10.15

In reconsidering the assignment I've decided to construct a layering map. This map will condition how the earth as a whole reacts and exists through a terrestrial impact event. When an impact occurs many large scale processes take place including the displacement of atmoshpere, land, water (megatsunami's), the occurance of global firestorms, acid rain, temperature abnormalities, seismic shaking, ejecta deposition, air blasts, and thermal radiation.
This is a lot of information. For this mapping I have selected thermal radiation, ejecta deposition, and air blasts to use as information for layering ontop of a topographic mesh model of the earth (seen below). To gather data I have located a program created by scientists at the University of Arizona. This is a web-based program that calculates the effects of an earth impact. The program can be located here. Using this program I will relate my chosen processes in terms of distance from a given location on the earth.
Essentially mapping how the effects of a terrestrial impact diminish as distance from the point of origin is increased.

i'm glad you finally read the corner readings and happy to see the progress - it is a good start. seems like you should model other data and consider how animation will facilitate this study and what you hope it to reveal

it also seems like the impact effects calculator will be helpful in modeling more data based on information you generate from there. the historical data for:
Energy:
Atmospheric Entry:
Major Global Changes:
Air Blast
will be interesting to see and maybe some type of future condition can be interpolated.
