Okay, Los Angeles, it's time you take a moment and think a few things about: What to do today so you're better prepared when it  really happens here.
All these earthquakes you've noticed in the last few days? Of course. Rocking, the rolling pool sloshing ̵
For now we are okay. The long rolling motion may have freaked you out, but if you live close to L.A. It probably didn't do any harm.

Despite the fact that Los Angeles Times reported that several things fell from the walls of Crate and Barrel's location in The Grove. But freeway flyovers stand to endure another day's commute. The aqueduct remains uninterrupted. Midnight yachts remain optimistic over their carports.
At some point, probably faster than later, this will not be the case. The pictures from Ridgecrest and Trona show a little bit of what might – what will a day happen here. Where 25,000 people live in Ridgecrest, there are over 20 million in Greater Los Angeles, Inland Empire and San Diego.
Friday evening 7.1 shaker classified as a "big" earthquake by US Geological Survey (USGS) standards. It was the second of two major earthquakes that hit this week in the Mojave Desert, and the largest in Southern California for about 20 years.
The day before an earthquake of 6.4 magnets hit at 10:30 in the morning of July 4. We now know that it was a cold for the larger earthquake – some seismologists like Dr. Lucy Jones had warned that we could happen.
Even now, seismologists emphasize that there is still a small chance that another potentially larger earthquake on the same error system could still occur.

All earthquakes have emerged about 125 miles north of Downtown Los Angeles. At that distance, shockwaves dampen enough, so there is virtually no significant damage beyond a rattled sense of security.
At the same time, a 7.1 releases about four times the energy of a 6.7, the strength of the Northridge earthquake from 1994, killing 57, and constituting approx. $ 35 billion in damage .
Countless local errors can generate earthquakes as large as (and in some cases larger) than those in Mojave over the last few days. The known flaws cross southern California as spaghetti with known names like Newport-Inglewood Hollywood Raymond and Puente Hills  error.
Everyone runs under one of the most densely populated metropolitan areas of the country – meaning a major earthquake on any of them would be a major disaster. Then there is the local father – the San Andreas error, which theoretically can generate a 8.2 . An earthquake of this scale would release about 45 times more energy than Friday's 7.1 and about 180 times more energy than Northridge. Close by is San Andreas within 40 miles of Downtown Los Angeles and cliffs through the towns of Palmdale and San Bernardino.
The earthquake, a great earthquake in San Andreas, is the most worrying option. Scientists evaluate the southern part of the error – the area near Los Angeles – breaks about once every 150 years. The last time it did, it was a January morning 162 years ago, in 1857, when it produced a 7.9 tremor that shook most what we call Los Angeles. It lasted somewhere between one and three minutes.
The difference between an earthquake from San Andreas and a large temblor on any of the other local faults is basically a function of the scale. Where a 7.0 on the Hollywood mistake would do great damage to Metro Los Angeles and the San Fernando Valley, the same cannot be said for South Orange County or Ventura. A 8.0 on San Andreas, on the other hand, would cause bad damage almost anywhere between San Luis Obisbo, Tijuana and the Salton Sea.

That's what people think when they talk about "The Big One." The prospect of an earthquake of this scale is subject to considerable work by journalists, producers and authors at LAist and KPCC. Our 9-part podcast series The Great One: Your Survival Guide was released earlier this year and examines what will happen when San Andreas next slips and what you can do to prepare.
On the one hand These are the things you already know you need to do, but maybe you don't have:
- One gallon of water per. person (and pet) per. day for as many days as you can save (but definitely at least three).
- Non-perishable foods
- Additional meds
- Make sure your apartment building is properly retrofitted or your bolts bolted to its foundation etc.
It also means planning ahead with your loved ones and your neighbors.
Jones, the CalTech seismologist, who has been southern California's all-seismic since the Northridge earthquake, says the preparation of our social infrastructure is as important as our physical infrastructure.
"I want you to talk to someone you care about. Go to your neighbor, go to your church, go to your school and tell us what we can do together?" Jones told us at the end. a Saturday morning interview. "What really matters how we handle a large earthquake in this dense urban area is how well we work with our neighbors."
It means having a plan and actually speaking through in advance with those who are close to you, what to do when the ground stops shaking.
Jones added that any level of shaking serves as a kind of reminder of what can and will eventually happen here.
"That's what must be solid – the ground beneath our feet – moving on us. It's a disturbing experience long before they actually become dangerous to us," she said.
So make your plan. If you are about to go out to the store, a few extra amounts of water will not hurt either.
