Not sure if you guys have agreed to an area to build. But here is something to think about:
We should want to build in an area that is:
-Geologically Stable
-Politically Stable
-Sheltered from severe weather (hurricanes, tornadoes, etc.)
-Not under threat from other weather/geologic events (volcanic eruptions, tsunamis, earthquakes, etc.)
So lets start with the first criteria (Geologically Stable).
-----------
The easiest way to satisfy this requirement would be to build on a "Shield." A shield is a geologic area, that is essentially 'dead rock,' meaning there is very little or nothing going on geologically. They hardly ever have earthquakes, and the earthquakes they do have are a totally different variety than what you might imagine at the sight of that word.
Shields are the core of continental plates, there are 12 shields shields:
-Canadian
-Amazonian
-Guiana
-Platian
-Baltic
-African
-Australian
-Arabian-Nubian
-Antarctic
-China-Korean
-Angaran
-Indian
Of these, the Canadian and Australian shield are the most promising. They are in politically stable areas that also happen to be fairly tolerant, they are almost entirely inland, have no active volcanoes, and are not vulnerable to tsunamis, hurricanes, tornadoes, or earthquakes.
Regions included in the Canadian Shield:
-Greenland
-Quebec (north of St. Lawrence River)
-Ontario
-Adirondack Mountains
-Upper Peninsula of Michigan and northermost parts of the Lower Peninsula
-other less notable areas
Regions included in the Australian Shield:
-Western half of Australia
So now we know some good places to build. What comes next is which area has greatest access to water? Obviously the Canadian shield has superior access to water, specifically in the Quebec, Ontario, and Michigan portions. For that reason we should consider those areas.
However, they aren't known for their warm weather!
So we might want to look at water features on the Australian plate. But then comes COST. Will getting access to fresh water on the Australian plate be cost prohibitive? Or should we tough it out and commit to the short summers of the Canadian Shield? Or is the land in those favorable areas of the Canadian Shield in-and-of-itself cost prohibitive?
All things up for discussion.
But, that's why we're here! Looking forward to your thoughts. Who is going to get data on the price/availability for land with water-access on the Australian shield? Who is going to get that same data for the favored areas of the Canadian shield?
