    The M 7.8 event was centred some 800km SW of Sumatera.
    This is the largest event, world wide so far this year

    Time: 2016-03-02 12:49:48 UTC
    Location: 4.908°S 94.275°E
    Depth: 24.0 km

    A tsunami alert was released but cancelled soon after.
    Here is a tectonic summary from the USGS

    this event wiped out my high gain channel of the long period vertical sensor

    more easily readable on the low gain channel of the same sensor

    We don't get too many of these here in Texas. However Oklahoma's been getting a few lately that folks believe come from oil frakking but no one will admit to it.

    The last one I recall was in upstate NY around 1980, I think it was a 2 or 3 on the richter scale just a little shake. At first I thought it was the building but then heard about it on the radio. Shook up a lot of people who never felt one before.

    I remember on the news back in 2004, the dreadful Boxing Day earthquake that took so many lives.

    This is a concern: http://www.stuff.co.nz/world/asia/7...tsunami-warning-buoys-down-when-big-quake-hit

    Also from this article:
    This is ridiculous. But sadly unsurprising.
