Improvement of Attenuation Formula of Earthquake Ground Motion in Consideration of the Volcanic Front
|
´˜^i‰pjF |
The attenuation relation of earthquake strong ground motion, which is predictable in wide area, is important. In this study, it is tried that the attenuation formula based on positional relation of volcanic front (VF), hypocenter and obser-vation point is made. By requiring the regression formula by the division of hypocentral distance in the volcanic front, the attenuation formula, which the effect of the large-scale attenuation structure reflected, was obtained.
