Yes we are.
We have zoning laws and building codes that require buildings to withstand a major shake such as a 7.0. The Space Needle is a very good example. Even though it was built in 1962:
The Space Needle was built to withstand wind speeds of 200 mph (320 km/h), double the requirements in the building code of 1962. The 6.8 Mw 
Nisqually earthquake jolted the Needle enough in 2001 for water to slosh out of the toilets in the restrooms. The Space Needle will not sustain serious structural damage during earthquakes of magnitudes below 9.1. Also made to withstand
Category 5 hurricane-force winds, the Space Needle sways only 1 in (25 mm) per 10 mph (16 km/h) of wind speed.
Meanwhile Ohio and the midwest have done nothing. They have no zoning laws or building codes that require being able to with stand an earthquake.
They better get their butts in gear. They have a lot of work to do.
