:::THIS DISCUSSION IS BASED ON CONTROL OF EARTHQUAKE:::

An experiment in an oil field at Rangely, Colorado, has demonstrated
the feasibility of earthquake control. Variations in seismicity were
produced by controlled variations in the fluid pressure in a
seismically active zone. Precise earthquake locations revealed that
the earthquakes clustered about a fault trending through a zone of
high pore pressure produced by secondary recovery operations.
Laboratory measurements of the frictional properties of the reservoir
rocks and an in situ stress measurement made near the earthquake zone
were used to predict the fluid pressure required to trigger
earthquakes on preexisting fractures. Fluid pressure was controlled by
alternately injecting and recovering water from wells that penetrated
the seismic zone. Fluid pressure was monitored in observation wells,
and a computer model of the reservoir was used to infer the fluid
pressure distributions in the vicinity of the injection wells. The
results of this experiment confirm the predicted effect of fluid
pressure on earthquake activity and indicate that earthquakes can be
CONTROLLED wherever we can control the fluid pressure in a fault
zone:::
