A.Was it easy or difficult to find your community’s plan? Describe how long it took, or in the extreme case, that you never actually found it online.
-Since I saw a few posts from Juneau already I decided to go with Lake County, Colorado (my last home). I googled Lake County, the first link was the website. And underneath the departments menu on the homepage they have a link with Emergency Management. It was all a matter of seconds really.
B.Describe one thing you think shows your community is well-prepared in case of a disaster
-I like the different ways that they have to send out emergency notifications, and information in general. The website appears to be updated, they have a Facebook page for the emergency management department, and they have a listing you can sign up for with email or phone number to receive constant notifications.
C.Describe one way you think an improvement could be made to your community’s plan.
-The biggest problem I have with the plan, the pdf is flipped the wrong way. They printed the book on landscape, but have it posted as portrait. If you want to read it with out printing it, you are going to have one heck of a crick in your neck.
D.Answer the following question: Do you feel better or worse about how well your community is prepared after reading its plan?
-I feel about the same, the community was always very open about its practicing for emergencies, and often times invited the community to seminars to teach them what to do in different situations. They are a community that relies on each other heavily due to being a good distance from other towns and counties.
While reading the IS-22 I realized that I am prepared for most situations unless I am at work! Although, we have some emergency supplies at work, it is not tailored to everyone, so it would be best if I could leave something there in case I had to evacuate while working. I chose to make a comic to illustrate that.
Waldo Canyon fire human impacts
Yungay, Peru avalanche 1970
The article that I liked the most for the Waldo Canyon fire was the CNN article. The article was released before the fire was fully contained. It has photographs of the destruction, and of the people being influenced by it. The article covers the impacts brought on by the fire and by the evil nature of some people and just how it effected those involved.
Articles were a little harder to come by for the avalanche case study however. Granted Wikipedia is not always the most trust worthy of sites but, it did let in some insight of how restrictive the government of Peru is and how they could have avoided the mass deaths from the avalanche if they released the information and took action when it came about. The site explains how the new town on Yungay is located a mile North of the original town.
An idea that I have for creating a game to include avalanches would be to have different mountain peaks with different situations around them. Say one has residential buildings, another is a ski resort, and a third is only a highway. In the game you have to monitor the snow climate and decide if the conditions are to lead to an avalanche. If so, what options would you pick to secure the surrounding area and to get rid of the risk? The three options would give the player a chance to learn the risks with the three environments and how all three may need different types of mitigation to decrease the damage costs.
For my case study, an avalanche occurred in the towns of Yungay and Ranrahirca, Peru. The avalanche was caused by an undersea earthquake that collapsed the North slope of Mt. Huascaran. A slab of glacial ice and rock about 2,990 feet wide and 1 mile long began sliding down the mountain at approximately 335 km per hour. It covered a span of 11 miles. covering both of the towns. Due to the time frame this event happened there is not a lot of information about the event.
For avalanches that occur today we have three mitigation techniques. We can have controlled avalanches that we take action on before they naturally occur to limit the amount of damage, we can actively sustain forests in areas with avalanches, the vegetation acts as a natural barrier to the snow and slows down the avalanche. Or we can create structural barriers such as avalanche dams and retarding structures to limit the amount of damage that can happen. There really is no chance to mitigate whether the avalanche will happen or not though.
The Ancash Earthquake on May 31, 1970 triggered an avalanche that killed nearly 20,000 people. This avalanche happened in Peru and is one of their worst natural disasters. I chose this event because I have a fascination with avalanches and want to learn more about them.
My learning objectives:
- What speed did the avalanche travel at?
- What type of avalanche was it?
- Was there any negative impacts after to the topography?
For one of my case studies I chose to learn more about the Waldo Canyon Fire that happened in June of 2012. This event affected a large portion of Colorado Springs, and the San Isabel National Forest in Colorado. I’m choosing this event because it was one that I lived through and would like to know more about.
The three things that I am hoping to learn from this case study:
- How did this fire start?
- How did the fire spread so rapidly?
- What are the natural repercussions of this fire?
For this discussion I decided to look at the relationship between the climate change and the increase in geological hazards occurring recently. Below is the link:
While reading through this article there are a few things that i took note of; the first that I noticed in the beginning of the article the author states “Climate change may not be responsible for the recent skyrocketing cost of natural disasters, but it is very likely that it will impact future catastrophes.” This intrigued me because I thought otherwise. Another point brought up is that the number of storm formations may decrease due to the increase of heat and water vapor in the atmosphere caused by global warming, however, those same increases will most likely cause a spike in intensity of the storms that actually form. The increased water vapor acts as a fuel for the storms so higher water vapor means more intense storms. Another way that the global warming will affect the geological hazards is; the change in storm patterns will likely increase the amount of droughts and floods in areas. Rather than multiple rain storms occurring, the water vapor in the areas will accumulate in one large storm (or a few) causing multiple floods. But, with the large storms the water turns into run-off instead of being soaked into the ground to replenish ground water or to be used by vegetation causing the severe droughts. (This will be seen in Colorado with the lack of precipitation that they are receiving). The final thing to take note of is the increase in tropical storms that occur while the ocean temperatures increase along with the water vapor. The tropical storms will not only increase in severity and frequency, but they have the chance to occur in regions that are not typically affected by such storms.
Three things that I learned from this National Geographic article are: divergent boundaries in the oceans, magma from deep in the Earth’s mantle rises toward the surface and pushes apart two or more plates. Mountains and volcanoes rise along the seam. The process renews the ocean floor and widens the giant basins, At ocean-ocean convergences, one plate usually dives beneath the other, forming deep trenches like the Mariana Trench in the North Pacific Ocean, and India and Asia crashed about 55 million years ago, slowly giving rise to the Himalaya, the highest mountain system on Earth.
