Natural hazards

YEC Geo's curator insight, June 14, 2014 1:10 PM

In the lower map, the location of the house is marked by a yellow pushpin inside the solid red square.  Some geological background--this poor house has the misfortune to apparently lie directly upon the contact between two carbonate formations (marked by the white dotted line), and to also be on the erosive edge of a bend in the river. Both factors probably contributed to the demise of this particular home, which was eventually set on fire: https://tinyurl.com/nw7mfd2

 

 

One thing to notice is how straight the cliff edge is upon which the house is built.  Knowing that, I'd have to say that if I had a house located on the straight cliff edges within the dotted red squares I've made on the map, I'd be worried.

The eprverse effect of maps is that they give the false idea that our physical world is steady. It's the case as we see here for coastal environments, but also for rivers.
Ryan G Soares's curator insight, December 3, 2013 11:12 AM

I find it quite facinating how the world changes. Some of the worlds most beautiful things may not be here 30 years from now. It is quite humbling that things that man builds can be taken away by Mother Nature. As the years pass the memories made will be vanished by the environment.

Hector Alonzo's curator insight, October 14, 2014 11:40 PM

Interesting how the physical landscape of one country can be effected by the surrounding water that connects two different countries. To have some areas of Louisiana be overtaken by the Gulf of Mexico is astounding, seeing an area that has stayed relatively the same be wiped off the map is interesting

The cause of the pink lake is still a mystery. Scientists believe the pink could be due to lack of nutrients or other substances. I think this is truly remarkable! Its beautiful to say the least. 

Hector Alonzo's curator insight, December 15, 2014 11:44 PM

The pink lake, Lake Hillier,  located in Western Australia is stunning. The aerial view of the lake makes the lake seem unreal that is was is fascinating. What gives the lake its pink color is a mystery, but it may be from bacteria, but it shows how some places in the world are affected differently than others and it produces remarkable results.

Nicole Kearsch's curator insight, December 17, 2014 1:48 AM

Now this is bizarre.  A pink lake and no one is really sure as to why it is pink.  It is not on the top of my list of places to go swimming, that is for sure.  Although scientists don't seem too concerned about the safety of the lake for people but are curious as to what is causing the lake to be pink.  Thoughts on algea and bacteria levels or the amount of salt are included in the potential reasoning for the pink color.  Even on google earth you can see that the lake is in fact pink.  Even when scientists come to a conclusion as to what is causing the pink colored lake, as far as it isn't causing any environmental issues, I think that the lake should be left pink as a type of wonder of the world attraction for people to see.

I have never heard of these before. I thought it was really interesting how they a made. It is confusing however how the article talks about lighting being able to create these almost every time it strikes then how come they are not more common?

If you want to see how to coax nature into producing these things while watching a rom-com, see "Sweet Home Alabama" w/Reese Witherspoon.
Thomas D's comment, April 29, 2013 4:53 PM
I find this article very interesting, I have never heard about or seen this in my life. I had no idea that these types of things could be formed from a lightning strike. The article is a little confusing however saying that these can happen all the time. Maybe it’s because I’ve never seen a lightning bolt directly hit the ground in front of me and see the reaction of the earth. I just find it hard to see as this being the first time I would come across something like this.

EARTH Masterpieces

The natural landscapes shown as captured by satellite imagery is as beautiful as anything artists have ever created.  Some of the colors shown in the video may seem otherworldy.  Most of those color anomalies are due to the fact that remotely sensed images have more information in them than just what we see in the visible portion of the electromagnetic spectrum.  Some of these images are processed to show different bands so we can visually interpret data such as what is in the near infra-red band, skewing the color palette.

Peter Phillips's comment, October 5, 2013 7:31 PM
All rivers move. Those that have a wide, flat basin meander most. Those meanders can be even more dramatic than in this image, snaking 10's of kilometres sideways over time. Combine this action with geological upheaval and it gets even more interesting. Check out images of the Murray River in Australia from space.
Matthew DiLuglio's curator insight, December 6, 2013 11:34 AM

Lol... the first words that went through my head were h--- (heck) yeah.  David Bowie... sung by an astronaut... okay, back to Geography. I thought that the rivers reminded me of something I thought of during the talk in class about lava rock being changed into other kinds of rocks over time, and cycling around.  I thought on a larger scale, about this universe, and I have read before that people are studying different areas of space-time fabrics, trying to find origins of the Universe, and answers to other existential questions.  I suppose that if one could trace patterns of rivers, and if one could trace patterns of rocks, to find where they came from, and why/how they came where they came, then by examining the (assumedly tattered and marked) fabrics of space and time, people would be able to determine origins of everything from the beginning of what existed before all universes, and also the origins of life forms.  I enjoyed the movie Prometheus, which was directed by Sir Ridley Scott, and I had to say that I thought that the messages found on rocks in caves, as a catalyst that lead the cast to go visit an alien world that had something to do with human origins, could be very literally taken.  If there are clues in rocks, why wouldn't there be other clues, possibly in celluar components of life forms, or space and time?  Applying the idea of studying rocks and rivers and other physical geographical pursuits to the idea of applying it on a gigantic scale greatly appeals to me.  I believe that humans will find some answers that way, but I hadn't directly realized just that until we mentioned some stuff about physical geography, and glacial forces carrying and spreading out rocks, and deposits and erosion.  After all, the Milky Way has origins, so why believe that we came from the Milky Way, rather than beyond?

Shelby Porter's curator insight, December 11, 2013 10:23 PM

Normally we see erosion on a piece of land over a long period of time. In this short video, we see what erosion can do to in mere minutes. It is scary to think how much the roads we drive on are eroding right underneath our cars. It is amazing how much the environment around us can change due to the weather. 

megan b clement's comment, December 16, 2013 12:30 AM
This video is crazy! It shows the erosion of a road during a storm. The water was supposed to run under the road and flow through a large pipe. As you can see after watching the video the road eventually erodes and then the pipe begins to bouy up and down. Later the road is completely deteriorated and the pipe ran down the river with the rest of the road.

This image tells the story of Akimiski Island's recovery after the last Ice Age, when it was covered with glaciers so large they sunk the island. The layered scarring on highlighted in the lower image was caused by waves as the island rebounded and rose along with the rising oceans as glaciers melted.

 

I wonder what forces are at work to raise the elevation of the island, possibly just decompression from the millions of pounds of pressure the island was under during the Ice Age.

In a world where photoshop has made the unreal seem ordinary, these unearthly seemingly landscapes might seem likely fakes.  The world can be that extraordinary.  Pictured above is the "Door to Hell" in Turkmenistan.  Rich with natural gas, Soviets were drilling in 1971 when the drilling rig collapsed and left a huge (230 feet wide) hole.  In an attempt to stop gas leaks they hoped a fire would burn off any discharge, but it is still burning today.  Enjoy this gallery of 25 'unnatural' images.

This article on buzzfeed shows 25 images that can amaze you. In Mt. Roraima, Venezuela there is a slab of land that seems to be suspended in the clouds. The Metro in Stockholm, Sweden resembles a space station in the rocks. The tunnel of love in the Ukraine looks like a path carved out of bush and also a romantic place for a date. The tulip Fields in Lisse, Netherlands looks like a grounded rainbow. Lapland, Finland is home to massive natural snow creatures. The mountains of Zhangye, China resembles the colors and look of Zebra stripe gum. Lake Rebta in Senegal looks like your floating in tomato soup.
