| 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 have observed the electromagnetic (EM) wave using the Extremely Low Frequency band. Various methods for detection of an anomalous signal have been proposed. The known problem of those technique is related to a false detection due to the limitation of training data. We proposed the HMM based anomalous signal detection whose training data is the amplitude density distribution extracted from normal EM wave signals. However, the time resolution of anomalous signal detection is not discussed enough. In this paper, anomalous signal detection using amplitude density distribution calculated by short term signals is proposed to track a temporal change of acceptance probability. |
