content: The following article, seems to explain (from my quick glance at it) why four legged creatures, are more susceptible to lightning, because their legs are spread in such a way that the potential difference, unfortunately can kill them. Where as, two legged creatures, don't have that problem. So are usually safer when it comes to lightning.http://scienceblogs.com/tetrapodzoology/2009/07/15/mammal-deaths-by-lightning/

content: The problem is not the direct lightening strike but after the bolt raises the potential in one area, you then get a significant voltage gradient radiating out from the central impact spot. My old house , on the top of a modest hill, had very poorly conductive soil,(high rainfall tends to leach out salts ) so for the lightening rods/ earth mat we had to dig multiple very long trenches to try to get soil impedance/conductance nice and low.With a significant gradient e.g. tens of thousands of volts per meter, the wet cow/pig/deer is more conductive than the soil so guess where the current flows.One strike in our old house hit a tree, attached to it was a metal pipe that was buried for about 20m under the ground before arriving at the house. The strike hit the tree, blew off a branch or two, but there was not sufficient earth conductance between the pipe and the soil (the soil too insulative) the current came out across a desk - via the telephone line (no one there fortunately) finding a 'good earth' via the mains socket earth connected to the lightening rod system/earth mat (at the power box). The scorch marks and the smell were very telling.

content: The Norwegian wildlife representative said on the news that a serious heavy thunderstorm was passing by last Friday on this very location and it was after that they found them dead. And there is no high voltage power line at the location. If the flash strik'ed vertical and or spread out due to poor ground conductivity instead of straight down into one well conducting spot and knowing this location is close up among clouds and if this storm was low in altitude then one flash could have traveled through them all, perhaps! The wildlife representative also said all dead deer's was inside 60-80m diameter area.This article tells about two hunters that was only 3km away from the deers the same day and was surprised by the storm and felt the electricity in their spines as they rapidly had taken cover under a rock during flash strike overhead!http://www.vg.no/nyheter/innenriks/dyrene/323-reinsdyr-drept-av-lyn-paa-hardangervidda-ble-kvalm-av-aa-vaere-der/a/23778041/

content: Quote from: MT on August 29, 2016, 10:57:58 amIf you ever feel huge static electric fields and see hair standing up when in nature, "get the hell out of that place as fast as you can" is a preferable life saving option. American TV show about miners/gem collectors had a short scene on camera where hair of a person started to lift from static when on top of the rocky mountain. Immediate action was taken to get to safety.
