with terrifying speed an avalanche can
Rumble down a mountain slope burying
everything in his path under a lethal
blanket of snow each year about 150
people in Europe and North America die
from avalanches large ones can wipe out
for it and erase a mountain abilities
avalanches come in many forms some
called Slough consists of sliding loose
snow others called slab avalanches grow
in large sections of the snowpack crack
off and crash down the slope as snowfall
it builds up layer upon layer with
enough time the layers will harden and
bond to one another but when layers
formed we Claus any new snow falls on an
unstable foundation and waits for right
trigger avalanches are caused by sudden
changes a heavy snowfall strong winds or
a rapid change in temperature
the shape and angle of the slope are
important factors slopes over 60 degrees
are usually too steep slopes under 25
degrees if you general the danger zone
comes between 30 and 45 degrees just
where people like to ski and sled 90% of
avalanche victims died because they or
someone with them accidentally trigger
an avalanche contrary to popular opinion
loud noises like yelling won’t trigger
an avalanche in most cases it’s the
sudden weight of a skier or snowmobile
that makes the surface unstable then the
Avalanche descends had speeds up to 80
miles an hour as winter sports become
more popular avalanches pose more of a
threat ski patrols now monitor popular
slopes to prevent avalanches from ever
happening
cannons fire explosives as slam in the
snow bats to trigger small avalanches
before the build-up becomes a problem
search and rescue teams practice
locating and digging out people trapped
underneath the snow
but ultimately it’s up to every person
to watch out when they’re on the slope
so pay attention to the weather look for
warning signs learn what to do in an
emergency because everything can change
in just a few seconds
