An earthquake light is an unusual luminous aerial phenomenon that reportedly appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. Once commonly challenged, it was not until photographs were taken during the Matsushiro earthquake swarm in Nagano, Japan (which occurred from 1965 through 1967) that the seismology community acknowledged their occurrence.
In 2001 a satellite discovered that there was a deforming uplift 3 miles (4.8 km) west of the South Sister. There was concern that the mountain was awakening. A map at the Lava Lands Visitor Center of the Newberry National Volcanic Monument south of Bend shows the extent of the uplift, centered a few miles west of the South Sister and reaching a maximum of 11 inches. In 2004 an earthquake swarm occurred with the epicenter in the area of uplift. The hundreds of small earthquakes subsided over several days. As of 2007 the uplift had slowed and concern had diminished though the area was still considered potentially active.

I know...I have been following this with interest. It was my first though (ofcourse). I have also read about fire balls, etc.being associated with quakes.
I am wondering if perhaps the meteorite could be a harbinger. We have been wondering HOW 'they' could know exactly when the quake would occur. What if it correlates with another event? Such as a large meteorite strike?
Just thinking outloud....(have I mentioned that I hate coincidences?)

As far as our quake research goes, I think we are in a holding pattern waiting for more communiques from TM and waiting to see if LA shakes down today.
So let's take a mental break for an hour or two and try to figure out what the hell is going on with these weird light/UFO/meteor reports from SoCal. I have this strange feeling that it really could be earthquake lights... We need to enumerate and corroborate these reports of lights and figure out what they are seeing.
The nearterm prospect of predicting a certain magnitude earthquake on a specific fault, occurring on a particular day or week, is expected to remain out of reach. However, dynamic hazard assessments of individual fault systems at time scales of months appear to be feasible if frequent, high-precision deformation measurements are available.
Although there are diverse geophysical phenomena — electromagnetic and thermal emissions in particular — that appear to bear some relationship to the earthquake c ycle, only surface deformation and seismicity can be directly related to it.
emphasis mine to indicate which particular spot related

t, I remain skeptical. But if there is new data and studies out there discussing the reasons for this increased awareness of a potential big one, please share this with us. Im sure you could U2U someone on this thread that would post this data for us and you.

But the bottom line is, the plates are in motion and heating up. Big ones.....probably everywhere soon as far as I can tell. In fact they already are happening. And all that released pressure is going somewhere else. The tohoku EQs in Japan sent a massive chunk of energy our way via the lithosphere. Both the Cascadia subduction zone (CSZ) and the New Madrid Fault (NMF) have been absorbing energy for 200 to 300 years without really moving. And move they must. Its the law of earth physics.
To advance towards a reliable predictive capability requires that deformation must be resolved at an absolute accuracy of approximately 1 mm/yr over the course of a decade
In the future, the coupling of complex numerical models and orders of magnitude increase in observing power promises to lead to accurate, targeted, shortterm earthquake forecasting
Three decades ago, earthquake prediction was thought to be an achievable goal. Such optimism has all but vanished in the face of current understanding of the complexity of the physics of earthquake fault systems.
6. Are there precursory phenomena (potential field, electromagnetic effects, or thermal field changes) preceding earthquakes that could be resolved from space?
There is a debate as to whether the crust is in a constant state of self-organized criticality in seismic zones, or whether the crust approaches and retreats from that state in a cyclic pattern; the answer has profound implications for the predictability of earthquakes
While predicting the time, location, and size of a particular earthquake will remain elusive, much higher fidelity earthquake forecasts appear within reach
The worst damage occurs in regions of directed seismic energy, and liquefaction (the sudden liquification of permeable sedimentary layers) often amplifies the damage. Very precise surface deformation measurements will help to identify aquifer discharge and recharge, and can provide information on the saturation of vulnerable subsurface sedimentary layers (Tobita et al., 2002). This knowledge can be folded into the earthquake hazard assessments to produce a localized, dynamic measure of seismic risk
Further complicating our understanding of earthquakes is that they do not occur in isolation. Earthquakes located nearby in space and time induce additional forces into a given fault system, either through the static stress changes induced coseismically, or through temporally evolving postseismic stress changes.
Detecting signals precursory to large earthquakes has been one of the most sought after and debated aspects of earthquake physics. Observations of precursory signals have been sporadic and often without a clear link to the subsequent earthquake. In the cases where the connection is clear, the measurements have generally been point location measurements, sometimes requiring measurement sensitivities that are not possible with satellite
I live right on top of the San Andreas in southern Cali.. maybe it's nothing but I've just out of nowhere gotten this sudden intense headache and a bit of nausea with it. May be related to the mexican food I had for dinner but it doesn't usually give me headaches like this. Just don't really feel right and I know some people report major headaches before earthquakes, hope it's not a sign of anything to come personally but just thought I'd mention. Joints are feeling a little bit tense as well, I don't know what's going on. I want to go lay down but now it's got me worried to have this all hit me out of nowhere.

I hate to post and not really contribute anything...but since I find this very interesting, and since I can't subscribe to "HOAX" threads, I'm forced to post here to bookmark this. Sorry to interrupt. Carry on!edit on 14-9-2011 by Wookiep because: (no reason given)
