An interpretation is made of magnetic variations of the bay type observed in Iceland, in terms of the behavior of the Z/H ratio with distance from source. Observations from Greenland observatories are used to provide an estimate of the characteristic width of the auroral current system. It is concluded that a region of enhanced electrical conductivity must underlie Iceland. If the anomalous material has the conductivity of molten lava, its most probable depth is 30 km, and, on the basis of the available observations, it appears to underlie the entire island."

So the continents spread apart as the Earth widened at the equator and narrowed at the poles. That's why the crust is thinner under the oceans. Since the Earth continues slowly to expand or contract at the equator, vulcanism and earthquakes continue to occur, with some involvement of electrical forces.
Have you noticed that this December is unusually cold so far? Could the fact that we have had a record number of volcanoes erupt in 2013 be responsible? Certainly an unusually calm solar cycle is playing a significant role in producing all of this cold weather, but as you will see below the truth is that throughout human history volcanic eruptions have produced some of the coldest winters ever recorded.

I think this is one of the effects of earthquakes. Another is the release of gases from the Earth, specifically radon, that can be measured prior to the actual earthquake and could be used to assist in developing a warning system to alert residents of the affected areas. I'm also not sure that the electric currents come from the Earth exclusively; they could be coming from the atmosphere (something like a "leader") and the flashes occur when the connection is made with the grounding current.

The build-up of charge across compressed rocks can cause sudden electrical breakdown. So, earthquakes could be considered a form of underground lightning. If earthquakes are underground lightning bolts, then perhaps seismic waves are the thunderclaps.
Steve Smith wrote:In that case, it seems likely that the majority of energy released during an earthquake may not be from the fracturing and movement of strata, but the result of electrical energy released within the rock matrix.
