Spectral decay characteristics of ground motions for inland crustal earthquakes in Japan are examined. It is very important to clear spectral decay characteristics in hig [...]

Large permanent displacements, sometimes named “fling”, resulted from surface-rupturing faulting have been observed in some earthquakes, such as the 1999 Kocaeli, 199 [...]

High-cut frequency characteristics of ground motions for inland crustal earthquakes occurring in Japan are examined. It is very important to make clear spectral decay cha [...]

Studies that estimate low-frequency Q-value are very scarce. In most of them estimations are made by eye or by trial and error, without any systematic inversion approach. [...]

Average envelopes of small earthquakes represent a convenient basis for the construction of semi-empirical stochastic Green’s functions, used for prediction of future s [...]

This paper describes the generalized hybrid approach of wave injection for elastic linear case originated by Alterman and Karal (AK) in 1968 as a domain coupling technica [...]

High-rise buildings in mega-cities such as Osaka and Nagoya in Japan have a high probability of damage due to strong long-period ground motions from a great subduction ea [...]

In Mikawa area, the central area of Japan, many automobile plants and machine factories are locating there, unfortunately it is also one of the most risky regions for lar [...]

We developed a method for estimation of site effects in time function using observed records. So far, most of the empirical methods estimate the site effects with only am [...]

The Nankai Trough earthquakes which are subduction earthquakes with magnitude greater than 8 have occurred at intervals of 90 to 150 years. The probability of earthquake [...]
