| Abstract(in English) | It is known that the detection of an anomalous signal radiated from the earth's crust is useful for predicting the precursor of the earthquakes. We observed the electromagnetic (EM) wave using the Extremely Low Frequency band. Various methods for detection of an anomalous signal have been proposed. Those methods have some problems. In this paper, we propose the anomalous signal detection based on HMM using the amplitude density distribution of an EM wave, which does not contain an anomalous signal. The input signals are calculated from the observed EM wave. An amplitude density distribution calculated from the image of an EM wave is employed as the input of HMM. The optimal input configuration of image to calculate amplitude density distribution for the detection of anomalous signal and the number of states of HMM are examined. |
