摘要:
2023年2月5日和11日广东三水、河源相继发生了3.2和4.3级地震,震后整理发现广东地区的重力、部分地倾斜、水位等记录到了同震响应波或水震波。分析了地形变、地下流体学科观测资料同震波形的表现形态及特征。从各仪器记录曲线来看,在同震响应后基本能快速恢复到震前正常观测形态,证明了广东省内地球物理观测设备运行的稳定性和可靠性。通过对各观测仪器地震同震响应和记录能力分析,以期对进一步深入研究以上2次地震对广东省未来地震趋势的影响有所帮助。
Abstract:
The M3.2 and M4.3 earthquakes occurred successively in Sanshui and Heyuan of Guangdong Province on February 5th and 11th,2023. After the earthquakes,it was found that the gravity,partial ground tilt and water level in Guangdong region recorded the coseismic response wave or water shock wave. This paper analyzes the manifestation and characteristics of the coseismic wave of the observation data of ground deformation and underground fluid. From the record curves of each instrument,it can be seen that the normal observation form before the earthquake can be quickly restored after the co-seismic response,which proves the stability and reliability of the operation of geophysical observation equipment in the province. Through the analysis of the seismic response and recording ability of each observation instrument,it is expected to be helpful to further study the influence of these two earthquakes on the future seismic trend in Guangdong Province.
