Physics-based Study on Electromagnetic Phenomena Possibly Associated with Earthquakes

Although numerous observing electromagnetic data at a broad range of frequencies seem to prove the existence of the electromagnetic phenomena associated with earthquakes, the above phenomena cannot be fully understood at the current stage, due to the complexity of seismogenic process and inhomogeneity of underground resistivity structure. Thus, it would be important to make some physics-based study to strengthen the understanding of earthquake-related electromagnetic phenomena. One basic idea is to work in an integrated scheme considering the interaction among observation, methodology and physical model. Because reliable data are the basis for the study on earthquake-related electromagnetic phenomena, first, a reliable and appropriate observation is required. Another important issue is how to reveal earthquake-related electromagnetic signals from background noise, which requires further study on methodology. Of course, some reliability and statistic analyses of the above phenomena may be required to ensure any convincing conclusion. Besides, it is important to perform some theoretical analyses and laboratory experiments for the physical model study on the earthquake-related electromagnetic phenomena. We will report the preliminary results based on the above integrated research scheme of the study on earthquake-related electromagnetic phenomena.
