The 59-year-old dam, which stands 726 feet high, provides power to areas of California, Nevada and Arizona. “Crews did a complete visual inspection of the dam and found no damage,” Walsh said. He said the dam was built to withstand “a very strong earthquake, in the range of 8.0.”
Large dams are required to be able to withstand an earthquake with a return period of about 10,000 years, whereas buildings and bridges are usually designed for an earthquake with a return period of 475 years. This is the typical building code requirement, which means the event has a 10% chance of being exceeded in 50 years.
Where the water would do immense damage is in the lakes below Hoover dam. It turns out that below Hoover dam is another large lake called Lake Mohave, which is held in place by Davis dam, and below that is Lake Havasu, held in place by Parker dam.
Hoover Dam in the US built in the 1930s was the first concrete dam designed against earthquake where both the inertial effects of the dam and the hydrodynamic pressure of the reservoir were taken into account.

Do large dams cause earthquakes?
“When the dam was built, a lake was created. The higher water levels created greater pressure in pore spaces in rocks at lower depths, a known trigger for earthquakes. This is the same effect that can lead to earthquakes when wastewater is pumped into the ground,” Encarnacion said.
Would an earthquake break the Hoover Dam?
The recent earthquakes that rattled Southern California and parts of Nevada didn’t damage Hoover Dam. Following the 6.4 and 7.1 magnitude earthquakes that first struck near Ridgecrest, California, on July 4th and 5th respectively, Reclamation staff immediately inspected the dam and found no evidence of any damage.
Are dams earthquake proof?
(b) Virtually any well-built dam on a firm foundation can withstand moderate earth- quake shaking, say with peak accelerations of about 0.2g with no detrimental effects.
Is there any relation between a dam and an earthquake explain?
Earthquake and dams are related because of extra water pressure created in microcracks near a reservoir. Dams are often built-in active earthquake areas. Depth of the reservoir is one of the most important factors, but the volume of water also plays a significant role in triggering earthquakes.
What causes of earthquakes?
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.
How can we protect a dam?
The upstream face of a dam is commonly protected against wave erosion by placement of a layer of rock riprap over a layer of bedding and a filter material. Other material such as concrete facing, soil-cement, fabri-form bags, slush grouted rocks, steel sheet piling, and articulated concrete blocks can also be used.
Can dams trigger earthquakes?
“When the dam was built, a lake was created. The higher water levels created greater pressure in pore spaces in rocks at lower depths, a known trigger for earthquakes. This is the same effect that can lead to earthquakes when wastewater is pumped into the ground,” Encarnacion said.
What type of dam is best suited for an earthquake?
Concrete and embankment dams are much better suited to carry horizontal loads than buildings and bridges. Large dams are required to be able to withstand an earthquake with a return period of about 10,000 years, whereas buildings and bridges are usually designed for an earthquake with a return period of 475 years.
