Do you remember reading "Ionospheric Ducting at HF" by V. Kanevsky, UL7GW, in
Sept. 1979 QST magazine? He makes the case that fault lines affect the
ionoshpere over heard, resulting in ducting or enhanced propagation for those
near the fault. I would imagine a major event like the one that just happenened
in Japan would have a coresponding effect on the ionosphere as well. I remember
when I read this artcile thinking that Minnesota is 1500 miles from the edge of
any tectonic plate....another reason propagation stinks here.
