California’s in an exceptional earthquake drought. When will it end?

California is in an earthquake drought.
It has been almost five years since the state experienced its last earthquake of magnitude 6 or stronger — in Napa. Southern California felt its last big quake on Easter Sunday 2010, and that shaker was actually centered across the border, causing the most damage in Mexicali.

Three independent models converge on the high earthquake potential of Los Angeles

Metropolitan Los Angeles is being squeezed from south to north at 8-9 mm/yr (⅓ inch per year), about one-fourth the rate your fingernails grow. This squeeze was the ultimate driving force behind the 1971 San Fernando, 1987 Whittier Narrows and 1994 Northridge earthquakes, three days Angelenos need no reminder of. These tremors were “thrust” earthquakes, in which the top side of the fault is thrust up and over the bottom side – the optimal way to accommodate a tectonic squeeze. The tolls of these earthquakes prompt a natural question.

Damage at the San Fernando Veterans Administration hospital in Sylmar killed 49 people. The VA hospital wasn’t the only hospital damaged. New, supposedly earthquake-resistant buildings at Olive View hospital, also in Sylmar, were destroyed.

The quake also damaged freeways and left older buildings in surrounding cities like Burbank, Glendale and Beverly Hills destroyed beyond repair.

Edge Computing Becomes a Reality

The Edge Data Center market is predicted to top more than $13 billion by 2024; according to a report by Global Market Insights, Inc. The overwhelming demand for edge and cloud computing technology is pushing the market to unforeseen heights. 2019 promises to be an exciting year for WorkSafe Technologies. We believe that the IT industry will be dominated by edge computing and artificial intelligence (AI). As a concept, edge data center development has been deliberated and evaluated for years. We are now at the point where edge computing is becoming a reality as production and implementation of these systems is happening now. Edge infrastructure investments are increasing at a record pace and we should see significant investment in edge data centers over the next 5 years. Where there is a need for more streaming, networking, and storage close to the end user, moving to the edge is the natural answer.
What’s driving the demand for edge computing? The speed of today’s business environment requires fast and smooth access to critical data. Streaming video is expected to account for about 70 percent of all internet traffic and as the video streaming market continues to grow over the next several years, live-streaming video will up that percentage.
Too many important business and consumer decisions are dependent on a real-time flow of information. This means that there is even a lesser tolerance of latency. People want to be constantly connected and then while they are connected to experience instant gratification. Google said that when a website doesn’t load quickly, more than half of visitors will leave the site.
Ultimately when relocating or building an edge data center back to serve the population base, Edge DC’s will need to be built in high to moderate seismic zones. WorkSafe Technologies is here to protect your investment by seismically isolating your critical equipment with ISO-Base™ platforms, or with our new ISO-Dynamic™ heavy-duty isolated raised-access flooring.

The Northridge Quake Struck Twenty-Five Years Ago Today

Twenty-five years ago, just before dawn on Jan. 17, 1994, the Northridge earthquake struck. Those of us who lived it, remember distinctly the chaos of that morning. The quake caused $25 billion in damages and killed dozens.

Northridge was an event that disrupted the lives of people in the Greater San Fernando Valley extensively. The damage was widespread and affected freeways, buildings, and other infrastructure.

Every time an earthquake such as Northridge strikes, we are forced to realize just how unprepared we are.

We know that another quake will strike sometime in the next 30 years. The “Big One” or San Andreas earthquake will unsettle the lives of everyone in Southern California and it might take us years or even decades to fully recover. Think about how different your lives are today from then. Most of us didn’t have cell phones, and the internet was still in its infancy. How dependent are you on the internet? Is your company equipped and ready to operate without it?

That said, to survive a major earthquake, it’s important that you prepare your life and your company to weather the quake. Stock up on water, food, medicine and make sure you have somewhere to go, in-case you cannot stay in your home. It is imperative for all citizens of Los Angeles work out some sort of emergency plan. Then your need to prepare your facility when the “Big One” strikes.

Tips to Protect Your Data Center from an Earthquake

The simple physical nature of data centers puts your organization at risk. Damage from disasters caused by Mother Nature can be particularly destructive to server racks. This is particularly true for earthquakes, so make sure that you follow these tips if you are managing a data center in a seismic region.

