How do geologists use seismographic data to make maps of faults? Seismographs detect the reflected seismic waves and geologists use this data to map the length and depth of the fault. Why do geologists collect data on friction along the sides of faults? So they can try to predict the probability of a large earthquake.
The total cost for a concrete garage floor, including concrete, labor, supplies and equipment, varies region to region because of geographic variables. The total cost for a 400-square-foot garage floor in San Francisco ranges between $3.91 and $4.28 per square foot and between $3.26 and $3.60 per square foot in Atlanta.In suburban Chicago, the same floor will cost between $3.70 and $4.05 per square foot.he total cost for a 400-square-foot garage floor in San Francisco ranges between $3.91 and $4.28 per square foot and between $3.26 and $3.60 per square foot in Atlanta.

Ignoring any maintenance costs, asphalt is generally much cheaper to install than concrete. On average, the cost per square foot for asphalt will run between $2.50 to $4.00. Fluctuations in crude oil prices can cause fluctuations in asphalt prices but the price will remain around this range.oncrete, on the other hand, can run between $4.00 to $6.00 per square foot for basic installation and can cost more depending on different finishes and detail. Itâs not unheard of to have a stained concrete driveway with a smooth finish cost over $15.00 per square foot.
