What would be the path up through a human? Electricity needs to travel somewhere, from negative to positive, and the person/object on the ground is already at 'ground potential' (electrical term).

That is due to the muscles reflexing in such a way that they are propelled a huge distance. It brings up the question, how great is the potential of the human body when fully utilised ..so we're all grasshoppers. Link to comment Share on other sites More sharing options...

The tree is actually a pretty good target for the lightning to strike, tall and shortest path to ground and back. The article title saying lightning struck them is probably a bit in accurate. It struck near them me thinks. 7- Avoid being the tallest object around. If caught in an open field, get as low as you can but do not lie prone on the ground, this will expose your heart to the electrical current from the lightning bolt. Squat on the balls of your feet to have minimum contact with the ground. Place your hands over your ears and your head between your knees. Link to comment Share on other sites More sharing options...

Always find shelter indoors or in a non convertible car. Having said that, you never know what fate is going to throw at you. R.I.P. to the young lady, and a speedy recovery to the man. Never under a single tree but OK in a forest if your tree is smaller than others around you. Lightening normally strikes the highest point. Don't be the highest thing around.

However, true pine trees (Genus Pinus) do not have deep tap roots. There are very few true pines in Thailand - only in the Chiang Mai-Mae Hong Son area. These "pines" are almost certainly Casuarina equisetifolia, and are not conifers at all. Don't know about their tap roots. 1 Link to comment Share on other sites More sharing options...

Same logic as "people who were struck by lightning had a head, so they are more in danger than than those without" No there is some evidence that others have also been hit in similar circumstances....you sound like you work for the manufacturers and next will be denying a link to brain cancer!

simon43 Posted May 27, 2017 Share Posted May 27, 2017 (edited) As a shortwave radio amateur, I'm very much aware of the risks of lightning strikes on my wire and vertical antennas. I use a fast-acting commercial lightning strike unit in the feed-line to my transmitter which will conduct the current to ground in the event of a direct strike. As for being thrown a distance by muscle spasm, if hit by lightning or a large electric shock, I recall in the 70's when I used to build valve transmitters in my UK bedroom. These typically used a voltage of about 2,500 volts on the top cap of the transmitting valves. On one occasion during some live tests, I touched the top cap by accident and then woke up on the other side of my bedroom, having been flung right across the room by my muscle spasms, (or was it by a built-in desire for self-preservation?)

Dumbastheycome Posted May 27, 2017 Share Posted May 27, 2017 I am tempted to laugh. fact is that lightening " usually" contacts at highest point . Which implies that on a small percentage of cases it strikes at a point lower. Probably/possibly because that lower point is closer to the focal potential energy than another higher point. Proximity to the point of the strike is obviously important but equally obvious is that direct or near to the incredible energy discharge is potentially lethal. Science still has no full understanding of the various forms of lightening. It is now known sometimes it can emit x-ray emissions despite a non nuclear presence. (?) Ball lightening is a phenonomen that has intrigued people for eons. So the reality remains that in a lightening storm the safest place is under cover in a location least likely to be the point of strike. How you squat or hover will have little to stop you being a pork crisp in the very very unlikely case you receive a direct hit ! Link to comment Share on other sites More sharing options...

kangaloowest Posted May 28, 2017 Share Posted May 28, 2017 I do not think that is too far past the realms of Physics, for a super highly charged electrical current, to use a wireless/frequency to find earth. After all, wireless frequencies are a form of energy transmission, and therefore must be considered an electrical conductor. https://en.wikipedia.org/wiki/Wireless_power_transfer I believe that when there is such a highly charged current looking to earth, it will use whatever means necessary to get there, to whether it be a “good earth” or a “poor one”. I am not saying that using a mobile phone in an electrical storm is unsafe or otherwise, but I for one, certainly do not wish to test the boundaries of the Physics of Nature. In relation to this topic, a good mate of mine from Perth WA, who was a secondary teacher, travelled from Perth to Isaan, a few years back, with a group of students, and a teaching assistant, on a cross-cultural exchange exercise. When out with the group one day, a Thunderstorm hit the area, so they all madly scrambled for cover from the pelting rain under a large tree. There was a lightning strike that hit the ground not far from the sheltered group that travelled through the ground instantly killing my mate, and two Thai students, also badly injuring the teaching assistant, whom later died from injuries sustained. Everyone else in the group survived unscathed. Yes, the surrounding area was wet from the rain, as were the huddled group under the tree. No, the lightning did not strike the tree, but it did strike the wet ground nearby. Why were three people out of a group killed instantly, and one badly injured, later to pass away, and the rest left unharmed ??. Maybe there was a root of the tree not far from the ground surface that acted as a conducting rod, attracting the lighting as an earthing point, and these people were in the wrong place at the wrong time. I do not know anything more than the devastating facts that we were left with, but I do know one thing, that I will never consciously give the Physics of Nature a chance to harm me or others through mischance/ignorance or naivety.
