Absolutely, IMO. The characteristics of the discharges interacting with Earths surface, or below the surface, will be so diverse that many different effects could occur. The nature of the surface material will also result in different end results. We need to categorise the possible types of interaction, from gentle electric winds through to short pulse, extreme energy arc discharge, and link them to the appropriate surface features. There are so many surface features or objects lying around that can not be explained by conventional geological forces that we have to look at alternative processes for their formation, and what else other than electrical and magnetic forces could produce such oddities? That what are classified as igneous and metamorphic rock can be produced by EM forces is beyond a doubt, according to the engineers I have questioned, but the energy levels required, especialy for large scale structures, soon puts the nubers into the "unbelievable" range. And there's the rub. A conventional model relying on extreme time periods, heat and very high pressure, or electrical forces of mind numbing proportions.Is there a possibility that some of these are not from "space"? and have been produced in the intense cauldron of a mega-strike to ground? .. possibly a transmutaion scenario?
Anyway, with the Chelyabinsk object, it would seem that it should have hit the water with around 250 ft/sec velocity, and based on what I have been able to determine, the composition of the object means that it should have turned to small fragments within the top 5 feet of the water surface. It's a rather complex event to visualise, but I am extremely puzzled as to why none of the scientists or engineers I have contacted seem to even want to take a stab at a model of such an event.
@ nick c
Just my opinion of course, but I think a sun grazer would have acquired a charge such that the potential difference between the inside of such an object, and the rapid change of exterior charge level on approaching the Earth would result (in a rocky, not metallic meteor) in an exploding capacitor type event, shattering the object. The rain of hot pebbles or gravel described in historical events is from just such a process I'd think. The discharge to ground is what will produce the larger objects, through an EM lithification, recrystalisation, melting, etc, processes.Or, that it is a fragment of a former sun grazer comet.
