Aside from the obvious (snow build up) there were a combination of events.
the weather conditions and tempratures at the time (huge amount of snow deposits) and the previous months historical weather conditions and tempratures (melting freezing and fresh snow) causing a layer of unstable ice particles deep below the snow.
The question should be what were the causes of so many deaths.
Again there were a combination of events.
1. building of properties within the restricted areas of known avalanche risk
2. the avalanche committee ignoring the meteorological advisor's advice to evacuate the valley prior to the disaster, and by default trapping thousands of locals and tourists in the danger area to the point of rationing of food being enforced during the ensuing period.
3. tourist were still entering the valley when the warning had already been issued
4. whilst avalanches were happening daily in areas surrounding the village nobody considered the danger building directly above the village where no avalanches were occurring until it was too late.
Having said all that many were very fortunate, as the area that was devasted was relatively empty of people due to the town council holding an entertainment event in the centre to maintain moral, some that lost their lives had unfortunatly left the event early and were exposed to the full force of the avalanche.
Galtur has since had defence walls built with an integrated avalanche centre dedicated to the research of the cause and effect of the avalanche.
It has to be said Galtur is such a wonderful village, with the most welcoming of local people and well worth a visit any time of year.
It killed 31 people
Many who were missing were presumed dead
Of the 31, three children, a dog's owner, and a pregnant woman.
Galtür Avalanche happened on 1999-##-23.
As long as there is a deep slope, and avalanche can occur.
When there's snow at a right angle a avalanche can occur
They both occur on slanted landforms, occur suddenly and unexpectedly, use gravity, are caused by large amounts of unstable mass, and are capable of massive destruction.
The avalanche danger increases with major snowstorms and periods of thaw. More than 80 percent of these occur during or just after large snowstorms. The most avalanche-prone months are, in order, February, March, and January. Avalanches caused by thaw occur most often in April.
On Mountains :P . Nahh umm . France Switzerland Austria Etc .. they are normally european
well it occured on february /23/ 1999
Galtur, austria 1999 or something. it kills 31 people including something like 25 tourists. formed when an enormous snow pack collapses.

when you were born the mountains couldnt cope and made avalanche
winter time
An avalanche (snow or rocks) can occur in any mountainous area.
As long as there is a deep slope, and avalanche can occur.
A landslide is something that would occur in a dry climate ( a cliff side, dirt) and a avalanche occurs in the snow.
When there's snow at a right angle a avalanche can occur
Because BC and Alberta have mountains.
errr, there was more than 1 alavanche in 2009
Usually around winter because it snows.(Not always but you get what I mean??) And they occur where there are mountains.
