Earthquake at 01:36 UT

Once again the spectre of space weather correlation with earthquakes turns up.

This was a shallow earthquake causing significant damage, >20 deaths reported so far. Rescue teams are assembling. People trapped under collapsed structures.

A large number of aftershocks have occurred, mostly much deeper than the main ‘quake.

    Hours later, a similar sized quake has hit Myanmar. Condolences to all affected.

    From suggestion 20 earlier:
    Italy’s knee-jerk reaction??

    Soon Etna may have something to say, let’s see.

    Thanks Tim for putting a message out about this quake. I was in the middle of my research documenting of earlier earthquakes when the Italian quakes started coming in. It is hard to see this devastation happening and can do little but pray for those who survive. Soon, perhaps, we can get enough support to get a real-time tracking model to help show folks where the greatest threats are at on an hourly basis and build from there.

    Yup, as I said;
    “Prediction of volcano and earthquake activity is the holy grail. The social and economic risks and consequences are huge”.
    We should be devoting significant resources to reducing the risks and warning of these events. Surely with our tools, technology and experience we can do better.
    I spent some time near this area. Wonderful people and places. I can imagine the horror. My thoughts and prayers are with them.

  5. See time …
    Jump solar wind and 22-08-2016 lunar apogee

    It’s a complex electrical circuit !

    The link I give above may provide better visualistion of what is happening. Africa is pushing into Europe and the subduction zone is under Sicily. These last two weeks there was activity further down. Every so often Italy has to bend its knee.

  7. crosspatch says:

    On average there is an M6 quake somewhere in the world every three days so the chances of such a thing happening when there is a strong flow from a coronal hole (solar activity is actually pretty low right now, this activity due to solar wind pouring out of a coronal hole). An average year has over 130 M6-M6.9 events so the probability of one happening on a day when we are in a stream of solar wind from a coronal hole is pretty good. Nothing to see.

    Now is the following morning. The death toll has reached 250, final will be rather greater.

    The area is beautiful if too hot for many at this time of the year. Tragedy, grief, visits the region again.


    A method for the determination of lunar and solar daily components of earthquakes is proposed. Its application to the most intense earthquakes with epicentres in Italy (from 1900 to 1983) provides for the first time large and significant lunar and solar tidal terms. The absence of significant results from the analysis of 9157 world-wide large shocks processed according to the proposed method and to routine spherical harmonic techniques indicates that the Italian earthquakes are locally tidally triggered.

  10. tchannon says:

    That’s much my thoughts on the matter crosspatch but neither am I dismissing the unknown. Rock fails when stress has built up, never exactly the same place twice. In this case Italy is a mass of candidate fail points. Trying to predict when one of these fails is ongoing in the Italian academic world. Saying anything is risky given a peculiar legal system.

    Italy Earthquake: Complex Geology Drives Frequent Shaking

    ‘…because the continental plate collision zone is drifting southeast, it is stretching the crust beneath a region of the Mediterranean Sea. This ground extension, which occurs at a 90-degree angle relative to the mountain range, is what was behind both the current earthquake and the 2009 L’Aquila temblor’
