Localization of b-values and maximum earthquakes; B chi to saidai jishin no chiikisei

Abstract

There is a thought that hourly and spacial blanks in earthquake activity contribute to earthquake occurrence probability. Based on an idea that if so, this tendency may appear also in statistical parameters of earthquake, earthquake activities in every ten years were investigated in the relation between locational distribution of inclined b values of a line relating to the number of earthquake and the magnitude, and the center focus of earthquakes which are M{ge}7.0. The field surveyed is the Japanese Islands and the peripheral ocean, and the area inside the circle with a radius of 100km with a lattice-like point divided in 1{degree} in every direction of latitude and longitude as center was made a unit region. The depth is divided by above 60km or below 60km. As a result, the following were found out: as to epicenters of earthquakes with M{ge}7.0 during the survey period of 100 years, many are in a range of b(b value){le}0.75, and sometimes they may be in a range of b{ge}0.75 in the area from the ocean near Izu peninsula to the ocean off the west Hokkaido; the position of epicenters in a range of b{le}0.75 seems not to come close to the center of  More>>
