Question

Couldn't they use heat sensers to detect people in avalanches?

Answer 1

Maybe if they weren't buried very deep, but the snow would quickly cancel out the heat given off by the person.

Answer 2

yeah, but they don't because they are stupid!

Answer 3

Let's think about this. There's  a layer of "relatively cold" snow on top.

Answer 4

The Inuit build igloos to get out of the weather because ice is fairly good thermal insulation. Snow being ice with air mixed in is an even better insulator.

Answer 5

The best thing they use are dogs. I have a SAR dog and he's pretty good. However, it's not perfect. It works best when someone was there to point in the general direction of where the person was originally. Then we know, by the velocity of the avalanche, about how far he would have been taken. At that point we have as many dogs as we can on the site, as quickly as we can.

Many people are found after an avalanche, but it's mother nature, and you know what they say... don't f@#$ with Mother Nature.

Answer 6

It can't penetrate that deeply, and being covered in snow would give you hypothermia, so you wouldn't appear "warm" anyway.

Answer 7

no because the snow would turn your body tempeture really low so that its basically the same (maybe a little higher) than the snow

Answer 8

Because they would work on infrared, they would only be able to measure surface heat - i.e. cold.

Answer 9

That makes nooo sense.

Answer 10

i don't think so

Answer 11

no. its flippin cold everywhere, heat sensors don't go deep enough. people usually get barried ten to twenty feet below. good thought tho.

Answer 12

depends how deep the person is or how long the person has been covered and how sensitive the heat camera is

Answer 13

More than likely yes...unless they were dead. Then there would be no heat in there bodies to detect. Also if the snow and ice was very thick it probably could not detect anyone.

Answer 14

well first of all some idiots out here think our body temp. changes when were not dead well it doesn't it stays between 95 degrees and 98.6 degrees all the time because were warm blood and unless she said amphibians in an avalanch then they could possibly if they were burried above 8 ft then the sensor would be strong enough but barley so sometimes is the answer

Answer 15

How GOOD do you think heat sensors are? If you are buried underneath a lot of snow you think the heat sensor can sense through like 10 feet of snow?

Heat sensors usually detect SURFACE heat.

Answer 16

Yea, she is right, you couldn't, maybe as soon as they were covered in the snow, but their body tempurture would drop pretty fast.

Answer 17

I dont believe that it would be very warm under feet of snow. i am sure by the time a rescue took place whomever was warm would be frozen,

Answer 18

i guess it would depend on how long your there

your body temperature would probably change fast

Answer 19

no bcoz its reli cold in the avalnche n they cant detect it lol coz i1 small human being tons of ice?
