基于张衡一号01星监测到的2019-2022年中国大陆MS≥6.0地震前电离层扰动
The Ionospheric Disturbances Prior to the MS≥6.0 Earth-quakes in Chinese Mainland from 2019 to 2022 Monitored by the China Seismo-Electromagnetic Satellite-01
摘要
Abstract
Based on the data of electron density(Ne)data acquired by the China Seismo-Electromagnetic Satellite-01(CSES-01),the ionospheric disturbances within 15 days prior to MS≥6.0 earthquakes in Chinese mainland from 2019 to 2022 were analyzed.It is found that the probability of Ne anomalies occurring before earthquakes is relatively high,mainly within one week before the earthquakes,with positive anomalies predominanting.In addition,based on the seismic precursor anomalies data,it is believed that the Maduo MS7.4 earthquake in 2021 may have affected the ionosphere through the acoustic and electromagnetic channels described by the lithosphere-atmosphere-ionosphere coupling(LAIC)model.关键词
