Occurrence Mechanism of Large Acceleration in KiK-net Seismic Records during Iwate–Miyagi Nairiku Earthquake in 2008
The KiK-net is a vertical array system, and seismic motions are recorded at the ground surface and in the borehole. With the peak acceleration of 24.5 m/s2 at AKTH04 (EW) and 38.7 m/s2 at IWTH25 (UD) during the Iwate–Miyagi Nairiku earthquake in 2008, the occurrence mechanism of large accelerations is investigated by the non-stationary Fourier spectra and the double integrated displacement prof...
متن کاملStrong motions observed by K-NET and KiK-net during the 2016 Kumamoto earthquake sequence
The nationwide strong-motion seismograph network of K-NET and KiK-net in Japan successfully recorded the strong ground motions of the 2016 Kumamoto earthquake sequence, which show the several notable characteristics. For the first large earthquake with a JMA magnitude of 6.5 (21:26, April 14, 2016, JST), the large strong motions are concentrated near the epicenter and the strong-motion attenuat...
متن کاملEstimating near-surface shear wave velocities in Japan by applying seismic interferometry to KiK-net data
We estimate shear-wave velocities in the shallow subsurface throughout Japan by applying seismic interferometry to the data recorded with KiK-net, a strongmotion network in Japan. Each KiK-net station has two receivers; one receiver on the surface and the other in a borehole. By using seismic interferometry, we extract the shear wave that propagates between these two receivers. Applying this me...
متن کاملFuzzy logic-based attenuation relationships of strong motion earthquake records
Fuzzy logic techniques have been widely used in civil and earthquake engineering applications in the past four decades. However, no thorough research studies were conducted to use them for deriving attenuation relationships for peak ground accelerations (PGA). This paper is an attempt to fill this gap by employing a fuzzy approach with fuzzy sets for earthquake magnitude and distance from sourc...
