Disaster Mapping: Hurricane Irma, Mexico Earthquake and Bangladesh Floods

Disaster Mapping: Hurricane Irma, Mexico Earthquake and Bangladesh Floods | STEM Connections | Scoop.it

This week has seen disasters and destruction on an unprecedented scale, and the HOT Community has activated to respond. Hurricane Irma is the largest Hurricane ever recorded, and has torn death and destruction through the Caribbean. Destruction on some islands is estimated at 95%, affecting the lives of 1.2 million so far, and on track to cause severe destruction across the entire Florida State, where mass evacuation is currently underway. Barbuda’s prime minister, Gaston Browne, described the damage as absolutely heart-wrenching. 'The island is literally under water and barely habitable,' Browne said. 'About 95% of properties are damaged, there is a serious threat of disease. Additionally, those already affected by Irma fear a second brutal battering by Hurricane Jose.'"

Want to see geographic knowledge and geospatial skills in action?  Crowd-sourced mapping is increasingly an important resource during an emergency.  Poorer places are often not as well mapped out by the commercial cartographic organizations and these are oftentimes the places that are most vulnerable to natural disasters.  Relief agencies depend on mapping platforms to handle the logistics of administering aid and assessing the extent of the damage and rely on these crowd-sourced data sets.  My students and I join OpenStreetMap (OSM) projects, especially when there is a major humanitarian need...it's a great way to make service learning and geospatial technologies come together. The projects that are marked urgent by the Red Cross are all in Haiti right now.  Here are is a video playlist that explains the project and how you can help if you are new to OpenStreetMap (OSM).

Why Hurricane Categories Make a Difference

During a hurricane you usually hear meteorologists refer to its intensity by categories. If you don't know the difference between a category 1 and a category 5 hurricane, The Weather Channel meteorologist Mark Elliot breaks it down for you.

With Hurricane Matthew having just hit Haiti (video) and Cuba, it now poised to strike Florida. Many are unsure what the term “category 4” actually means because they are unfamiliar with the Saffir-Simpson Hurricane Wind Scale.  This video is a good introduction to what this means to people in the path of the hurricane. As we monitor this (and future) situation, these are my favorite digital globes that display wind speeds and a few other of Earth’s physical systems. What is beautiful and majestic from one scale can be horrific and catastrophic at another:

Louisiana in Tough Shape

Louisiana in Tough Shape | STEM Connections | Scoop.it
Unlike the many maps we have seen that show what Florida, Boston, or some other coastal location would look like with higher sea levels, the figure above compares the iconic outline of Louisiana with the present-day outline of its dry land. An important caveat is that some of the removed areas are wetlands, meaning they are not under water all the time, but those lands are not available for most human uses (aside from fishing), so this outline warrants attention.

Tsunami Animation

"The largest earthquake ever recorded by instruments struck southern Chile on May 22, 1960. This 9.5 magnitude earthquake generated a tsunami that crossed the Pacific Ocean, killing as many as 2000 people in Chile and Peru, 61 people in Hilo, Hawaii, and 142 people in Japan as well as causing damage in the Marquesas Islands (Fr. Polynesia), Samoa, New Zealand, Australia, the Philippines, and in Alaska's Aleutian Islands.  To see how this tsunami compares with two recent tsunamis from Chile, please watch http://youtu.be/qoxTC3vIF1U "

In 1700, Japan was hit by a tsunami; they knew that tsunamis were caused by earthquakes, but there was no earthquake of that magnitude in Japan that could have caused it.  They called it the Orphan Tsunami, and it puzzled everyone.  Centuries later, data confirmed that a massive earthquake in the Pacific Northwest occurred in 1700 and it's tsunami traveled across the ocean much like the this computer simulation of the 1960 Chile earthquake.

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake

Visualized: How the insane amount of rain in Texas could turn Rhode Island into a lake | STEM Connections | Scoop.it

"It's difficult to comprehend the ridiculous amounts of water that have fallen in such a short time in a state that, until recently, had been in the grip of a historic drought. But one place to start would be to look at reservoir levels in the state. In the past 30 days, Texas reservoirs have gone from being 73 percent full to 82 percent full, according to data maintained by the Texas Water Development board. All told, about 8 million acre-feet of water have flowed into the state's reservoirs."

Just how much of water is 8 million acre-feet?  It's almost impossible for most people to visualize that, but this series of graphics is designed to put the scale of the recent flooding in Texas into perspective (and yes, I love that Rhode Island is almost a unit of measurement).

Andrew  was bad, Katrina was most memorable

Giselle Figueroa's curator insight, September 21, 2014 1:24 AM

The worst Hurricane that I remember is Hurricane "Katrina" in 2005. I was living in Puerto Rico but I remember seen the devastating news. The largest number of deaths occurred in New Orleans, which was flooded because its levee system failed. Also "Katrina" was the hurricane that has caused more economic damage as well as one of the five deadliest hurricanes, in the history of the United States. It was a very sad event. I hope that does not happen again.

Jake Red Dorman's curator insight, October 29, 2014 1:51 PM

My father is actually good friends with a guy who he went to school with that specifically help clean up after natural disasters such as hurricanes. I got to talk to him for a little bit about hurricane Katrina, since that was his most recent natural disaster that he helped with at the time. He said it was probably one of the, if not the worst of the natural disaster to help clean and rebuild. He spent the most time with that natural disaster than any others he said. From de-flooding homes, to destroying homes, to rebuilding homes was one of the most strenuous things he has ever had to do in his career.

The amazing geothermal activity in Yellowstone National park annually brings thousands of tourists to the region.  The reason why these geysers, hot springs and fumaroles are there is because of the what is just below the surface.  Watch a video (the 2 minute version or a 44 minute version) to see why this natural wonder is also a major geologic threat for earthquake and volcanic activity, which explains the reasons for this weekend's earthquake.   Not to be an alarmist, but this is why some fear another major eruption soon.

Factory farming practices are under scrutiny again in N.C. after disastrous hurricane floods

Factory farming practices are under scrutiny again in N.C. after disastrous hurricane floods | STEM Connections | Scoop.it
As fecal waste and bacteria flow from hog lagoons into the water supply, North Carolina is revisiting a contentious battle between the pork industry, health experts and environmentalists.

 

In regions where hog farm density is high, there is an overall poor sanitary quality of surface waters. The presence of mass-scale swine and poultry lots and processing plants in a sandy floodplain – a region once dotted by small tobacco farms – has long posed a difficult dilemma for a state where swine and poultry represent billions of dollars a year for the economy. [Past] hurricane’s environmental impact in North Carolina were so severe in part because of the large number of hog lagoon breaches. Following Hurricane Matthew, the department has counted 10 to 12 lagoons that were inundated, with floodwaters topping the berms and spreading diluted waste.

Their is nothing on earth more amazing and terrifying than a volcanic eruption. As mentioned in class, Mexico has a number of active volcanos. The most troubling one is the volcano near Mexico City. An Eruption of that volcano would spell doom for portions of Mexico City, and a wider doom for the whole nation. As a primate city, destruction in Mexico City would be devastating to the overall health of the Mexican economy. We can only hope that Mexico will be prepared to deal with the ramifications of such an eruption.
