    initial listing is a M 7.1 eastern New Britain, PNG

    this is following the M 6.8 that occurred at that location yesterday

    the 6.8 can be seen near the top of the seismogram and the 7.1 at the bottom

    OK the amplitude isn't as large or as sustained as yesterday's event and the ~ 6km difference in depth wouldn't account for the difference in amplitude between the two events

    I'm expecting the magnitude the probably be revised down to around 6.8 +- 0.2

    the numbers of quakes are no higher than normal. In fact over the last 6 months the numbers have been considerably lower than the average

    I didn't watch that video yet, But I assume it's probably showing the movement of the Indian continent up into the Euro-Asian continent, which has been occurring for 100's of millions of years. That is all just part of plate tectonics

    OK here's the seismogram for last nite's event
    and as suspected it was downgraded from the initial M 7.1 to a M 6.8
