If you thought that the earthquake that
struck northern California on Sunday was something, just wait until you see
what is coming in the years ahead. As you will read about below, we live at a
time when earthquake activity is dramatically increasing.
This is especially true of the "Ring of Fire" which runs roughly along the outer perimeter of the Pacific Ocean. Approximately 81% of all big earthquakes occur along the Ring of Fire, and the entire west coast of the United States falls within the danger zone. Over the past few years, we have seen huge earthquake after huge earthquake strike various areas along the Ring of Fire, but up until now the California coastline has mostly been spared. However, there are indications that this may be about to change in a big way.
Early on Sunday, a 6.1 magnitude earthquake struck the heart of wine country. It was the largest earthquake to hit northern California in 25 years. More than 120 people were injured, scores of buildings were damaged and Governor Jerry Brown declared a state of emergency.
It is being projected that the economic loss from this earthquake will exceed a billion dollars. Since the initial quake, there have been more than 60 aftershocks, and residents are very much hoping that the worst is over.

The damage in Napa is "fairly
significant," said Glenn Pomeroy, the CEO of the California Earthquake
Authority, who surveyed the area Sunday afternoon.
"The downtown area is hardest hit, probably because of the age of construction down there," Pomeroy said. In the residential areas, he is "seeing a lot of chimneys that've come crashing down."
That sounds pretty bad, right?
But remember, this was only a 6.1 magnitude earthquake. As Wikipedia explains, a 7.0 magnitude earthquake would be many times more powerful...
The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.
As measured with a seismometer, an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times greater than that of an earthquake that registered 4.0, and thus corresponds to a release of energy 31.6 times greater than that released by the lesser earthquake.
And the earthquake that happened on Sunday would not even be worth comparing to an 8.0 or a 9.0 quake. In fact, one study concluded that a 9.0 magnitude earthquake along the Cascadia fault could potentially produce a giant tsunami that would "wash away coastal towns"…
If a 9.0 earthquake were to strike along California’s sparsely populated North Coast, it would have a catastrophic ripple effect.
A giant tsunami created by the quake would wash away coastal towns, destroy U.S. 101 and cause $70 billion in damage over a large swath of the Pacific coast. More than 100 bridges would be lost, power lines toppled and coastal towns isolated. Residents would have as few as 15 minutes notice to flee to higher ground, and as many as 10,000 would perish.
Scientists last year published this grim scenario for a massive rupture along the Cascadia fault system, which runs 700 miles off shore from Northern California to Vancouver Island.
And when we think about "the Big One" hitting California, most of the time we think about southern California. The most famous fault line in southern California is the San Andreas fault, but the truth is that many experts are far more concerned about the Puente Hills fault line. According to one seismologist, that is the fault that would be most likely to "eat L.A." and cause hundreds of billions of dollars in economic damage...
Video simulations of a rupture on the Puente Hills fault system show how energy from a quake could erupt and be funneled toward L.A.'s densest neighborhoods, with the strongest waves rippling to the west and south across the Los Angeles Basin.
According to estimates by the USGS and Southern California Earthquake Center, a massive quake on the Puente Hills fault could kill from 3,000 to 18,000 people and cause up to $250 billion in damage. Under this worst-case scenario, people in as many as three-quarters of a million households would be left homeless.
So don't get too excited about what happened on Sunday. Scientists assure us that it is only a matter of time before "the Big One" hits California.
In fact, the 6.1 magnitude earthquake that hit northern California on Sunday was not even the largest earthquake along the Ring of Fire this weekend. According to the U.S. Geological Survey, a 6.4 magnitude earthquake shook the area around Valparaiso, Chile on Saturday and a 6.9 magnitude earthquake struck Peru on Sunday.
As I mentioned above, we have moved into a time when seismic activity is steadily rising. It has gotten to the point where even the mainstream media cannot ignore it anymore. For example, just check out the following excerpt from a recent CBS News report…
The average rate of big earthquakes — those larger than magnitude 7 — has been 10 per year since 1979, the study reports. That rate rose to 12.5 per year starting in 1992, and then jumped to 16.7 per year starting in 2010 — a 65 percent increase compared to the rate since 1979. This increase accelerated in the first three months of 2014 to more than double the average since 1979, the researchers report.
Something is happening that scientists don't understand, and that is a little scary.
As I wrote about the other day, earthquake activity seems to particularly be increasing in the United States. While the west has been relatively quiet, the number of earthquakes in the central and eastern portions of the nation has quintupled over the past 30 years…
According to the USGS, the frequency of earthquakes in the central and eastern U.S. has quintupled, to an average of 100 a year during the 2011-2013 period, up from only 20 per year during the 30-year period to 2000.
Most of these quakes were minor, but research published by the USGS earlier this year demonstrated that a relatively minor magnitude 5.0 quake caused by wastewater injection after conventional oil drilling triggered a much bigger, 5.7 magnitude quake in Prague, Okla.
“We know the hazard has increased for small and moderate size earthquakes. We don’t know as well how much the hazard has increased for large earthquakes. Our suspicion is it has but we are working on understanding this,” said William Ellsworth, a scientist with the USGS.
What in the world could be causing this to happen?
Oklahoma, which used to rarely ever have significant earthquakes, has experienced over 2,300 earthquakes so far in 2014.
That is absolutely staggering.
And of course volcanic activity has been rising all over the planet as well. In 2013, the number of eruptions around the globe set a new all-time high, and right now persistent rumbling under Iceland's Bardarbunga volcano has much of Europe on alert...
For more than a week the earth has been rumbling beneath Iceland’s looming Bardarbunga volcano. The almost continuous small earthquakes led the government to activate its National Crisis Coordination Centre this week and block off access to the largely uninhabited region around the Bardarbunga caldera.
Major airlines are making contingency plans for a potential eruption that could throw dust into the atmosphere and disrupt flight paths between North America and Europe.
Some scientists are saying that if that volcano erupts, it "could trigger Britain’s coldest winter ever".
Clearly something is happening.
All over the world seismic activity is on the rise.
That means that the shaking in California (and in much of the rest of the world) may soon get a whole lot worse.
