An avalanche is a rapid descent of snow, ice, and debris down a slope, influenced by factors such as slope angle and snowpack conditions. The 1970 Huascarán Avalanche, triggered by an earthquake, resulted in over 20,000 fatalities, highlighting the severe risks of avalanches. Understanding the causes and dynamics of avalanches is essential for predicting and managing their impact in mountainous regions.

Avalanches

Iskander, Karam, Mustafa,


Ahmed
An Avalanche is basically when a mass of material, which

So What Are They? is typically snow, moves very fast down a slope.

An avalanche is a mass of snow, ice, and debris that rapidly


descends a mountain. Factors influencing avalanches
include slope angle, snowpack conditions, and weather
patterns. Understanding these elements is crucial for
predicting and managing avalanche risks
What Are Causes Of
Avalanches?
Snow avalanches occur mostly after a snowstorm when a
fresh pile of snow is added onto the extra layer of the
snowpack. These new snow layers can keep increasing
but to an extent, due to the added force being pushed onto
the snowpack, this causes the snowpack to become
overloaded and become weak causing it to break away
from the mountain and pulling all the layers on top of it
down the slope.
Nevados Huascarán
Avalanche
The Huascarán Avalanche of 1970 was one of the
deadliest in history,It triggered by an earthquake. It
resulted in over 20,000 fatalities and widespread
destruction. This event highlights the potential
consequences of avalanches in mountainous regions.
Huascarán is the highest peak in Peru, and its avalanches
pose significant risks. This presentation analyzes the
impacts, causes, and mitigation strategies related to the
Huascarán Avalanche, aiming to enhance understanding
and preparedness for such natural disasters.
How Does It Start?

So basically, when a whole bunch of movement is made


like vibrant shaking, loud noises and rapid changes in
terrain. A huge mass of usually snow, stacks up and starts
to fall down the hill or mountain. This snow keeps
stacking up in mass and speed eventually hitting the end
of the mountain causing a huge pile of heavy snow to lay
on the surface.
In More Detail

When the snow breaks away from the slope, the snow
picks up speed as it’s sliding down and produce this
“river” of snow with icy particles and the moving mass
picks up more snow on the way and therefore it turns
bigger! It can travel faster than 320 km/h
