    Today there were 16 significant earth quakes that were recorded by the USGS ranging in the size from M4.5 to M6.1. The total power output of all the quakes that were recorded by the USGS was 77206.52 GJ or 893.59 MW over a 24 h period.


    11 of these quakes were recorded by the RF-Seismograph. For details and a graphical capture of the propagation and explanation see graph below.


    Synopsis: The 30 m and the 20 m band were open enhanced by a meteor that created a noise dome at 00:15 UTC, but 20 m closed down on at the change of the day and only 30 stayed up, until 00:45 UTC. The Bands attenuated as the precursor of the first M6.1 started to close all the bands after 01:00 UTC and the 80 m noise level was aggravated starting at 23:00 UTC on the previous day. There was a brief opening on 40 m just before 02:00 UTC caused by the M2.46 from Hawaii that struck at 02:12 UTC and then a M3.25 from Puerto Rico 6 min after. The opening closed at 02:30 UTC as the M6.1 quake started to again take over the ionosphere and all the quakes at this time were not detected by the RF-Seismograph. As the quake that came from Argentina struck at 03:54 UTC the 40 m band noise started to oscillate, peaking at 04:30 UTC and then again 2 h later. It dropped down with the release of the second M6.1 that struck at 06:48 UTC. The 40 m noise peaked again at 08:15 UTC with the help of the M4.7 from Chile that released at the same time. The aggregation of the ionosphere can also be seen on 30 m that dropped at 03:00 UTC and makes a long noise dome that ends with the M5.0 from New Guinea that struck at 11:49 UTC and brings up 80 m starting at 11:00 UTC. 80 m was enhanced by two quakes from Alaska, after 13:17 UTC. Both were below M3.6 and a M4.4 from Fiji that struck at 13:55 UTC. 80 m attenuated, but 40 m enhanced, with the a set of six quakes, three of them significant and the others below M3.3 but close to the stronger quakes which enhanced their effect on the ionosphere. This set included the M4.5 from Afghanistan at 15:14 UTC, a minor quake from Hawaii 1 min after, the M4.7 from Fiji 14 min after, the M5.3 from the East Pacific Rise, another minor quake from Stanley, Idaho 12 min after and the M3.2 from Denali, Alaska. 30 m and 20 m tried to open up after 15:45 UTC but was very sporadic with the event of six local minor quakes, all blow M4.0. The first two quakes were the M2.9 from Rampart, Alaska at 17:46 UTC that was followed by a M3.9 from Mina, Nevada. These two quakes started to open the 15 m band for about 15 min. The sporadic behavior continues with more minor quakes from Nevada, Puerto Rico and that last one a M2.5 from Denali, Alaska. At 19:30 UTC 30 m opened, but was attenuated by the M4.5 from Turkey that released at 19:53 UTC and a M2.58 from Hawaii 3 min after. 20 m was attenuated also by the M4.7 from Argentina that released at 20:42 UTC. Only 20 m started to boom in after 21:00 UTC until 23:15 UTC enhanced by the M4.9 from Chile at 22:11 UTC and the M4.5 from Indonesia 61 min later. Three more local minor quakes striking after 22:40 UTC, 22:43 UTC and 22:53 UTC, all below M3.0, kept the 20 m band open until 23:15 UTC.

    They were, were they? Funny...lots of DX popping up on 160 and 80 last night...especially South American stations... o_O

    Yup.
    20 meters is dead here.
    Darn Those Earthquakes..
    .
    .
    . Is there a working theory attributing some portion of IONOSOPHERIC HF propagation to seismic/ piezoelectric effects ?

    I thought Vanuatu disappeared beneath the waves decades ago. Rising sea levels and all that.

    So it was nothing to do with the solar sector boundary crossing, or yesterday's major erupting filament (solar prominance) or the minor coronal hole, all of which contributed to an outbreak of aurora. Gotcha.

    Or maybe it was the strong geomagnetic fields hitting earth today that triggered the propagation changes? You are right in that this was not predicted by NOAA (but the shift in interplanetary geomagnetic field polarity was).

    The quakes have far reaching effects.
    • earth quakes cause gravitational waves of dark matter in the local cluster of galaxies
    • the gravitational waves induce synchronized pulsing of the black holes in the center of the galaxies in the local cluster
    • evaporation of matter (alpha particles) in black holes is accelerated during the high pressure portion of the black hole pulses
    • the accelerated alpha particles emitted travel at .002% faster than the speed of light, thus generating worm hole paths where they instantaneously appear in the chromosphere of the sun exactly 48 hours before they were emitted from the source black hole, and thereby mask sunspots and the resultant UV radiation
    • the lack of UV radiation from the sun results in recombination of ionized gasses in the upper atmosphere
    • the de-ionization of the upper atmosphere allows electromagnetic radiation from amateur radio stations transmitting in the HF spectrum to escape into space
    • the excess ham radio radiation in the space surrounding the earth causes excess drag on the rotation of the earth on its axes, thus slowing the rotation of the earth's mantel but not it's molten Nickle/iron core
    • the slipping between the earth's mantel and molten core then causes earth quakes
    • return to the first bullet point above

    So when the bands are dead, it's earthquakes, and when the bands are open, that's also earthquakes. Good to know we have one source for all ionospheric events.
