Avalanches

An avalanche is a mass of snow moving rapidly down a slope, sometimes reaching speeds of 80 miles per hour, triggered by either natural causes or human activity. Avalanches are responsible for more deaths per year than earthquakes. They are often triggered the first clear day after a storm because it has made the snowpack unstable. This category includes descriptions of avalanches and how they occur, their effects, warning signs, and safety measures.

How many avalanches are caused by skiers?

It is estimated that around 90% of avalanches are triggered by people, with skiers and snowmobilers being the primary contributors. Skiers account for a significant portion of avalanche accidents due to their presence in high-risk backcountry areas.

What are the long term effects of placental abruption on the mother?

I have had two boys via emergency caesarian due to placental abruption. For my first child, both of us were very lucky to survive, he was in special care baby unit for three weeks and i had to have blood transfusions, my uterus did not contract properly after delivery and my blood was not clotting. I had a priest come to see me and also wanted to see my son. It was very scary and the thought of me losing my son was unbearable. I have blocked out most of that time and tend to focus on the future. I also had a second child and was high risk. I had a caesarian planned for 5th may as i was high risk but went into labour on 2nd may. In third stages of labour i suffered a placental abruption but this time round i knew what was happening and my boy was in distress. Everything came flooding back and i was hysterical as i didnt want to lose him. Luckily after emergency caesarian he was okay no stay in the special care baby unit but i was borderline for a blood transfusion and they decided against it. This resulted in me being severely anaemic and very ill for a week or so after the birth.

The long term effects are really mental rather than physical. I have since found out that i have an iron deficiency which contributed to why this happened to me. I stay focused on the future and not on the past and count my blessings that both of my boys and me survived as there are so many cases where this doesnt happen. Neither of my childbirths hold pleasant memories but the memories we have built thereafter are brilliant ones and i wouldn't wish it any other way.

Why do patrols deliberately cause avalanches?

Patrols trigger controlled avalanches to mitigate the risk of spontaneous avalanches in high-risk areas. By intentionally setting off smaller avalanches, they can reduce the buildup of unstable snowpack and protect skiers and other mountain users from unexpected avalanches. It's a proactive measure to improve safety in avalanche-prone regions.

How often do avalanches occur?

Avalanches can occur throughout the year, but they are most common during the winter and spring months when there is more snow accumulation. The frequency of avalanches can vary depending on factors such as snow conditions, terrain, and weather patterns. It is important to be aware of avalanche risk and take appropriate precautions when traveling in avalanche-prone areas.

What effects on nature do Avalanches have?

Avalanches have minor affects compared to many other natural disasters. Most avalanches kill trees, and destroy plants in their path. It is possible that an unlucky animal or two could be killed.

Jacob is cool Jeremy isn,t

^i don't agree with that answer. Avalanches take away ice, rocks, trees, and homes away from a habitat greatly effecting people and animals there. and FYI i bet it kills way more then "an unlucky animal or two"

Environmental Impact

Effects of this Avalanches caused people to be buried alive leaving people dead or criticly injured. Power and water supplies got cut off. It closes ski trails and damages properties it also destroyes forests so animals no longer have a homes

How did the Galtur Avalanche occur?

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.

What is supposed to happen from a spiritual standpoint in 2019?

From a spiritual standpoint, 2019 may be a time of personal growth, transformation, and awakening. It could bring opportunities for increased self-awareness, healing, and connection with higher consciousness. It is a year to listen to your intuition, release old patterns, and align with your true purpose.

How can people decrease the damage that avalanches do?

the way that people in an avalanche disaster area decrease the damage done by a avalanche is they put up snow fences that are like fences that stand on an angle and they are meant to break and roll with the snow and while the snow is rolling, it's very likely for the snow fences to stick back into the ground and that decreases the avalanches speed so that when it hits it isn't as bad

Is the 2008 lug pattern the same as 2005 on a avalanche?

Yes, the lug pattern for a 2005 and 2008 Chevrolet Avalanche is the same, which is 6x139.7. This means both model years have the same number of lugs (6) and the same distance between the lugs (139.7 mm).

How do avalanches form?

Avalanches form when a layer of snow collapses and slides downhill. This can happen due to factors such as a weak layer of snowpack, steep slopes, and triggers like human activity or natural events. The sliding snow collects more snow as it moves, creating a fast-moving and potentially dangerous avalanche.

How many deaths a year are attributed to unsafe water sanitation and hygiene?

