Chubu University has established ULF/ELF electromagnetic observation network in order to study seismo-electromagnetics. We estimate the direction angle of the ULF emissions observed at three observation stations (Nakatsugawa, Shinojima and Minami Izu) before the 2007 Noto Hantou and 2008 Iwate-Miyagi Nairiku earthquakes. As a result of analysis, we found that observed ULF emissions have been propagated possibly from the direction of the epicenter of the 2007 Noto Hantou earthquake and the 2008 Iwate-Miyagi Nairiku earthquake. However, the observed ULF emissions possibly propagated from the epicentral region were not so convincing enough, and so we need more event studies.
