408 earthquakes in list http://earthquake.usgs.gov/earthquakes/recenteqscanv/Quakes/quakes_all.html

To my understanding, that's pretty normal for this area.

Indeed. Also, the numerous earthquakes listed for The Geysers, CA, Anderson Springs, CA, and Cobb, CA are the result of geothermal power plants harvesting steam from ground wells, not from fault lines. They have been a daily occurrence for almost 30 years now. _http://en.wikipedia.org/wiki/The_Geysers

Man made quakes, made similar to fracturing by Halliburton, ( _http://www.youtube.com/watch?v=hM_HB-7cyEI#! ) :shock: and other related company's with the same agenda. While liing of the risk, and consequence's.
Hmmmmmmm, mechanical, not spaced weapon's that can cause similar, and much bigger earthquake activity. It's as if it's like a SG PR diversion tactic, planting the seed's of deception.

Induced Seismicity: Man-Made Earthquakes

Jason (ocean59):
Interesting article I just came across on FB, relating the recent quakes to the Ring of Fire and California:

--- Quote ---Does it seem to you like there has been an unusual amount of seismic activity around the world lately? Well, it isn't just your imagination. The Ring of Fire is roaring to life and that is really bad news for the west coast of the United States. Approximately 90 percent of all earthquakes and approximately 75 percent of all volcanic eruptions occur along the Ring of Fire. Considering the fact that the entire west coast of the United States lies along the Ring of Fire, we should be very concerned that the Ring of Fire is becoming more active. On Wednesday, the most powerful strike-slip earthquake ever recorded happened along the Ring of Fire. If that earthquake had happened in a major U.S. city along the west coast, the city would have been entirely destroyed. Scientists tell us that there is nearly a 100% certainty that the "Big One" will hit California at some point. In recent years we have seen Japan, Chile, Indonesia and New Zealand all get hit by historic earthquakes. It is inevitable that there will be earthquakes of historic importance on the west coast of the United States as well. So far we have been very fortunate, but that good fortune will not last indefinitely.
In a previous article, I showed that earthquakes are becoming more frequent around the globe. In 2001, there were 137 earthquakes of magnitude 6.0 or greater and in 2011 there were 205. The charts and data that I presented in that previous article show a clear upward trend in large global earthquakes over the past decade, and that is why what happened this week is so alarming.
On Wednesday, a magnitude 8.6 earthquake struck off the coast of Indonesia and that was rapidly followed by a magnitude 8.2 earthquake off the coast of Indonesia. Fortunately those gigantic earthquakes did not produce a devastating tsunami, but that doesn't mean that those earthquakes were not immensely powerful.
Normally we only see about one earthquake of magnitude 8.0 or greater per year. The magnitude 8.6 earthquake was the most powerful strike-slip earthquake in recorded history. If that earthquake had happened in the United States, it would have probably been the worst natural disaster in U.S. history.

More California seismic activity after 1st of year: San Diego, San Bernardino, North Bakersfield, Barstow: all are fracture points. Hollister, Palo Alto, Imperial, Ukiah, Eureka, Point Mendocino, Monterrey, Offshore San Luis Obispo, Capistrano, Carmel: these are all stress points of fracture in sequence. "Time" is indefinite. Expect gradual destruction of California economy as people begin mass exodus. Also, Shasta erupts; Lassen activity. Ocean floor begins to subside.

Take a look at Laura's post on the Earthquakes around the world thread. For context of the below post.
--- Quote from: http://www.sott.net/articles/show/244154-Underground-water-in-eastern-Shasta-County-California-mysteriously-disappears ---Stephen Wolf thinks something strange is happening underground in eastern Shasta County and it is draining water wells and maybe even causing sinkholes and subsiding pavement.
A retired marine geologist with the U.S. Geological Survey, Wolf said he has seen what is happening in eastern Shasta County before. After the 1989 Loma Prieta earthquake, water well levels in the area of the quake fell significantly, he said.
Following the 6.9 magnitude quake in the Santa Cruz Mountains, Wolf wrote a paper for the USGS about the effects the quake had on surface and groundwater.
"The correlation is there. The behavior is identical," said Wolf, who has lived in the tiny eastern Shasta County community of Cassel since 2001.
Back in October, 131 earthquakes hit the Lassen Peak area. Most were less than 2.0 in magnitude. But since then the water table has fallen significantly, Wolf said. Pete Amos said his pump had been submerged 40 feet the entire 24 years he has lived in Cassel. But a couple months ago he ran out of water. When the pump company measured his water level, it had fallen to 54 feet, he said.
[...]
Terry Briggs, who owns Gallagher Pump in Fall River Mills, said what is going on in Cassel is unusual. He said the drop in the water table in eastern Shasta County is the most dramatic he has seen in the past 10 to 15 years. "It always moves up and down a little bit, but this was way more," Briggs said.
[...]
Wolf said the seismic activity further fractures the rocky, volcanic soil, allowing the water to flow deeper into the Earth.
Every time a small quake rattles the area around Lassen Peak, his toilet fills with dirty, silted water, he said. That is the silt that is broken loose from the volcanic soil underground, he said.
[...]
Whatever caused the water table to drop, Wolf thinks homeowners in the area should learn a lesson from it and drill their water wells deeper to avoid the problems residents are seeing this year.

We don't know what the cause of X is, but that doesn't matter just do Y. :rolleyes:
--- Quote from: http://www.sott.net/articles/show/244154-Underground-water-in-eastern-Shasta-County-California-mysteriously-disappears ---He thinks the seismic activity also may be related to other soil problems in the area, including a sinkhole that developed March 14 in the side of a holding pond Pacific Gas and Electric Co. uses in a Hat Creek Hydroelectric project in the Cassel area.
Pacific Gas and Electric Co. spokesman Paul Moreno said a sinkhole 3 feet wide and 4 feet deep developed at Hat 1 Forebay this month, so they drained the pond. He said PG&E hired a soil scientist to investigate the cause of the sinkhole, but they have reached no conclusions, Moreno said.
"They don't know what caused the problem. Maybe there's a connection between the water table falling and the sink hole," Wolf said. He said 858 fish had to be rescued and hauled to nearby Cassel Pond. Hat 1 Forebay will remain closed until May, he said.
Sinkholes also have developed at nearby Baum Lake, Moreno said. The Baum Lake sinkholes were caused by underground lava tubes, which are underground tunnels formed by ancient lava flows. Subway Cave, near the intersection of highways 89 and 44 in Hat Creek, is a lava tube big enough to stand up in.

About 30 miles to the west, Paul Schoen is dealing with his own lake problem. He said his 60-acre Arthur Lake has been leaking water out of the bottom for many years. He has hired consultants to find out why the lake is draining. They concluded the volcanic rocks below the surface have cracked and the lake drains from the bottom, said Dennis Possehn, a registered forester Schoen hired to help him solve his lake problem.
"Something's changed over the long term," Possehn said. "In the spring the lake is full, but by the end of the summer all the water is gone."
He did wonder if subsidence discovered in a parking lot in Lassen Volcanic National Park was related to seismic activity in the area.
Ingebritsen hadn't heard about a parking lot, but said there have been some problems found on the road through Lassen National Park. He said the road is hot and soft in the area around The Sulphur Works, in the southwest part of the park.
But he said he didn't think the seismic activity or heat under the road indicated Lassen Peak, an active volcano, was moving toward an eruption.

Now, take a look at this one more time:
