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.
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.

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.
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.
Nobody knows when “The Big One” is going to hit California, but here’s how experts think it will play out when it does.
California is the land of beaches, mountains, and Hollywood. It’s also, inconveniently, a dangerous minefield riddled with nasty fault lines that rupture without much warning, generating massive earthquakes that can level buildings, pulverize roads, and kill lots of people in the span of seconds.
The San Andreas is the most notorious of these faults. It runs roughly 800 miles long and produces quakes so catastrophic that there’s a 2015 action movie about it starring The Rock.
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.
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.
Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earth’s rotation could trigger intense seismic activity, particularly in heavily populated tropical regions.
America’s most famous fault line, the San Andreas, is known for its frequent earthquakes, but one part of the system, the San Jacinto Fault zone, in inland Southern California, has been surprisingly quiet for the last 200 years. Now new research has detected small tremors deep under the fault system, suggesting it’s not as calm as we once thought and may be ready to release a massive earthquake sometime soon.
The San Jacinto Fault zone in Southern California is not actually a plate boundary but rather serves as the stress release point between the North American Plate and the Pacific Plate as they grind together at the San Andreas Fault. An area of the San Jacinto Fault zone, known as the Anza Gap, is the main focus of the recent study.
