    Hi Everybody;

    The RF-Seismograph picked up the M7.1 earthquake from Searles Valley, CA. USGS recorded the quake at 2019-07-06 03:19 UTC at a depth of 17 km. Distance between the monitoring station in Vancouver, BC and the epicenter of the quake is 2000 km.

    If you want to receive these earthquakes reports on a regular bases please join the MDSR.io group.

    Here is the location: the graphic below shows that all quakes are concentrated in the valley center. As the ground water drops the stress of the ground increases until it collapses downward.

    The measurement of the RF-Seismograph: The noise level on 80 m (red) increased 15 h before the release or the quake. 40 m (grn) and the 30 m (yel) attenuated before the quake and then amplified 1 h before. 20 m (mag) was aampified2 h before the quake and the attenuated. There were several sharp rises and drops on 15 (blue) and 10 m (salmon). As of the time of this report the 40 m to 20 m bands are still attenuated.

    A quick glossary of how to read the graph below.

    All the best and 73;

    It looks like RF causes the Earthquakes, Not the other way around. :rolleyes:

    Sigh.
    Now you are an geophysics expert too? You are stating the cause of the quakes. Of course the earthquakes are centered on the valley; That is where the fault line lays. shakes head.

    How about quakes centered on the ocean floor?

    The seafloor has a lot of pressure, so there will not be any cavers or openings. Also, the high pressure will compress the soil and slowly turning it into rock! A.

    Any 80M disruption as a pre-cursor?

    Troposcatter on 40m you say?

    200 to 300 miles?

    That means shorter distances also, as there is no "skip zone" with tropo.

    So your claim is 40 meters is reliable 24/7 at distances between zero and 300 miles?

    You can't possibly be serious.

    A quick search shows that electromagnetic signals (primarily magnetic field) from earthquakes have been measured on the order of 1 nT which is over 100000 times weaker than the earth’s magnetic field. What you show in the drawing cannot possibly happen.

    Also, the USGS states on their website:

    “Electromagnetic variations have been observed after earthquakes, but despite decades of work, there is no convincing evidence of electromagnetic precursors to earthquakes. It is worth acknowledging that geophysicists would actually love to demonstrate the reality of such precursors, especially if they could be used for reliably predicting earthquakes!”

    This makes no sense and completely avoids answering the question. So, I conclude that you have no criteria at all with which to quantify changes in the noise floor or anything else about the ionosphere.

    Maybe the blackouts are simply due to many ham stations losing their electrical power as a result of the earthquake.

    I had the same idea, but the quakes are in a really remote area and the power is mostly unaffected.

    this is a theory and may , or may not be accurate, dispute not his words, but dispute his evidence , if you can. He presents an item that he has recorded, now analyse that to correct possible errors.
    even Hertz had disputers.

    He doesn't have evidence. He has raw data from which he draws wild conclusions. We have repeatedly given detailed actions needed to begin a scientific analysis yet are rebuffed with conjecture and anecdotal hypothesis.

    Unfortunately DXW is an over-enthusiastic amateur without mathematical or scientific training who thinks looking at squiggles and time stamps constitutes valid analysis. He is very mistaken, yet cannot understand this.

    Finally a it is DXW's baby. Why should any of us spend several hundred hours needed to begin even a minimal correlation survey? DXW is clearly in crackpot territory. Please stop pandering to his obsession.

    Having one's claims disputed doth not substantiate one's claims.

    The USGS even measures ground water on real time bases. All the areas that experienced the quake are shown in red which means low.
