    Biggest possible earthquake

    Is a magnitude 10 possible? 11? 12?

    USGS:
    No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. That is, the longer the fault, the larger the earthquake. A fault is a break in the rocks that make up the Earth's crust, along which rocks on either side have moved past each other. No fault long enough to generate a magnitude 10 earthquake is known to exist, and if it did, it would extend around most of the planet.

    Could an earthquake along the fault involve movement of, say ten meters instead of one? Or a hundred meters?

    Yes, there are big vertical shifts sometimes, along a fault, elevating, for example, salt beds or chalk beds from under sea to way above sea level. Sometimes this is a wrinkle, sometimes along a fault line.

    When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.
