Περίληψη:
Electric and magnetic pulses are measured shortly (some minutes) before
earthquakes. These pulses differ greatly from the seismic electric
signals, which have appreciably longer lead times (days to months). In
the case of 1995 Grevena-Kozani earthquake with a magnitude of 6.8, the
time difference of approximate to 1 s was observed between the
recordings of the electric and magnetic components at Ioannina station,
providing further support that the pulses were not from local man-made
source but most probably from the epicentral area about 100 km away. A
tentative explanation of the phenomenon is proposed considering what
happens in the very last stage before the earthquake occurrence. (c)
