This is my proposal to manage earthquakes.Evacuate the quake zone. Pump sea-water into the fault. Set off several large explosions in the fault. Force an earthquake of predictable magnitude, releasing a measurable quantity of stress-energy.Geologists have a reasonable idea of how much stress there is in any particular fault. From that they can estimate how large the largest (likely) quake will be.So the local government agency decides upon an acceptable limit, based upon various local criteria, including building codes etc. Then, when the rock-stress-limit is reached, the local population is given sufficient warning / evacuated, then the quake is forced.This will need to be done maybe once every 20-200 years. Depending on location.Better than waiting for a Haiti-style disaster? (Ask the politicians)
