    Pretty scary for all those that were caught up in the Christchurch earthquakes, and last November's Kaikoura quakes.

    A number of smaller ones, as well -- http://www.geonet.org.nz/quakes/felt

    hi guys

    these latest 2 respectable events, a M 4.7 and a M 5.2 are part of the ongoing aftershock sequence of the November M 7.8 event.

    as commented in the reports, both events would have been strongly felt in the epicentral region.

    here's the Kaikoura seismic recorder for the last 24 hrs
    Kaikoura is around 75 km NE of the events
    Christchurch is around 77 km SSW of the events

    The M 4.7 is on the right edge and the M 5.2 lower centre
    as can also be seen, the region is still very active with several dozen aftershocks a day

    There may be minor damage, but nothing significant to warrant a news article (at least, so far).

    Ah I see.
