    hi guys and gals
    latest reasonable event recorded on my system
    2014-09-25 0913.50UT Mw 6.0, offshore, 160km SSW of Gizo, Solomon Islands

    140925 0913UT M6.0 offshr SW Solomons zhi.gif


    Not the largest event in the last 24 Hrs. it was followed by a Mw 6.2, 94km WNW of Willow, Alaska at 1751UT. but because of its depth and distance, it doesn't show up well ... see the small set of surface waves between ~ 1830 and 1859UT

    cheers
    Dave

    Hi Dave, what distance are you from the quake? What body wave phases can you identify? Which component is this, vertical?

    Hi Billiards :)

    2815 km +- ~ 10 km, P and S easily identifiable ( will label and re-upload the image) Yes this is vertical

    140925 0913UT M6.0 offshr SW Solomons zhia.GIF

    just a quick "back of envelope" calculation

    P velocity ~ 7.5 km / sec for 2800 km = 6.22 minutes

    Quake origin time 0913.50UT P arrival time ~ 0918UT ( I haven't done analysis yet so just going by the view on seismogram) P travel time 4 - 5 minutes

    that's not too far out ;)


    cheers
    Dave