AdobeStock_103529624Determine risk. The first step in protection from seismic damage is determining risk. If your facility operates in California or near a fault line, risk will be higher than other data centers. If you are in California, the California Geological Survey has an online tool that will allow you to see whether or not your facility is on a fault line or at risk of liquefaction. It uses USGS seismic data to evaluate your risk.

Consider which floor your data centers are placed on. The location of your data center within your facility can also impact your risk. Data centers on higher floors generally have an increased risk of tipping over, so keep this front of mind.

Install seismic server racks. Installing specialty server racks is a solution to helping mitigate the risk of an earthquake. These cabinets feature augmented bases to keep the rack in place. This method can be costly, so look at alternative methods such as base isolation. WorkSafe Technologies has a variety of products which use base isolation to secure your data center such as ISO-Base™ and the ISO-Dynamic™ flooring system.

Be prepared for all risks from an earthquake. Preparing your data center is vital to seismic risk management. Isolating your server racks is only the first step. Be sure to account for a variety of seismic risks to your data center. Remember to organize your cabling to better prepare for an earthquake. Reducing the risk as much as possible allows you to recover from natural disaster easier.

Inspect your data center and your racks regularly. Stay prepared for the unexpected nature of earthquakes by ensuring your data center is in tip-top shape. Select someone internally to check your entire data center and point out any areas of concern. Adopt solutions to these issues as soon as possible to keep your data center protected.

Preparing your facility for earthquakes is a vital part of running a data center in an area of seismic risk. Data centers are increasing at an impressive rate so make sure to be equipped for the future of your data center.

12 Major Cities Where Your Company’s Data Center is at Risk of an Earthquake – Some may Surprise you

It seems you can’t turn on the television these days without seeing coverage of natural disaster happening somewhere on Earth. Whether it’s a hurricane sweeping through the southern United States, or earthquakes, volcanoes and tsunamis causing mass casualties in a nation along the Pacific Rim of Fire. Although you may live in an area you thought was safe from these kind of natural disasters, you may be surprised at how much actual risk there is. For millions of Americans and thousands of American data centers, the biggest threat may be from the ground shaking below.

Using data from the US Geological Survey, WorkSafe has compiled a list of 12 major American cities which are in serious trouble and have a large probability of experiencing monumental damage from an earthquake. Some of the cities here may not be a surprise to you however plenty here may shock you. The USGS data shows us that some of these cities are at natural risk but some of the risk has been exasperated by mankind’s action. This means that parts of the country which were relatively risk-free are now at an increased risk of a damaging seismic event.

Is your Data Center located in one of the cities listed here? Contact us today to discuss WorkSafe’s variety of solutions to help you through an inevitable seismic event.

Memphis

The USGS says the city is at risk of a serious earthquake.

Most of us generally think a devastating earthquake would be most likely to hit the US in parts of California or Washington, but the threat is very tangible even in the middle America. Take Memphis for example. You might be surprised to learn that Memphis is actually at a significant risk of a seismic event. The USGS believe there is a 25-40% chance of experiencing an earthquake of magnitude 6.0 or greater in the next 30 years.

 

 

San Francisco

Scientists predict the Bay Area is at an elevated risk of a disastrous earthquake occurring soon.

While we’ve seen earthquakes hit this area before, and we are certain to see it again, the bay area has grown exponentially since Loma Preita. Silicon Valley is now home to some of the largest tech companies on earth like Apple, Google, and Facebook, and it is only a matter of time until an earthquake strikes there again. Think about it, when Loma Prieta struck most of us didn’t carry cell phones and social media wasn’t even thought of. What will be the impact to your data center when an earthquake strikes Silicon Valley? And the USGS reports that there is a 63% chance of a large-scale earthquake striking the Bay Area in the near future. The event could even strike on one of the two large faults located in the Bay, the San Andreas and Hayward faults.

 

 

Los Angeles

Residents of Los Angeles have been anxiously anticipating the “big one” to strike for decades. 

