Cooperative measurements of microtremors in the north-eastern region of Nishinomiya city, Hyogo Pref.; Nishinomiyashi hokutobu ni okeru joji bido no godo kansoku

Abstract

For the purpose of generally grasping space distribution of ground vibration characteristics, cooperative measurements were conducted in a wide area, mainly in the area stricken by the M7 earthquake. Forty-five organs such as governmental institutes, universities, and private company institutes participated in the measurements which were conducted at 1967 measuring points. The area which the author is in charge is an area from the north of Nishinomiya City to the south of Takarazuka City. The area is relatively far from the hypocenter area, but the magnitude is 7 there and damage was concentrated. The measurements were made by each independent team from August 29 to September 1, 1995. As a result of spectral measurements of NS, EW and UD components, conspicuous peaks were seen in an extent of 1.5 sec. cycle in almost all measuring points and components. Further, in spectra of horizontal motion components of A measuring point group, conspicuous peaks were seen in an extent of 0.15-0.5 sec. cycle, and in those in B and C measuring point groups, in an extent of 0.35-0.5 sec. cycle. In upper/lower motion components, conspicuous peaks were seen in an extent of 0.3 sec. cycle in A measuring point group. 4 figs.
