地下流体的响应能比较直观地反映地下断层深部流体的变化。2025年3月28日缅甸发生MS7.9地震,云南井网水位、水温不同形态出现同震异常响应,水位振荡形态主要表现为阶变型和水震波振荡型两种形态,水温主要表现为阶变型。从同震响应的分布、时间、幅度等分析各水位、水温的响应特征。研究这次水位、水温同震响应有助于更深认识地震和流体之间的相互作用,对以后中强地震的发生具有一定的指示意义。
The response of subsurface fluids can more intuitively reflect changes in deep-seated fluids along under⁃ground faults. On March 28, 2025, an MS7.9 earthquake occurred in Myanmar, triggering co-seismic anomalous re⁃sponses in various forms of water level and water temperature within the Yunnan well network. The water level oscil⁃lations primarily manifested as step-like changes and seismic wave oscillations, while the water temperature mainly exhibited step-like variations. This paper analyzes the response characteristics of water level and water temperature in terms of distribution, timing, patterns, and amplitude of the co-seismic responses. Studying these co-seismic re⁃sponses of water level and water temperature contributes to a deeper understanding of the interaction between earth⁃quakes and fluids, providing certain indicative significance for the occurrence of moderate to strong earthquakes in the future.
