Lightning danger at a distance by hotspots. (see image) The hotspots are supposed to be negative charged and dangerous Dark Matter particles like Higgs particles. (see Q-FFF Theory)
Contact events with the hotspots are showing people with sometimes burning injuries in nature.The lightning itself is supposed to be deadly. How to protect? An earthed faraday cage. See on Ship bridges in the field etcetra
This "lightning sand" is digged out the sand showing molten sand channels around decaying and splitting hotspots or string knot particles (also higgs)
This molten sand is showing that the lightning stroke came from above deep into the ground and the smaller channels seem to be the result of decaying falling dark matter hotspots as shown in the former picture.
Only a part of the hotspot created sands are shown because these hotspots fell right from above the lightning stroke and merged with the main channel .
The LOGIC explanation of the angle between the large- and the smaller channels.
