Abstract

The short-term effect of heavy rainfall on gPhone gravimeter observation at Zhengzhou Seismic Station is investigated. According to the observation data during Jul. 17–20, 2021, the corrected gravity residual reflects the gravimetric response caused by heavy rainfall. The observed gravity change is dominated by the local effect considering topographic effect on gravity. The deduced water depth near the observation station is about 300 mm.

中国郑州的 gPhone 重力计探测到的暴雨引起的重力变化

研究了强降雨对郑州地震台 gPhone 重力计观测的短期影响。根据 2021 年 7 月 17-20 日的观测数据，修正后的重力残差反映了暴雨引起的重力响应。考虑到地形对重力的影响，观测到的重力变化以局部效应为主。推算出观测站附近的水深约为 300 毫米。

期刊介绍： Journal of Earth Science (previously known as Journal of China University of Geosciences), issued bimonthly through China University of Geosciences, covers all branches of geology and related technology in the exploration and utilization of earth resources. Founded in 1990 as the Journal of China University of Geosciences, this publication is expanding its breadth of coverage to an international scope. Coverage includes such topics as geology, petrology, mineralogy, ore deposit geology, tectonics, paleontology, stratigraphy, sedimentology, geochemistry, geophysics and environmental sciences. Articles published in recent issues include Tectonics in the Northwestern West Philippine Basin; Creep Damage Characteristics of Soft Rock under Disturbance Loads; Simplicial Indicator Kriging; Tephra Discovered in High Resolution Peat Sediment and Its Indication to Climatic Event. The journal offers discussion of new theories, methods and discoveries; reports on recent achievements in the geosciences; and timely reviews of selected subjects.
