Heterogeneous electrical structure of Kozu-shima volcanic island, Japan
Nearly twenty anomalous geoelectric field changes were observed before earthquakes at Kozu-shima Island, Japan, from 1997 to 2000. In order to help locating the current sources of the observed anomalous changes, a bipole-dipole resistivity survey was conducted. From the resistivity survey, including current injection into the ground, it was found that various features of the anomalous changes w...
متن کاملSubterranean electrical structure of Kozu-shima volcanic island, Japan
Following the electric current injection experiment carried out in 2009, a VLF-MT (Very Low Frequency Magnetotelluric) survey has been conducted in Kozu-shima Island to obtain further information on the subterranean electrical structure that might help understanding the results of our monitoring of geoelectric potentials. A number of VAN-type pre-seismic geoelectric potential anomalies were obs...
متن کاملPreseismic anomalous telluric current signals observed in Kozu-shima Island, Japan.
Monitoring of telluric current, which is practically a synonym for geoelectric potential difference, was conducted on Kozu-shima Island about 170 km south of Tokyo from May 14, 1997 to June 25, 2000. During the monitoring period, 19 anomalous telluric current changes (ATCs) were observed. Their possible correlation with nearby earthquakes was statistically examined by assuming various lead time...
متن کاملCharacterization of Early Microbial Communities on Volcanic Deposits along a Vegetation Gradient on the Island of Miyake, Japan
The 2000 eruption of Mount Oyama on the island of Miyake (Miyake-jima) created a unique opportunity to study the early ecosystem development on newly exposed terrestrial substrates. In this study, bacterial and fungal communities on 9- and 11-year-old volcanic deposits at poorly to fully vegetation-recovered sites in Miyake-jima, Japan, were characterized by conventional culture-based methods a...
متن کامل4.2 Nonrecursive Structure for Tomlinson-hara- Shima Precoding
Figure 12. Nonrecursive structure of Tomlinson–Harashima pre-coding for DC-free channels. to the ideal structure is negligible. In spite of the recur-sive structure, in each case, the precoder remains stable. The overflow handling of two's complement representation results in the desired periodical extension of the signal set at the decoder input. The additional noise at the decision point due ...
