Could Electron Counts Detect Major Earthquakes?

hcs_$reboot writes "According to a Japanese researcher, the electron count escalation high in the atmosphere could indicate that a major earthquake is going to happen within 30~40 minutes. That phenomenon was observed before three earthquakes since 2004. If confirmed, the earthquake detection system could save thousands of lives."

    I have never been in an earthquake, but I have been in numerous tornadoes. Back in the 60's we did not have alarms. Now that we have them, it is useful to be woken at night to head down. The tornado warnings HAS saved a number of lives. I can only imagine that the same would be true of Earthquakes.

      You definitely don't want to do this since a brick wall or piece of concrete falling from the ceiling would make short work of your table and, well, you. Having been in numerous earthquakes in my region, the best "anti-earthquake" measure isn't predicting when it will happen (you can't be 100% sure) but strong and well-built buildings / houses. The Japanese have had earthquakes above 7 in Richter scale (that's big) for decades but you won't see any disaster in the scale of Haiti in 2010 or even Turkey and Greece at the late '90s where buildings collapsed in seconds.

      Yeah... the phrase to google for is "high latitude GPS coverage". Its remarkably poor over the north pole, for example. Oh good enough to use, but commercial grade RX are optimized for plenty of overhead coverage and there is zero overhead coverage at all at the pole, and some commercial RX freak out because they see like 20 low elevation satellites and can't decide which to use, so their precision goes bonkers at the pole. Still better than the alternatives, but not as good as low altitude.

      There are differences between military and civilian RX, and its not just temperature ratings and cost. (also non-military rx have to shut down at ICBM altitudes and at artillery speeds, or they are classed as regulated export controlled munition devices)

    Well, for earthquakes near major infrastructure like, say, nuclear reactor, they could initiate a reactor shutdown before the earthquake starts. In places like California with the double-decker freeways, you may be able to get motorists at least off the bridges onto more solid land. You could have trains come to a halt, too. And, you could get emergency personnel paged and at the ready.

    Before the SCADA control system drops due to destruction, you can slam all natural gas valves shut. Well, at half an hour, you could darn near depressurize the system... Instantly, no deaths due to fire.

    Also its practically impossible to be crushed under a building by an earthquake, if you're outside and "far away" from buildings. Yet another reason it sucks to live in an urban area, but for the rest of us...

    Finally its difficult to be crushed under a bridge or trapped in a subway tunnel if they've been evacuated...

    I would hazard a guess that you could reduce fatalities by about 75% to 90% with this system... until false alarms make it ignored, etc.

    I have heard the theories about injecting saltwater into natural gas wells causing minor earthquakes, and the fact that there are no recorded earthquakes form the Marianas trench region, supposedly due to the large amount talc rich mud that acts as a lubricant between the plates. Both of those make sense to me, and that is pretty much the limit of my 'expertise' in plate tectonics; The only way that I could see it being possible is if, somehow they were able to create waves in the magma, and peak the stress near a fault line. It seems to me that it would be far too difficult with our present technology to do. I think it would be very difficult to even create a focused enough broadcast from HAARP to target a specific geographic area. The only way I could see doing this would be with standing waves causing constructive interference only over the target, of which I don't think the array is capable of producing a wide enough range of frequencies (based solely on the antennas' size) The only way I could see them coupling would be through the Earth's magnetic field, and since no one has noticed fluctuations of that in regard to earthquakes, and that the Earth's magnetic field is so weak to begin with, though it is over such a massive area... Also I don't know that EM energy on the Gigawatt scale would be enough to trigger such a massive earthquake, I couldn't rule it out, but I know of no experiments that dealt with it. I think it would be too difficult to do, even assuming HAARP has that effect in the first place. Let alone the list of targets, what would the government gain from it? If anything I would think they would have been opposed to it just because of the negative publicity that GE, and the Japanese government received over it. I don't think they would want to see a military contractor's reputation harmed in such a way, lol!

    Not to be overly cynical but 30-40 minutes to brace for a major earthquake?

    Are you kidding? That's enough time to save perhaps 9 out of 10 people in an earthquake. It's more than enough time to evacuate all but the largest buildings. It's more than enough time to get people away from bodies of water and the possibility of tsunami. You can clear bridges and underpasses, anywhere that has an elevated chance of killing people. It's enough time to shut down gas mains and operating tables. You don't need to get people out of the city, you just need to get them out of the more dangerous situations. And just shutting down utilities would greatly reduce the risk of fires.

    The problem as I see is a high false positive rate. If there are a lot of false alarms, then people won't respond to a real danger.

    However, since you can't exactly evacuate a major city in that time - could a "earthquake shelter" be created?

    Middle of a parking lot away from buildings, for example, would be an adequate earthquake shelter. In a dense city, I'd recommend packing people into "green spaces" and other open places away from buildings. Subways and other underground structures shouldn't be too bad either. They are. all else being equal, somewhat more resistant to earthquakes than surface buildings.
