Detection of anomalous environmental electromagnetic waves based on daily average using Hidden Markov Model

Japan is one of the countries where a lot of earthquakes occur. Therefore it is very important to catch the portent of earthquakes. Anomalous environmental electromagnetic (EM) radiation waves have been reported as the portent of earthquakes. Therefore in order to detect the anomalous EM waves we propose a method for detecting anomalous EM waves based on its daily average using HMM. Experimental results for huge earthquakes show the effectiveness of the proposed method.
