Abstract

In order to make clear the structures of grounds which are liable to induce earthquake damage, the relations between seismic deformation of various objects and the structures of the grounds under them, and the intersectional angles between the epicentral direction and their longitudinal axes and between the epicentral direction and the deformational directions have been investigated on the basis of many examples of such damage. Various objects such as embankments on heterogeneous grounds, for example, grounds including inclined soft soil layer or made of soft soil layer with inclined bottom, or various objects straddling soft and hard grounds, are Liable to be largely destroyed by earthquakes. Additionally, it seems that epicentral direction is associated with ground structure and so such objects are more liable to be damaged by earthquake. This paper cites many examples of earthquake damage in which the damage seems to be due to a predominant seismic force working approximately at right angles to the epicentral direction.

Earthquake Damage Done at Right Angles to Epicentral Direction

St. Louis, Missouri

In order to make clear the structures of grounds which are liable to induce earthquake damage, the relations between seismic deformation of various objects and the structures of the grounds under them, and the intersectional angles between the epicentral direction and their longitudinal axes and between the epicentral direction and the deformational directions have been investigated on the basis of many examples of such damage. Various objects such as embankments on heterogeneous grounds, for example, grounds including inclined soft soil layer or made of soft soil layer with inclined bottom, or various objects straddling soft and hard grounds, are Liable to be largely destroyed by earthquakes. Additionally, it seems that epicentral direction is associated with ground structure and so such objects are more liable to be damaged by earthquake. This paper cites many examples of earthquake damage in which the damage seems to be due to a predominant seismic force working approximately at right angles to the epicentral direction.
