| Research Abstract |
We developed and verified the high-sensitive andhigh-thunder-proof sensor measuring the ELF band magnetic field. We showed that thesferics measured by us were modulated by the earthquake. We proposed the method of detecting anomaly from the daily variation pattern using Hidden Markov Model(HMM), and showed validity. We proposed the signal separation method based on quasi-Ll norm, and showed validity. We showed that weak but anomalous electromagnetic radiations were able to detect by focusing on the azimuthal standard deviation.
