内容記述 | The Wadati-Diagram, which is successively obtained through a mini-computer system, is applied to evaluate the travel time data of micro-earthquakes in the Kanto region, central Japan. Several useful characteristics with respect to the travel time pertinent to the station location and the gradients of the Wadati-diagram pertinent to Vp/Vs, are found. Vp/Vs is greater than √3 in the region under Ibaraki prefecture and Kashima-nada. | |||||
