(emphasis mine DS)Phil Smith's 'The Earthquake' wrote:... I still couldn't figure out how a road that had been perfectly okay yesterday could have been so badly damaged by this morning. As I stood there wondering about this, there was a very deep and dreadful roaring sound which came from beneath my feet and the ground started to rock and shiver just as it had during Saturday night's earthquake. This was accompanied by flashes like lightning from the broken ground where the road had collapsed. To this day I am still not sure about this ... was my mind playing some sort of tricks on me to get me out of there, or did these flashes really happen? As rocks and stones started to tumble down the mountainside and land all around me, I leapt back on the Triumph, spun it around, and headed off flat-out down the hill to get clear of the mountain. Later that day, when scientists arrived to invesigate the earthquakes, I learned that there had indeed been two periods of aftershock activity recorded that morning and the first of these must have caused my "moving humps" which I saw near Boolara and the landslide which had taken the foundations out from underneath the road where I had had my roller coaster ride, and the second had caused the dreadful noise and rockfall which occurred while I was standing looking at the damage caused by the first one. ...

Also the telluric current-thread is applicable
I think I had also mentioned some anecdotal case of dunes spewing coronal discharges (basically lightning or streamers) out their tops?

That was in the waterspout-thread for sure, I remember that. It was mentioned the second time by me
at the end in that thread when (forgot his name) gave a nicely written article showing the kinetic and electromagnetic factors involved in the formation of tornado's.
Are you reviving that thread?
Sparks stood straight up from the tops of gypsum sand dunes in White Sands National Monument, New Mexico, as a thunderstorm passed overhead. Their properties were measured by instruments set up in 1971 by A. K. Kamra, who found that friction of the wind and blowing sand generated astonishingly high static voltages.

The dunes at White Sands National Monument in New Mexico are between 10 and 60 feet high. They are formed and re-formed by wind. Friction of the windblown gypsum sand creates static electricity.
