Abstract (in Japanese) (See Japanese page) 
(in English) It is know that the electromagnetic (EM) wave radiated from the earth's crust is observed before the great earthquake. The EM wave recorded in extremely low frequency band includes important information to understand the precursor phenomena of great earthquakes. The conventional research proposed EM wave classifier which does not require the training data of anomalous EM wave. However, the time resolution of anomalous EM wave detection is not enough. In this paper, we propose the anomalous detection of based on Autoencoder using an EM wave data to achieve a high time resolution detection.