LA also sits near the San Andreas fault and for decades, we’ve been hearing about an earthquake striking on this fault. It could even become the source of the “Big One.” The perceived threat even spawned a Hollywood film starring The Rock, where the quake sent Southern California into the sea. While that was a work of fiction, Scientists agree that it is not a matter of “if” but “when.” Experts say a big quake is a near certainty by 2037, and it’ll be a 6.7 or larger. Technology and Media companies with a large presence in Los Angeles include: SpaceX, Netflix, and NBC Universal.

Seattle

The Emerald City is home to some major tech companies as well. Amazon, Microsoft and Nintendo headline the list. Researchers list Seattle as the city that they worry about the most. San Francisco and Los Angeles may have to worry about the well-known San Andreas fault. However, Seattle has to deal with the Cascadia subduction zone and its propensity to unleash a much larger earthquake than the San Andreas is thought to be capable of. It is a nearly 700-mile seismic zone that causes regular earthquakes, and sooner than later Seattle area’s 4 million plus residents will have to deal with a major earthquake.

Oklahoma City

As long as we can remember the idea of an earthquake striking Oklahoma was far-fetched. However, the chances of a large-scale seismic event hitting Oklahoma, including its capital Oklahoma City have dramatically increased. Oklahoma isn’t located near any large fault lines or other typical natural phenomenon that can cause seismic events. Fracking could be at fault as the state has 3 minor quakes hitting on any given day. The “Silicon Prairie” as it is now known is home to a growing technology ecosystem.

 

 

 

Anchorage

Anchorage joins other at-risk cities on this list, including Seattle,  Los Angeles, and San Francisco.

It seems that earthquakes strike Alaska quite often. When they happen, Alaska’s low population density allows for a low number of fatalities, if any. However, if an earthquake were to hit Alaska’s biggest city directly, it could cause some major damage. The city could also be at major risk of a tsunami.

 

 

Tulsa

 

While we have discussed the threat to Oklahoma, we must also mention its second largest city, Tulsa. We would be misleading if we didn’t include it on this list. Residents of Tulsa have become rich as a result of the hydraulic fracturing industry. In turn this influx of money has fueled the Tulsa economy. The growth of the fracking industry has resulted in the USGS planning to issue a new seismic map every year instead of issuing one every six years.

 

 

 

 

Portland, Oregon

Downtown_Portland_Oregon

Portland is also at risk from devastating earthquakes from the Cascadia subduction zone but there’s more.https://blog.worksafetech.com/hs-fs/hubfs/Salt_Lake_City%2C_August_2012_(7707261420).jpg?width=810&name=Salt_Lake_City%2C_August_2012_(7707261420).jpg

The threat isn’t as serious as its Cascadian counterpart, Seattle, but Portland is still at risk. Scientists believe that there is a 20 % chance that Portland and most of northwest Oregon will be hit by an 8.0 quake at some point in the next half-century. They estimate 13 thousand people will lose their lives either in the quake or the resulting tsunami. With tech companies such as Intel, Xerox, and Hewlett-Packard having a major presence there, what will the damage be to the Rose City’s tech sector?

 

 

 

 

 

 

Salt Lake City

Salt_Lake_City,_August_2012_(7707261420)

Salt Lake City actually sits directly on top of the 240-mile-long Wasatch fault.

Utah’s capital of Salt Lake City is actually sitting in peak position for an earthquake. While we don’t know when it will strike, scientists claim that a seismic event with a magnitude as high as a 7.0 on the Richter scale, could occur sometime soon. A big quake hasn’t occurred for some time. The last major instance was in the mid-1850s.

 

 

New York City

nyc-922940_1920

The sheer amount of damage that an earthquake could do to New York City is unthinkable, but it is a possibility

The Big Apple sits on shaky ground. While the city is not at risk of a massive earthquake like Los Angeles or San Francisco, New York is located in an area laden with fault lines. Modest quakes around 5.0 on the Richter scale have hit the area for hundreds of years, the last one of consequence being in 1884. Can you imagine the impact a major quake would have on Wall Street and the resulting effects on the global economy? It is truly frightening to think about.

 

Washington, D.C. (& Northern Virginia)

Monumentul-lui-Washington

In 2011, a smaller 5.8 earthquake centered in Virginia caused damage to the Washington Monument. So, yes, the threat is very real.

