In order to verify and clarify the ULF seismo-magnetic phenomena, a statistical investigation of the relation between magnetic anomalies and local seismicity has been performed. Geomagnetic data observed during 2001∼2010 at the Kakioka observation (JMA), Izu and Boso stations have been analyzed. Energy of ULF geomagnetic signals at the frequency around 0.01Hz has been investigated by wavelet transform...
Recently electromagnetic phenomena have been considered as a promising candidate for short-term earthquake prediction. In this study, we have investigated ULF (Ultra Low Frequency) electromagnetic phenomena possibly associated with underground activities in Izu and Boso Peninsula, Japan during 2000–2010. Daily average energy of geomagnetic signals at the frequency around 100Hz has been examined, and...
In this paper, five models are established by changing the location of the Shear Wall linked with the Ground, then analysis the Impact on the period and lateral displacement between floors when the Shear Wall linked with the Ground is Symmetrical layout and Asymmetrical layout. The results can serve a reference for the engineering.