Water-related diseases are the most common cause of illness and death among the poor of developing countries. According to the World Health Organization, 1.6 million deaths per year can be attributed to unsafe water, poor sanitation and insufficient hygiene. (2005 UN Millennium Project)

Avalanches where happen?

Avalanches can happen in mountainous regions where there is a build-up of snow on a steep slope. Factors such as temperature changes, snowpack stability, and additional precipitation can trigger an avalanche. Human activities like skiing, snowmobiling, and snowboarding can also trigger avalanches.

Where do avalanches occur?

Avalanches occur in the back country where we like to play. Most avalanches occur on slopes between 35 & 45 degrees. Slopes less than 30 degrees rarely produce avalanches, and slopes greater than about 50 degrees tend to sluff off the snow often, and not build up slabs, not to say they will never avalanche down. Stay alert, always pay attention to your surroundings

How do you prevent avalanches?

To prevent avalanches, measures such as controlled detonations to trigger small avalanches before they become dangerous, installing snow fences and barriers to redirect snow accumulation, and monitoring snowpack conditions to forecast avalanche risk and issue appropriate warnings are common practices. Additionally, avoiding high-risk areas during times of elevated avalanche danger and undergoing proper training in avalanche safety can help prevent accidents.

How does an avalanche occur?

An avalanche occurs when a mass of snow falls down a mountainside. That is because new snow (which is not wet) accumulates on a more heavy snow layer. Since the new snow layer is not compact, it could slide down toward the base of the mountain. Avalanches could be triggered by loud noise (yells, firearm shots, etc.). Skiers, snowboarders and climbers could also cause an avalanche. There are two ways to reduce avalanche risks: by installing snowsheds or by triggering controlled avalanches. These protection fences are made of rocks, soil and other materials. They prevent avalanches to fill trails used by humans. Controlled avalanches cause the accumulated snow to fall down before it could trigger avalanches by itself. When nobody is in danger, explosives are used to produce a loud noise that causes an avalanche. Avalanches could be seen every winter in mountainous regions of Québec. Fortunately, they do not often occur near inhabited areas. During the winter, do not venture in the mountain without an adult. If you walk in a trail after a snow fall, do not walk in the middle of it, but rather on the side. Avalanches always fall down in the middle of the path; thus, if you are on the side, the risks of being hit by the avalanche are lower. * In 1999, an avalanche killed many people in Kangiqsualujjuaq, near the Ungava Bay in northern Québec.
The avalanches occur as a result of the snow packed mountains become to heavy to support itself and therefore fall at the base of the mountain.

What were the long-term effects on families after World War 1?

You'd need to look in a few books to get a good answer to this question. Also what would we consider long term? 50-60 years in history is the blink of an eye. Maybe the 'lasting effects' of World War II. One could be the continuing, but so far relatively brief, role of the U.S. as a superpower and global cop. It has been said that WWI was and industrial war. WWII was a continuation of that WWI in that it was a war for resources. Cold war again an extension became a war for markets. Current situation could possibly be for energy? Religion? Income and Resource disparity?

What time of day or year are avalanches most likely to happen?

This is an educated guess only: The most likely time of day for an avalanche would be in the afternoon and the most likely time of year would be in the spring. The logic behind this "guess" is that as the temperature begins to rise (i.e., in the afternoons and in the spring), the snow begins to melt resulting in the weight of the snowpack becoming heavier until reaching the point where the underlying snow is no longer able to support it and lets loose. This is assuming there is no external triggering event such as an earthquake.

What are the environmental causes of an avalanche?

Environmental causes of avalanches include heavy snowfall, unstable snowpack due to temperature changes, rapid warming, or rain on snow, and steep slopes that can trigger snow to slide downhill. Other factors can include terrain features such as cliffs or gullies that can channel snow into slides.

Would 26 inch rims mess up tha transmission on a 07 avalanche?

It is possible that 26 inch rims could put additional strain on the transmission of a 2007 Avalanche. The larger rims and tires can increase the overall weight and size of the wheels, which can impact the transmission's ability to handle the load. It is recommended to consult with a mechanic or automotive expert to determine the compatibility and potential impacts before making any modifications.

How are avalanches caused?

Avalanches are caused when a big impact of noise strikes. This is because sound vibrates objects and therefore vibrates mounds of snow, causing them to tumble down.

How do avalanches change an environment?

An avalanche can affect the man made environment by crushing villages, homes, and buildings.
