Half a world away,
meanwhile, the earthquake may have been making an impact on the ionosphere. Newsline reports that hams operating the
North American "Noontime Net" on 40 meters noted "an attenuation
of the amateur bands" at nearly the exact time that the quake occurred. It
says researchers are studying possible links between earthquakes and
propagation, noting that stresses in rocks along a fault line just before a
quake cause the release of positive ions into the atmosphere. Those ions then
rise into the upper atmosphere, says the report, possibly causing anomalies in
the ionosphere.
