(Received There has been an enormous progress in the field of seismo-electromagnetics ( e.g.,  ), and it is a general consensus that electromagnetic effects not only in. Short-term (timescale of hours, days and weeks) earthquake (EQ) prediction is of essential importance to mitigate EQ disasters.
A triangle indicates the installation of an induction magnetometer and a circle, the torsion-type magnetometer. Different azimuthal directions in Fig. Analysis method of ULF magnetic field variations In addition to the installation of highly sensitive ULF sensors, we have to carry out sophisticated signal processing in order to detect and identify weak seismogenic ULF emissions.

Japan, Special Issue, July. The polarization value is found to remain at this value for a while. The time goes from a to e ; a 4 months before the swarm, b two months before the swarm, c 12 days before the swarm, d during the swarm and e two years after the swarm.
Future direction on a network of magnetic field observation three components In Japan some institutes magnetic observatories belonging to JMA, Institute of Geological Survey, etc.
The full line refers to Tarumizu. Ismaguilov V. When the radio emission is generated at the source region, it should be wide-banded.

The Loma Prieta earthquake happened very close to the observing station, so that it is better for us to indicate the results for this earthquake.
