Which of the following describes why earthquakes are common along the San Andreas Fault quizlet?

Strike-slip earthquakes are common along the San Andreas fault. Shallow, intermediate, and deep earthquakes occur along a subduction zone. Very little seismicity occurs in this area, which is far from a plate boundary. A megathrust between the two plates creates large earthquakes.

What is an earthquake and how do earthquakes generally occur?

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don’t just slide smoothly; the rocks catch on each other.

What is the probability that a large earthquake M 6.7 will occur in the San Francisco area between 2003 and 2032?

a 62%

What are the four segments of the San Andreas Fault?

San Andreas Fault
Segments	Calaveras, Hayward, Elsinore, Imperial, Laguna Salada, San Jacinto

Tectonics

What will happen when the San Andreas Fault ruptures?

CoreLogic, a business analysis service, estimated a Southern San Andreas fault rupture will cause 3.5 million homes to be at risk with $289 billion in reconstruction value. Water, electricity and gas lines cross the San Andreas fault in Los Angeles. They break during the quake and remain unfixed for months.

Why is San Andreas Fault dangerous?

The research finds that the 2019 Ridgecrest, California, quakes shifted underground stresses, making the San Andreas fault—the state’s longest and most dangerous fault—three times more likely to rupture. “But that is because we do not appreciate the way the network of fault lines connect across the state.”

Would a 7.1 earthquake destroy the Hoover Dam?

Blast the dam loose from the rock on both sides, and Hoover will just sit there while the water squirts around the sides where the rock was damaged. It would be very, very hard to significantly damage Hoover with a quake of any possible magnitude.

Can the San Andreas Fault cause a tsunami?

The San Andreas fault cannot create a big tsunami, as depicted in the movie. Local tsunamis might be generated along the California coast, if the shaking from an earthquake on the San Andreas fault triggers underwater landslides or if there is slip on a smaller offshore fault.

What is wrong with San Andreas movie?

Physically, an earthquake-triggered tsunami happens at a subduction fault, which San Andreas is not. San Andreas is a land-based fault, which moves along the rupture horizontally (by the way, the fault would never open up as it does in the movie, leaving a gaping chasm in the ground).

What is the moral lesson of the movie San Andreas?

The movie taught everyone that natural disasters may come even in the most unexpected time. Money couldn’t do anything just to help us to survive. Just like in the movie, the main character, and his wife realized that their family is the most important thing in this world regardless of other material things around us.

Why is the San Andreas Fault so popular?

California’s sleeping giant, the San Andreas Fault, marks the slippery yet sticky boundary between two of Earth’s tectonic plates. It is responsible for the biggest earthquakes in California, up to at least magnitude 8.1.

What is the highest earthquake the Hoover Dam withstand?

Studies have been done on the Hoover Dam (and have been done on most large dams in the US) that indicate that the maximum credible earthquake that could occur in the dam’s area is a 6.75 on the Mead Slope Fault.

What is the lifespan of the Hoover Dam?

10,000 years

What would happen if Hoover Dam failed?

If catastrophe struck the Hoover Dam and it somehow broke, a catastrophic amount of water from Lake Mead would be released. That water would likely cover an area of 10 million acres (4 million hectares) 1 foot (30 centimeters) deep. Approximately 25 million people depend on water from Lake Mead.

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.

Which Dam is the largest dam in India?

Tehri Dam

Do dams block the migration of fish?

Dams can block or impede migration and have created deep pools of water that in some cases have inundated important spawning habitat or blocked access to it. Spilling water at dams over the spillway is an effective means of safely passing juvenile fish downstream because it avoids sending the fish through turbines.

What is the relationship between dam and earthquake?

Answer. Dams by itself do not cause any earthquake. The purpose of any dam is to impound the flowing water. This leads to formation of reservoir in which a large portion of land is submerged along with the river course on which the dam is made.

What types of sites or artifacts will be lost when the Three Gorges Dam is completed?

Over the course of dam building, many artifacts from the Three Gorges area went up for sale through dubious channels, most notably a bronze spirit tree dating to the Han dynasty. Though these pieces have been saved from submersion, their context has been destroyed, causing the loss of valuable archaeological data.

Can dam construction cause earthquakes?

Earthquakes can be induced by dams. The most serious case may be the 7.9-magnitude Sichuan earthquake in May 2008, which killed an estimated 80,000 people and has been linked to the construction of the Zipingpu Dam.

How does high CO2 pressure cause earthquakes?

Two scientists have found evidence that underground carbon dioxide injection in oil and gas fields may cause earthquakes, a finding that suggests carbon sequestration projects could shake the earth, too. CO2 storage facility at a Norwegian offshore gas facility. …

How can the injection of co2 into the ground in North America lead to earthquakes?

Carbon capture and storage likely to cause earthquakes, say Stanford researchers. Stanford geophysicists say earthquakes triggered by underground CO2 storage, while probably too small to cause major damage, could release stored CO2 into the atmosphere.

Are earthquakes associated with climate change?

Scientists know earthquakes can be triggered or inhibited by changes in the amount of stress on a fault. The largest climate variable that could change fault stress loads is surface water in the form of rain and snow. Lundgren says several studies have supported such correlations.

What causes earthquakes?

An earthquake is caused by a sudden slip on a fault. 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. In California there are two plates – the Pacific Plate and the North American Plate.
