technology has allowed tensions
to be relieved on a regular basis. This is how it works
1. Explosives are set up along the faultline at regular spatial intervals.
2. At regularly timed intervals, the explosives are set off.
3. Movement along the faultline becomes regular and smooth, instead of sudden and destructive.
After a natural earthquake's aftershocks have died down is an ideal time to begin this process, because there is little threat of causing larger earthquakes.
On the other hand, even without natural earthquakes, we can build up to smooth techtonic movements by ever increasing the power and frequency of intentional explosions. The rest of this node is left as an exercise to you, gentle reader.
