| Zusammenfassung |
| There have been many reports on ULF electromagnetic phenomena associated with
the 2000 Izu Islands earthquake swarm. In this study, seismo-magnetic
anomalies are presented by examining energy variations of signatures at the
periods around 100 s. Geomagnetic data observed at three stations in Izu
Peninsula from 1 January 2000 to 30 April 2001 have been analyzed and wavelet
transform has been performed. In order to indentify anomalous changes from
ionosphere disturbances, Kakioka station has been chosen as a reference
station, and the similar data analysis has been performed. The results
suggest that the unusual energy enhancement of the Z component, which only
appears in Izu Peninsula from late June until early November 2000, might
possibly be one of electromagnetic phenomena associated with the 2000 Izu
Islands earthquake swarm. |
