It's really easy actually. An example would be if you were given a map that had two of Hawaii's islands on it and gave the age of each island. You would measure the distance between the two islands and divide it by the difference in ages of the islands. Also works with just an island and the location of a hotspot and one age. Just divide distance from hotspot by age.

The easiest thing to do for these is save a space on your "cheat sheet" for because there isn't a guarantee they will be on the test.

Eak posted this in the Road Scholar thread, but profiling a mountain is the same thing as profiling anywhere else.
eak227 wrote:Here's how we used to do it:

Take a piece of printer paper, and line up the 2 points, placing big marks at each end point. Now, going along between the endpoints, at every contour line you see, place a little dash on the edge of the paper at the spot. So by the end you'll have a sheet of paper with a bunch of little dashes running along the edge of the sheet. It is also helpful to record the elevation of maybe every third or fourth mark so you don't lose your spot.

Now, figure out your min and max elevation between the two points by looking at the map. Set up an appropriate scale on your chart, with elevation going up the Y axis and just location along the X axis.

Take your piece of paper, and line up the left end point with the x=0 spot on your chart. Make a little dot on the appropriate line of elevation. Now, keeping the left end point on the x=0 spot, go through and place a little dot at every elevation dash you made on that sheet of paper. It can be difficult to keep track of what exact elevation each dash is for, so be careful. Once you're done, you will have a series of dots mapping out a nice curve, perfectly scaled to match the topo map. All that's left is to connect the points as smoothly as realistically as possible and you'll have a perfect profile.

mercali is intensity of shaking, Based on amount of damage

richter is energy released, at the focus
