Cause of destructive strong ground motion within 1–2 s in Mukawa town during the 2018 M w 6.6 Hokkaido eastern Iburi earthquake [PDF]
We investigated the cause of destructive ground motion during the 2018 Hokkaido eastern Iburi earthquake. We conducted strong motion observations of aftershocks and microtremors and the surface wave method in the damaged areas of the town of Mukawa ...

Geodetically estimated location and geometry of the fault plane involved in the 2018 Hokkaido Eastern Iburi earthquake [PDF]
By applying the InSAR method to ALOS-2 SAR data acquired before and after the 2018 Hokkaido Eastern Iburi earthquake, the ground displacement fields were successfully mapped. Ground deformation is distributed on the eastern side of an active fault, known

Arc-arc collision caused the 2018 Eastern Iburi earthquake (M 6.7) in Hokkaido, Japan. [PDF]
AbstractInland crustal earthquakes usually occur in the brittle upper crust (0–20 km depths), but the 6 September 2018 Eastern Iburi earthquake (M 6.7) took place in southern Hokkaido with a focal depth of ~37 km, causing 41 fatalities and serious damage to the local infrastructure.

Abstract This paper studies the effect of structure–soil–structure interaction (SSSI) on the seismic response of neighboring structures with shallow foundations on liquefiable sand. The problem is studied through coupled hydromechanical analyses. Nonlinear soil response is modeled with PM4Sand, calibrated on the basis of soil element tests of Hostun ...

“q‐NAVI”: A case of market‐based implementation of structural health monitoring in Japan
In Japan, structural health monitoring (SHM) of building structures began in the 1950s, but, until recently, its widespread use was not realized. A new trend arrived a few years ago, and currently over 850 buildings have SHM systems installed. The most recent SHM systems have been installed voluntarily by owners in the private sector; that is, the ...
