| Zusammenfassung |
| Numerous electromagnetic changes possibly related with earthquakes have been
independently reported and have even been attempted to apply to short-term
prediction of earthquakes. However, there are active debates on the above
issue because the seismogenic process is rather complicated and the
studies have been mainly empirical (i.e. a kind of experience-based approach). Thus,
a physics-based study would be helpful for understanding earthquake-related
electromagnetic phenomena and strengthening their applications. As a
potential physics-based approach, I present an integrated research scheme,
taking into account the interaction among observation, methodology, and
physical model. For simplicity, this work focuses only on the
earthquake-related DC-ULF electromagnetic phenomena. The main approach
includes the following key problems: (1) how to perform a reliable and
appropriate observation with some clear physical quantities; (2) how to
develop a robust methodology to reveal weak earthquake-related
electromagnetic signals from noisy background; and (3) how to develop plausible
physical models based on theoretical analyses and/or laboratory experiments
for the explanation of the earthquake-related electromagnetic signals
observed in the field conditions. |
