Cascadia Anyone? 5.2 Quake

N_America Cascadia 5.2

N_America Cascadia 5.2

Now we’ve had a modest quake on each side of the Cascadia fault…

I hope this is not a pre-shock…

  1. Perhaps it could be applied in this case the methodology used by Prof.Venkatanathan:
    PLANETARY CONFIGURATION: IMPLICATIONS FOR EARTHQUAKE PREDICTION
    N.Venkatanathan1, N. Rajeswara Rao1, K. K. Sharma1, and P.PeriaKalli1
    1Department of Applied Geology, University of Madras, Guindy Campus, A.C.College Buildings,
    Chennai – 600 025, India.
    Abstract The hazards of earthquakes are avoidable if prediction can be made early, which would enable their mitigation, reduce damage to life and property drastically and facilitate precautionary measures by government and NGOs. This attempt aims at establishing planetary configurations as a definitive means of earthquake prediction. Also this study aims to establish the occurrence of earthquake precursors like fore shocks and change in ground water level with respect to planetary configurations. When two or more than two planets, Sun and Moon are aligned more or less in line (0o or 180o) with the Earth, then the Earth would be caught in the middle of a huge gravity struggle between the Sun and the planets. The gravitational stresses would change the speed of the Earth in its orbit. When the speed of rotation of the earth changes the tectonic plate motion also gets affected.
    The total angular momentum of planets involving in earthquake triggering mechanism can be calculated and the total force acting at the epicenter in the opposite direction to the rotation of the earth can also be determined. The planetary forces acting in the opposite direction to the rotation of earth act as a triggering mechanism for the accumulated stress at faults and plate boundaries, to be released abruptly. This does not, however, mean that earthquakes will occur at all edges of the plate boundaries. In order to trigger an earthquake in one particular place, two conditions should be
    satisfied. They are a) distance of epicenter from the planet position and b) Direction of force acting at
    the possible epicenter. From the analysis of “Significant earthquakes” over past 100 years, it is
    inferred that the latitude, longitude and magnitude of the tremor is related to the distance from the
    planet and direction of planetary forces acting at any particular point. By correlating the planetary
    positions and their forces with geology of that area, earthquakes can be predicted with fair accuracy
    with regard to latitude, longitude and magnitude at least a month before.

  2. Also M.Vukcevik found an interesting correlation with regard to the february 27, 2010, 8.9 Richter big earthquake at Concepcion, Chile:
    http://www.vukcevic.talktalk.net/LFC13.htm
    Which, btw, had been forecasted by Ruegg et Al.:

    The Concepción–Constitución area [35–37◦S] in South Central Chile is very likely a mature seismic gap,
    since no large subduction earthquake has occurred there since 1835.

    No preventive measures were taken.

  3. Geocentric position of Sun, moon and planets during the big Chilean earthquake:

  4. E.M.Smith says:

    It bothers me some that all the OTHER places that had reds and blues are now just showing week old yellow spots in the various maps here:

    https://chiefio.wordpress.com/2010/07/19/quakes-several/

    And now the Cascadia (and a bit up in Alaska) are the blue spots after it’s been dead quite for a year or two of watching it.

    It’s just spooky. Like everywhere else has relieved stress and they are all just waiting for the last spot to go so they can get back to work…

    I’ve just got a bad feeling about this… but I get that way about quakes on full moon times …

  5. @E.M.Smith
    I’ve just got a bad feeling about this… but I get that way about quakes on full moon times
    And with the Sun almost opposite to it.
    See also (in google earth) the line of volcanoes in front of Oregon. We should ask, also, our friend Vukcevic to tell us the GMF variation on this location.
    I doubt the theory of “relieved stresses”, it has to do more with interactions…
