摘要

Abstract

Data of earthquakes and explosions above ML 2.5 recorded by the Hainan earthquake network since 2008 have been collected. Using the Brune disk model, the hypocenter parameters are calculated. We found that the hypocenter parameters of earthquakes and explosions are difference:Most of the corner frequencies of earthquakes are larger than those of blasting, the stress drop of the earthquake is greater than 1, while the stress drop of blasting is less than 1; Most of the focal dimensions of earthquakes are smaller than those of blasting. For a sensible suspected explosion event, its frequency, stress drop and focal dimension can be used to determine the type of the event. This event was a natural earthquake, consistent with previous research results. Thus it can be seen, the hypocenter parameter has practical significance in the earthquake quick report, daily analysis and the determination of the event type.
