    Hi Jon.

    This is not a common event in this area, where there is a triple junction as two active rift zones meet a seismically active transform zone?

    Could the seismic activity be caused by the power stations?

    Is this seismic activity a cause for concern?

    • This is common in this area. Its just been a while since this part of this area had an earthquake. Last one was in 2000 during the earthquake in SISZ (Magnitude 6,5 and 6.3).

    The US GS is reporting this one
    Sunday 30.12.2018 06:48:28 AM 57.062  34.001 10.0 km 4.9 Reykjanes Ridge

    Maybe this is all rifting actions?
