Primary analysis on earthquake waveform characteristic of Songyuan M 5.8 earthquake swarm
摘要
Abstract
In this paper, we collected 23 earthquake waveform (MS ≥ 3.0) of Songyuan M 5.8 earthquake swarm in 2013. We made the phase identification to the collected earthquake waveform through the earthquake duration of vibrations, velocitys, periods, amplitude and so on. By analyses: The waveforms have the amplified activate to amplitude because the soil layer is thicker and the source is relatively shallow. It leads to surface wave development, longer duration of earthquake vibration. Earthquake phase mainly contain Pn, Sn, Pg, Sg, PmP, SmS. PmP and SmS can easily identified between 70 km to 110 km. Pn and Sn can clearly identified after about 150 km. With the increasing of the epicenter distance, the Sn becomes hardly identified after about 350 km.关键词
