1989 solar flare, answer to Canie

Hello Canie-just talking to an office employee here who is interested in the Aurora and she saw it in 1989 from Santa Barbara. This was probably after the very large March 1989 flare. That flare was followed by 4 days by a M6.6 in Malawi (a country in African where I spent a month in 1985). Lowell and I discussed the series of earthquakes in the east Africa rift system that seemed to follow flares by 4 days or so. But, I have not seen much evidence of this the last few years. I'm someone who was once pretty convinced that Lowell was correct that flares and geomagnetic storms trigger earthquakes. But, in the last 2 years I have really lost confidence in this. I still think that a few random earthquakes may be triggered-for example the M5 Au Sable (?) Adirondacks earthquake was in the middle of a long duration storm, and a few in Canada in the last year also seemed to be during storms..... Concerning the asbtract-it is Mark Legg who invited me to give the talk. I ought to give him a call. I may talk about block motion in the Bay. I have a submitted paper to BSSA where we have block models that clockwise rotation of small blocks is absorbing the right-lateral slip on faults like the Palos Verdes so that they do not reach the edge of the Santa Monica Mts (do not reach the Santa Monica fault). I will mostly talk about fault geometry and kinematics, with various 3D views, including of earthquakes.......The discovery of most interest is that we mapped a blind fault beneath the Shelf Projection anticlinorium that we think is active-it may have a huge significance to hazard to L.A......Chris
