NZ's quake last night created a phenomenon where, as the plates move, the Earth's positive electric field is disrupted by the enormous force. The rock actually produces a separation charge creating a 'dent' in the electric field and causing the atmospheric discharge.
It's been called ( Positive Hole) p-hole charge clouds, which arrive at the
Earth’s surface, generate a positive ground potential. The discovery of p-holes as powerful charge carriers that are activated through high levels of stress in the Earth’s crust before earthquakes may also provide an answer to ionospheric perturbations. If p-hole charge clouds spread to the surface, they not only generate high electric fields at the rock-to-air interface
but also lead to an overall increase in the ground potential.
If the Earth’s ground reaches sufficiently high positive values, we have a situation that can be described as a capacitor. The Earth’s surface represents one fixed capacitor plate.
The lower edge of the highly conductive ionosphere represents the opposite capacitor plate, which can move up or down or to the side. If the positive ground potential increases due to the arrival of p-hole charge clouds, the associated electric field is bound to affect the ionospheric capacitor plate.
