New Dams Being Considered to Handle West’s Water Needs
An article in the Seattle Post Intelligencer discusses how the era of building massive dams that ended in the late 1960s with the completion of Glen Canyon Dam may be on its way to a resurgence because of booming populations throughout the west and a desperate need for water. This comes at a time when the USBR and other agencies are in the process of tearing down some dams. Of course the environmental hurdles and opposition to new dam projects will likely kill many of the projects before they get started. But in the absence of any kind of limits on population growth, there may not be many other options. Read on to see where major dam projects are being considered. (Photo by Molas)

There are two issues here :
(1) Why this prophecy now, what credible seismic event/EQ was considered while designing the project layout, if presence of Calaveras Fault in vicinity as close as ~1.6km was known?
(2) Now with this info, what stabilisation strategy is being adopted/conceived to tackle this scenario?
