Fortunately no lives were lost, but 10,000 people were displaced or evacuated, more than 2,000 homes were damaged or destroyed, and tens to hundreds of millions of dollars in damages occurred. The model includes simulations of physically plausible flood events capable of causing losses far greater than have been observed historically, allowing (re)insurers to prepare for the potential financial impacts of the next flood catastrophe. What would happen if the Shasta Dam broke? Can you tour Hungry Horse Dam? Sidewalk streams?. A major earthquake could unleash "potentially catastrophic" flooding from a dam in Oregon that would threaten the state capital and other communities downstream, according to the U.S. Army Corps of Engineers.

Stanley agreed. How long will it take for the concrete in Hoover Dam to fully cure? Although the quake was powerful enough to generate a 3-foot-high wave on Lake Chabot, the dam emerged with no apparent damage. To understand EBMUDs confidence that a dam built within a quarter-mile of a dangerous fault will stand up to a violent shaking, lets take a look at how the dam was first built nearly 150 years ago and how its been maintained since.

Flood waters hit northeast Bakersfield within six hours, traveling fast enough and deep enough to knock people off their feet and float a car off its wheels. But they're really living, breathing structures that must withstand awesome physical forces. Understanding flood risk and how it is correlated with wind exposure, is required for management of an overall book, risk tolerance and accumulations. But Dean noted that recent tests of the Hungry Horse Dam itself and its surrounding rock abutments performed well in earthquake tests. The U.S. Army Corps of Engineers, which operates Libby Dam on the Kootenai River, refused to release information for the same reason. The potential hazard the dam poses goes beyond the fact it's a century and a half old and that it's perched above a densely populated plain. However,even if it were 100% self-sufficient, the loss of hydroelectric power in surrounding areas could lead to the Vegas electrical grid being diverted to them.
