Risk Management has four options: reduce the risk, remove the cause, manage the harm, and transfer the risk. Since you cant control earthquakes you can't remove the cause. You can transfer the risk with insurance, but thats not your question. Reducing the risk: 1. Build without windows. 2. Apply a clear film that adhesively binds glass. 3. Use a different construction technique to "float" windows. Etc. manage the harm: 1. build with glass fall zone clear space (keeps people from glass falls). 2. Build lower to ground (minimizes fall of glass). Etc.
