Tần số góc và kích thước phá hủy động đất trận động đất Điện Biên

Abstract

Summary
Corner frequency and rupture area of Dienbien earthquake
one of the most important parameters of the earthquake source model is the affected area at the source. Generally, this area is determined by
observation instruments or by estimation from calculations based on equations related to the released energy such as magnitude. Brune (1970) considered this affected area is a function of the corner frequency. In this paper, we undertake the calculations of the earthquake damaged area at Dien Bien and a few aftershocks… by determining this corner frequency of these earthquakes