The D.C. and surrounding areas should likely become familiar with the Virginia seismic zone because scientists predict it may be the origin of a significant earthquake to come. With the estimation of over 10 million square feet of data centers being built here, and the seismic risk that exists, you had better consider earthquake proofing your facility. As recently as 2011, many buildings in DC and Virginia were damaged by a small earthquake in Virginia. Although this may be minor balanced against the risk in California and the Pacific Northwest, D.C. is still threatened. In fact, there’s higher risk to D.C. than previously thought as geologists have begun to learn more about the encompassing area and buildings there are not being designed to withstand earthquakes.

Charleston

Charleston_South_Carolina-Home_in_downtown_Charleston-20060429163613

You may be the most surprised by the inclusion of Charleston on this list. Charleston is part of the South Carolina coast, and it is better known for its risk of hurricanes coming ashore rather than earthquakes. However, there is an elevated risk for seismic activity. The last quake of note was in 1886 when an earthquake with an estimated magnitude greater than 7.0 struck near Charleston. There was approximately 6 million dollars in quake damage from this quake. When adjusted for inflation, that is north of $150 million in today’s dollars. The data from the USGS show the Savannah risk to be distinct and they anticipate more activity going forward. The USGS predicts the next quake could be greater than a 6.0.

USGS Forecasts 400 Fires, 20,000 People Trapped in Elevators, 400,000 Homeless in East Bay Earthquake.

At 4:18 p.m. today, a M=7.0 earthquake will tear across the East Bay. The quake’s epicenter will be just east of downtown Oakland along the Hayward Fault. Shaking will be felt across the entire Bay Area, and in many areas, it will be strong enough to destroy buildings, and render many vital lifelines useless. Up to 400,000 people will be unable to use their homes, 22,000 people will be trapped in elevators, more than 400 gas and electric fires will start, and East Bay residents could lose tap water for up to 6 months. In total, losses will likely exceed $100 billion, and aftershocks will shake the region for years.

Fortunately, this earthquake is not real, but rather a USGS scenario, dubbed HayWired, that will be presented to the public today, coinciding with the release of the scenario’s second volume, on the impacts of a large magnitude earthquake on the Bay Area.

There Hasn’t Been a Major Earthquake in Northern California in Nearly Thirty Years

At 5:04pm on October 17th, 1989 the Loma Prieta earthquake struck the San Francisco Bay area a few minutes before the Giants were to face the Athletics in game 3 of the World Series. The world has changed a lot since then. From the proliferation of mobile phones, to the growth of email to the launch of Facebook, we’ve become a much more connected society. The virtual explosion of computing power over the past half-decade has been remarkable. New earthquake warning systems are on the horizon for the US. Several companies have even emerged who specialize in mapping earthquake data in real time so that search and rescue teams can improve their disaster response efforts.

There hasn’t been a major earthquake in Northern California in over thirty years. But, ask yourself when was the last major earthquake on the Hayward fault? The answer is about 150 years ago. The 80-mile-long Hayward fault winds through just east of San Jose and then travels underneath the cities of Oakland, Fremont, Hayward and Berkeley. The USGS says a 33% chance exists for the Hayward ruptures in a M=6.7+ earthquake by 2043. All Bay Area residents should be concerned about this prediction.

Seismologists at the Lawrence Livermore National Laboratory recently developed a simulation for an earthquake on the Hayward using three-dimensional technology on one of their supercomputers. This simulation turned into the most advanced ever run.

The LLNL scientists rely on ISO-Base™ platforms from WorkSafe Technologies™ to protect these same supercomputers which ran the simulation because they are located in Livermore which is about 20 miles away from the Hayward fault.

Here is a link to read more about this advanced simulation.

Largest Hayward Fault earthquake since 1981 raises questions about what could happen next

The entire Bay Area was awakened

Last night, at 2:39 a.m. local time, a M=4.4 earthquake struck along the Hayward Fault underneath the city of Berkeley. The quake was felt throughout the entire Bay Area, and by noon today, over 35,000 people had filled out felt reports on the USGS website. Based on the distribution of shaking, nearly 10 million people would have been exposed to some level of shaking. Close to the epicenter shaking was moderate, and no damage is expected. Based on its magnitude, the quake was felt across a much greater area than expected.
