    Prelim report

    8.5 166km WNW of Chichi-shima, Japan 2015-05-30, 11:23:00 UTC, 696.0 km Deep


    At almost 700km, this extremely deep and will result in a significant lack of surface waves

    That's good. Japan doesn't need another tsunami.

    M7.8 - 189km WNW of Chichi-shima, Japan
    2015-05-30 11:23:02 (UTC)
    Lat/Long = 27.831°N 140.493°E
    depth = 677.6 km (421.0 mi)
    Nearby Cities
    1. 189km (117mi) WNW of Chichi-shima, Japan
    2. 771km (479mi) SSE of Shimoda, Japan
    3. 781km (485mi) SSE of Oyama, Japan
    4. 783km (487mi) SE of Shingu, Japan
    5. 874km (543mi) S of Tokyo, Japan
    Very deep means little surface action, or rather the energy is distributed over a larger area of the surface, so a significant tsunami would not be likely.
