<br />GEOLOGY <br /> <br />~ <br />C~ <br />~ Seismic <br />~ <br /> <br />1. Question - Would the dams be in danger from earthquakes? <br /> <br />Answer No. <br /> <br />2, Question <br /> <br />Answer <br /> <br />The project area is in Zone 1 on the Environmental <br />Science Service Administration seismic risk map - this <br />indicates low risk, with minor damage to structures <br />such as houses in the event of an earthquake. It <br />would not be expected that such low magnitude events <br />would damage rolled earth embankments constructed by <br />modern methods. <br /> <br />Would the reservoir induce seismic activity? <br /> <br />- No. <br /> <br />Induced seismic activity from compressive loading is <br />associated with very large reservoirs in some areas, <br />These small reservoirs would have no such effect. <br />Seismic activity from water introduced into underlying <br />strata would not be expected since basement rock at <br />both reservoirs is relatively impervious shale, <br />
