From our first lab Tsunamis, the picture here is what I built for my town. This is used in lowering risk for tsunamis by being able to simulate a tsunami for a certain town.
Shown above is an image from our volcano lab. The black circle on the left side is indicating the Ring of Fire.
Here is a graph from Lab 7. This pattern shows the high and low values of the elevation. The darker the area of the slope will have a lower value for the slope layer for mass wastage.
