Today as I'm shure many of you know two earthquakes occured
in the US, one right at the Kansas/New Mexico border with magnitude 5.3, later in the afternoon, (UTC), a 5.8 magnitude in Virginia near Wahington DC! These are magnitudes that I personally have not seen in these areas, but they might occur at _long_ intervals as is known. But what is strikingly apparent is that at this PRECISE instant the worst hurricane since 2008 (which was Ike) is born in the Carribean and is fast approaching the US east coast. Just north of Hispanola at the moment. Name: Irene. If someone were to tell me these three events were not related, I don't know what I would do - probably just laugh?!?? Bjørn Sørheim |

An earthquake, if it is in the same VEI family as a volcano is taking place for the period of time that the weather interferes with the aquifers that cause rupture or are ruptured. That is about all anyone knows about earthquakes and there appears to be only me knowing that, obvious though it seems. How far was the storm in Brussels (at the "precise moment" it went ashore from the epicentres of the US quakes? What exactly causes storms anyway? Contemporary science seems locked into the Richardson thing so badly it has lost track of trying to understand first causes. It would pay dividents in programming the weather computers if only someone a little better at meteorology than I were capable at taking a thorough look at things from the up ground and back arse wads. Still, never mind, eh? Mustn't grumble. |

I once spent some time working as a forecaster in Ancona on the Italian Adriatic. One February, after a ridge of high pressure, an unusually deep depression crossed the Italian peninsular, and just as it did so there was an earthquake at Ancona. I was impressed by the coincidence of timing. I wondered if it was possible that offshore oil-drilling had left the subterranean strata in such a critically unstable state that the slightest fillip â like the lifting of about 5% of the weight of the atmosphere off the surface â could cause a movement. Then I thought, âwhat, through 2 miles of solid rock, I donât think soâ. So I concluded it was most likely coincidence, though Iâm still intrigued by the timing. I had a 98-room hotel all to myself for 4 days, but thatâs another story! Ian Bingham, Inchmarlo, Aberdeenshire. |

A question that comes to mind is how long does it take for the change in the loading on the surface by the atmosphere to propagate down to the depths at which initial earthquake ruptures occur? Also, why does lowered air pressure in the tropical Atlantic trigger earthquakes in Virginia and New Mexico? Shouldn't one expect the earthquake to occur when the hurricane strikes Virginia? -- Stewart Robert Hinsley |

I think you are all looking much too close to home. _Both_ the earthquake and Irene have occurred at exactly the time that the light from the Pinwheel supernova arrived at the Earth. It's obviously the cause of both of them. http://www.sciencedaily.com/releases...0825164936.htm ;-) (just in case) Ian -- The From and ReplyTo addresses are valid |

An interesting thing about earthquakes: the Ancona quake happened about 0500. There were many after-shocks throughout the day, but you get a short warning when one is about to happen. Sound waves travel through the earth faster than shock waves, so about 3 seconds (in this case) before the shock, there is a very low-pitched rumbling sound. When you hear that, you know what's coming. Ian Bingham, Inchmarlo, Aberdeenshire. |

The recent 6+M in Japan was more inteeresting as it was one of the first of that size to occur in the last few months without an anticyclone in the NE North Atlantic.

It remains to be seen just how far apart a set of weather systems need be to increase the potential of an earthquake. What is becvoming clear is that the multiples make a mockery of contemporary magnitude estimates. Failing one cyclone/anticylone, a mag 6 becomes a mag 5 or whatever. But this doesn't mean a Mag 5 is one step less than a mag 6 does it? If you lookat the current and recent lists on the NEIC pages, you will sooner or later notice two or three consecutive quakes of similar magnitude on the list. All within a degree or two of the epicentre of the first. They may be minutes apart or a few hours. These usually tell the end of a large storm. But the storm doesn't have to be a tropical one. Look how a Chilean or Aleutian earthquake occurs when a weather system leaves or arrives in the Virginia / Carolina (N+S) region. Invariably it is a matter of some 80 degrees in that case. But there are other weather systems too, having an associated impact. All that needs be done is to take a look at the weather world wide for a series of such and you have the magnitude point differences. And can come up with inverse square laws for them. (If there is that much difference with distance. They say that swells don't lose their power but whoever "they" are, probably do not take account of the fact that waves are tidal (as are earthquakes.) Look how many mutts on sci.geo.earthquakes still adhere to the principle that harbour waves are not tidal waves.) I am in a state of mind now that I don't get upset by them being stupid. It took a while but when I realised I was knocking on heaven's door I also realised I'd be leaving them all behind. My job is to not step in the dogczjd whilst I am so close to the threshold. (Or not, as the case may be.) |

Interesting observations. Add in gas fracking in the region, and you've got
another "trigger". In 1985, I predicted the Mexican earthquake based on approaching Hurricane Terry. That ended up being a magnitude 8.1. I could see the hurricane tracking across the Pacific Ocean for days, and the path was headed directly for a fracture zone. I believe the hurricane started an underwater landslide that sent a large amount of debris into the fracture and set it off. All it takes is a submersible to prove it later... In the VA case, I believe gas fracking may be more important as a trigger, but add in the weather systems, and other earthquakes that are happening and that put pressure on other faults, then you may have a perfect set-up for these quakes.
