The ultra-low-frequency （ULF） electromagnetic emission is recently recognized as one of the most promising candidates for short-term earthquake （EQ） prediction. This paper reviews previous convincing evidence on the presence of ULF emissions before three major EQs. Then, we present further statistical study on the ULF occurrence, our networks of ULF monitoring in different spatial scales in Japan and finally we present several signal processings to identify the seismogenic emissions by showing latest results for recent large EQs.

＜正＞ The purpose of this report is to find out any ULF signature for the earthquakes in Izu islands in July 2000 （associated with volcanic activity） by means of a new signal processing method. The ULF data observed at closely-spaced three stations in Izu peninsula, are subjected to the principal component analysis （PCA）, and we have found that this PCA is very effective in distinguishing among different sources of ULF emissions （geomagnetic variation, man-made noise, and seismogenic emission）. While, the first and second principal components are found to be associated with geomagnetic variation and man-made activity, respectively, the third principal component （residual noise like seismogenic emission if it exists） at night has indicated a significant temporal evolution;an enhancement for about 1.5 months （from early May to middle June） and a conspicuous minimum about ten days before the first earthquake on July 1 （magnitude 6.4）, followed by a sharp increase a few days before the quakes. Furthermore, this component is found to be back to the background level a few months later than the quakes. This temporal pattern is in good agreement with those for previous large earthquake （Spitak, Loma Prieta, Guam and Biak earthquakes）, so that this temporal evolution for the third principal component found by PCA is likely to be a precursory ULF signature of those Izu islands earthquakes with its intensity of the order of 5% of the first principal component.

＜正＞Many previous investigations suggested that the ultra-low-frequency （ULF, up to 30Hz） is a prospective band for the search for earthquake precursory signatures （hattori, et al., 2013）. Some study also indicated that the diurnal magnetic variations may be disturbed by large earthquakes （Duma et al., 2003）. In this study,

＜正＞Landslide is one of the severe disasters triggered by rainfalls and earthquakes. In this study, we pay an attention to the rainfall-induced landslide. So far, we are trying to develop the early warning system for the landslide using passive electromagnetic approach, that is self-potential （SP） measurement. Previous our indoor experiments provide some important facts for landslide preparation process in hydrological, geotechnical, and
