自２０世纪８０年代以来，在我国地震地下水动态观测网中陆续发现井水位在超远距离强震前的异常现象。这种异常表现为井水位的振荡与阶变，多出现在震前几小时至几天内，有一定的重现性。对这种异常的形成机制有多种不同观点，其中具有代表性的有强震的前驱波作用观点与强震孕育的大构造牵动观点等。该文作者从岩石圈与大气圈相互作用的角度新近提出了大气动力作用观点。尿管其异常机制尚不清楚，但这是非常值得注意的新现象，需要进行系统研究，以便不断完善地震预报科学探索的思路。
Since the 1980s, anomalous phenomena of well water level before long-range strong earthquakes have been found in the dynamic groundwater observation network of China. This anomaly is manifested as the oscillation and step change of the well water level, which occurs more often within a few hours to a few days before the earthquake, with a certain degree of reproducibility. There are many different viewpoints on the formation mechanism of this anomaly, among which there are representative views of the action of precursors of strong earthquakes and those of large structures that are nurtured by strong earthquakes. The author recently proposed the viewpoint of aerodynamic action from the perspective of the interaction between lithosphere and atmosphere. The abnormal mechanism of urinary catheter is not yet clear, but this is a new phenomenon worth noting. It needs systematic research in order to constantly improve the scientific exploration of earthquake prediction.
