The image above is from Collier County, Florida, and the lines running through the image are of different levels of hurricanes that have hit the area. Also, the dark blue coast indicates a deep water level, and as the water moves inland, the water levels decreases shown by the move to purple. The orange lines running through the map indicate a Category 4 or 5 hurricane, while the green lines indicate a Category 1 or 2 hurricane.
The image above shows schools, hospitals, and emergency rooms that are at risk by being in the tsunami inundation in Oxnard, California. The light blue area is the tsunami inundation zone, the dots within that zone are the schools, hospitals, and emergency rooms. There are a total of 42 schools, 3 medical centers, and 7 emergency rooms effected, for a total of 52 facilities at risk in Oxnard.
The above image is of the UW Eau Claire campus floodplain in a 100 year flood. While it looks like much of the campus is free from the flood, all of the lower campus is flooded as shown by the purple area covered. The upper campus is not flooded at all, but that's due to the severe increase in elevation.
This final map is for a flood in Eau Claire, WI generated for 800 feet. This is in comparison to the two images below, which are 790 and 780 feet. As you can see, this covers a larger area than the 790 ft. flood, and is substantially larger than the 780 ft. flood. What we can take away from this is the the ultimate difference between 780 feet and 800 feet. That number of people and overall area effected by 20 more feet is amazing.
This map is for a flood generated for 790 feet in Eau Claire, WI. Compare this to the same map below, which is the flood generated for 780 feet. The shaded blue area is much larger than the shaded purple area below. The biggest difference is the area on the eastern part of the map now being almost completely flooded.
The above image is the flood plain for the 100 year flood in Eau Claire, WI. The shaded purple area is the flood plain, which according to FEMA/EC is predicted to be 780 feet. The images above will include this same map, only with a flood generated for 790 feet, and above that, a flood generated for 800 feet.
The image above is again from Forest Fall, California on July 11, 1999. The green, yellow, and green area on the map are land parcels, and the light purple area surrounding these parcels mean there's a high volume of water in the area. The dark red right above the parcels represents a barren area, and the dark purple above the parcels indicates a steep slope. As you can see, there's also a steam that runs to the parcels. Everything this map shows explains why parcels should NOT have bee allowed in this area. The combination of steep slopes, high volumes of water, and barren areas right below the steep slopes all contributes to a very high risk area for mass wastage. Not only is there a high volume of water in the area, but the barren area makes it very easy for this water to reach the parcels. When understanding what all these different color shades indicate, it's clear this is an area with a high probability for mass wastage.
The image above is from Forest Falls, California from July 11, 1999. On this date, an intense storm hit the town that led to various wastage events, and the above image is an area that was hit by one of the strongest parts of the storm. As you can see, this area has a chain of elevated peaks that flow downward. The peaks appear pretty steep, and it's easy to see how a major storm would cause wastage events.
The map above shows different areas of the United States that are susceptible to landslides. As the map shows, the area most susceptible is the Appalachian Mountains because of their massive area and also warmer temperatures in the states in which the mountains are located. This causes many opportunities for landslides to occur. Lastly, there are labels in areas that are susceptible to Debris Flow, Undercutting, and Overstepening. These are all reasons for risk from landslides.
Above is an image of Mt. St. Helens post eruption in 1980. It shows where the most material loss occurred. Clearly, the most material was lost in the dark area towards the top of the image. This would make sense because a volcano doesn't erupt straight into the air. It's going to erupt to the side where it may be leaning or where there's more elevation. This explains why one side lost more material than the other.
This image above is before Mt. St. Helens erupted. You can see the after eruption image below. There is a clear difference, as we can see in the above image that the volcano comes to a clear tip. Below, that tip is gone, and there's more of a large circular indent that is left post eruption.
This image above is Mt. St. Helens after is erupted. You will see a clear a difference in the shape of the volcano compared to before it erupted. This is explained in the image above this one.
This image above is the same as the one below only with the added lahar layer which shows exactly how lahars flow from Mr. Ranier. This does an excellent job of showing how the lahars flow from the very top of the volcano down the side to the lower elevated areas. The majority of these areas are riverbeds, which further explains why lahars can be so destructive in terms of human geography. Many of our cities and town will be located close to water sources. If a lahar flows down riverbeds as they are known to, chance are the lahar will come across a few towns and cities as it flows.
This image above shows much more of the elevation/texture of the area we're looking at than the DEM below. It does an excellent job of really showing the different elevations, something the DEM does as well, but seems much more clear and precise.
This image above is from the program ARCSCENE. It shows a partion f Mt. Ranier that I'll be working with in the above images with ARCSCENE.
This image above is a picture of world volcanoes created in ARCMAP. As you can see, there are a substantial among of volcanoes located in the Ring of Fire (Western Asia), Italy, the United States, and even Russia. These also happens to be the countries with the most volcano activity. The map also shows the way that the tectonic plates are moving, which further explains why these countries listed are the leading countries in volcano activity.
This map above is the the exact same as the map below only this shows Peak Ground Velocity. The areas with the highest damage density, and highest Peak Ground Acceleration, are also the areas with the highest Peak Ground Velocity.
This is the same map as below, only now we've take out the building status and liquification layer and added a stations layer indicated by the green triangles, and also a Peak Ground Acceleration layer. The stations are located on the very edge of the high acceleration areas. High ground acceleration is indicated in the darker areas of the map. This also happens to be the part with the highest building damage density if we compare it to our map below.
The image above is a map from ARCGIS with three map layers: Building Damage Density, Building Status, and Liquification in California. The dark blue covered areas mean high building damage density. These layers are Northridge, Sherman Oaks, and patch between West Hollywood and Santa Monica. The red, yellow, and green dots represent building status. Red indicates the building is unsafe, yellow means limited entry, and green is safe. It appears the majority of the area is green and yellow, with a few clear red patches. Lastly, the liquification layer can be seen with the yellow covered areas by Fillmore, and surrounding the high damage density areas. Yellow means high liquification, and there's also a red area south of Santa Monica which means very high liquification.
The image above is from ARCGIS and shows recent deposits of earthquake activity. As you can see, there is quite a bit of activity in the Western United States and also along the East Coast. This makes sense considering this is also where there are tectonic plate boundaries.
This image above is my map for what NOT to do when trying to plan a for a hurricane. We were instructed to create a town that would be poorly prepared for an environmental hazard to hit, in this case a hurricane. I tried to put all the important buildings, like the hospital and school, right on the water. Also, I built the cheapest houses possible, meaning they'd put up the least resistance to a hurricane.
This picture above is of my town after the tsunami. Obviously, my preparation wasn't great. I don't know how much I could really change though, and it just goes to show the strength that some hazards have. By far my biggest mistake was to not build the hospital farther back from the water. That building was completely destroyed, and it was poor planning on my part.
The image above is a map I constructed when playing a hazards game online in which we had to prepare a town for a hazard strike. In this case, it was a tsunami, and my approach was to put as many barriers between the water and building as possible. This explains the sand dunes and trees.
This is some live footage of the Yosemite wildfire, and some different ways it's being fought by civilians and firemen.
