A giant earthquake will strike California this summer. Skyscrapers will topple, the Hoover Dam will crumble and a massive tsunami will wash across the Golden Gate Bridge. Or at least, that’s the scenario that will play out on the big screen in San Andreas.
What will happen if the big one hits the west coast?
Here's what will happen if the big one hits the West Coast. Narrator: On July 4, 2019, Ridgecrest, California, was hit with a 6.4 magnitude earthquake and then a 7.1 just one day later. But neither of these compare to the long-awaited big one, which scientists predict will eventually rattle the golden coast.
How hard will the next big one hit California?
More than 100 years on, it's hard to predict exactly how hard the next Big One will hit. John Vidale, director of the Southern California Earthquake Center and affiliate professor at the University of Washington, told Newsweek it won't look like in the movies—cities won't collapse into rubble and tsunamis probably won't sweep through California.
What will really happen when San Andreas unleashes the Big One?
What Will Really Happen When San Andreas Unleashes the Big One? A major earthquake will cause plenty of destruction along the West Coast, but it won’t look like it does in the movies Not a movie still: Fire rages on a flooded street following the 1994 Northridge earthquake in California.

How overdue is California for the big one?
about 80 years overdueCalifornia is about 80 years overdue for “The Big One”, the kind of massive earthquake that periodically rocks California as tectonic plates slide past each other along the 800-mile long San Andreas fault.
What will happen if a mega earthquake hits California?
Landslides could lead to more fatalities and damage. Electricity and sewage could come to a halt along with transportation. Highways, railways, airport runways, and bridges could become unusable for weeks and even months. One of our basic survival needs is access to fresh water, which will be difficult after the quake.
What will happen if the San Andreas fault erupts?
If a large earthquake ruptures the San Andreas fault, the death toll could approach 2,000, and the shaking could lead to damage in every city in Southern California — from Palm Springs to San Luis Obispo, seismologist Lucy Jones has said.
Can California fall into the ocean?
No, California is not going to fall into the ocean. California is firmly planted on the top of the earth's crust in a location where it spans two tectonic plates.
Is a 10.0 earthquake possible?
No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs.

Without functioning infrastructure, the local economy could easily collapse, and people would abandon Los Angeles.
What fault did the San Andreas earthquake break?
Smaller fires merge into larger ones, taking out whole sections of Los Angeles. The lines that bring water, electricity and gas to Los Angeles all cross the San Andreas fault—they break during the quake and won’t be fixed for months.
Why is San Andreas so dangerous?
The San Andreas is the most worrisome, because it generates the quakes that are really dangerous to California residents, Jordan notes. The northern San Andreas leveled San Francisco in 1906, but it’s been a lot longer since the southern part of the fault ruptured. On average, Southern California has seen big quakes every 110 to 140 years, ...

The Los Angeles aqueduct could be fortified so that it won’t break when the San Andreas ruptures. Power, telecommunications and internet systems could be strengthened or have backup systems to ensure that people would be able to communicate.
What plate is California on?
California sits at the border between two major tectonic plates —the Pacific plate, which is moving northwest, and the North American plate, which is sliding past it to the southeast. The two plates don’t just meet at a single line, and the state is crisscrossed with dozens of earthquake faults. The San Andreas is the most worrisome, ...
Why is the Big One so bad?
The Big One is worrisome for the government because it disrupts a large area. But for individuals, the moderate-size earthquakes that are right under our feet are often the worst threat. Los Angeles, for example is filled with faults, and many of them could have a magnitude seven earthquake.
What happens if the San Andreas fault breaks?
The San Andreas extends into Mexico. If the fault breaks there of course the country would feel a tremendous impact. But in the U.S., most of the buildings will do okay. It's more the damage to the infrastructure and getting started again that's the problem.
What magnitude is the San Andreas earthquake?
Getty Images. If you live in California, you'll know the Big One is coming: a powerful earthquake of up to magnitude eight is headed for the state. Energy has been building up along the San Andreas Fault for more than a century. No-one knows exactly when or where, but that one day that energy will be unleashed.
How much more energy does an earthquake have than a magnitude 7 earthquake?
It's a logarithmic scale, so an eight has about 30 times more energy than a magnitude seven.
How many sections of the San Andreas fault are there?
It breaks and moves 15 ft or so all at once, causing an earthquake. There's three, four, five sections, to this fault—and many other faults running in parallel—but we worry about a Big One striking in the north or in the south of the San Andreas. There's a part between north and south in central California that seems act like a buffer.
What does it mean to make sure you are prepared for an earthquake?
It means making sure their water heater is strapped to the wall so it doesn't fall out and break the gas line. It means a little bit of planning.

How many miles away would a Garlock earthquake occur?
Due to the connection between the Garlock Fault and the San Andreas Fault, the study suggests a 50-50 chance that a Garlock quake within 30 miles of the San Andreas would lead to a quake in what’s known as the Mojave segment of the San Andreas’ southern end.
How big is the San Andreas earthquake?
Experts define The Big One as a quake of at least a 7.8 magnitude along the southern part of the San Andreas Fault. That quake would be 44 times stronger than Southern California’s Northridge earthquake of 1994, which caused 72 deaths, about 9,000 injuries and an estimated $25 billion in damage. In 2008, a group of scientists, engineers ...
How many people died in the 2008 earthquake?
In 2008, a group of scientists, engineers and others predicted The Big One would lead to more than 1,800 deaths, 50,000 injuries and $200 billion in damage and other losses. A scientific forecast released in 2014 pegged the likelihood at 48% of at least one California earthquake with a magnitude of 7.5 or more within the following 30 years.
What faults are most likely to cause earthquakes?
Little Faults . As Ross and his colleagues explained, major earthquakes are commonly thought to be triggered by the rupture of one long fault, like the roughly 800-mile San Andreas Fault, and not by a network of faults.
How many faults are there in California?
There are more than 500 known, active faults in our great state of California. But scientists are still discovering ones they didn't know existed. To visualize exactly how many faults lie beneath your feet, think about a bowl of spaghetti. Now take a handful of noodles and throw them on a map. That's about what we’re dealing with here. For a more precise visual, type your address into the map below and see if you're standing above a known fault.

The 7.1 lasted 12 seconds and was felt by about 30 million people. More than 6,000 lost power.
Why is San Francisco called the San Francisco Fire?
Many of those fires will grow and move and converge to make even bigger fires. There’s a good reason San Francisco’s 1906 earthquake is often referred to as the San Francisco Fire. A gas main on fire throws flames into the air after it broke and exploded, destroying nearby homes following the Northridge earthquake.
What is the magnitude of the San Andreas earthquake?
When we refer to "The Big One" we mean a 7.8 magnitude (or higher) quake striking along the southern San Andreas fault. The higher magnitude means it will also last longer than Northridge, but where you are is going to play the largest factor in how this quake feels to you.
