,11,16]. After carrying out calculations of the propagation of all significant tsunamis, the numerical waveforms in each point along the isobath of about 8 m were processed with a special transformation allowing one to estimate the wave height on the shore with assumption the one-dimensional nonlinear rolling.…”

The tsunami-zoning map (possible tsunami heights of a frequency of 1 event within 50 and 100 years) for the coast of the South Kuril Islands have been updated (former map have been developed in 2006). The update is based on the development of the tsunami-activity model, mainly due to the increase of the number of basic coastal locations (from 18 to 62) for which the parameters of the recurrence function were estimated, as well as on the modernization of the numerical model. Serious progress in simulations was achieved in setting the initial conditions, using the seismic tsunami source model. Field surveys on the coast to search for traces of historical and paleotsunami, as well as qualitative documentation of the Tohoku tsunami manifestations allowed to clarify the model of tsunami-activity in Southern Kuril Islands. The sufficiently large amount of data in this case (which is generally untypical for the tsunami) allowed authors, to apply the statistical approach for evaluation of the tsunami hazard distribution along the coast. Estimates of tsunami heights were spread from the basic coastal locations to adjacent parts of the coast using detailed simulation of all significant tsunamis and calculating wave heights at the shoreline. The detailed maps of tsunami-hazard at scale 1:100,000 have been made for the settlements of Yuzhno-Kurilsk, Kurilsk, Malokurilskoe, and Krabozavodskoe.

“…Ioki and Tanioka (2011) obtained the slip distribution of the 1963 Etorof earthquake (M8.2) by using the tsunami data. The quiescence area is well matched with the subfaults with the slip of 0.5 m or larger obtained by Ioki and Tanioka (2011). It is not clear whether this seismic quiescence ended or not.…”

Abstract-An earthquake catalog created by the International Seismological Center (ISC) was analyzed, including 3898 earthquakes located in and around Japan between January 1964 and June 2012 shallower than 60 km with the body wave magnitude of 5.0 or larger. Clustered events such as earthquake swarms and aftershocks were removed from the ISC catalog by using a stochastic declustering method based on Epidemic-Type Aftershock Sequence (ETAS) model. A detailed analysis of the earthquake catalog using a simple scanning technique (ZMAP) shows that the long-term seismic quiescences lasting more than 9 years were recognized ten times along the subduction zone in and around Japan. The three seismic quiescences among them were followed by three great earthquakes: the 1994 Hokkaido-toho-oki earthquake (M w 8.3), the 2003 Tokachi-oki earthquake (M w 8.3), and the 2011 Tohoku earthquake (M w 9.0). The remaining seven seismic quiescences were followed by no earthquake with the seismic moment M 0 C 3.0 9 10 21 Nm (M w 8.25), which are candidates of the false alarm. The 2006 Kurile Islands earthquake (M w 8.3) was not preceded by the significant seismic quiescence, which is a case of the surprise occurrence. As a result, when limited to earthquakes with the seismic moment of M 0 C 3.0 9 10 21 Nm, four earthquakes occurred between 1976 and 2012 in and around Japan, and three of them were preceded by the long-term seismic quiescence lasting more than 9 years.
