Quake cluster recorded in Kermadec area

GeoNet has been monitoring a series of quakes in the Kermadec Trench area.

Ten earthquakes measuring more than magnitude 4.9 have been recorded in the Kermadec region north of New Zealand in the past 24 hours.

The largest was a magnitude 6.4 quake.

GeoNet said it has been monitoring what it calls an active sequence in the region.

The quakes have been largely unfelt and have not posed a threat to New Zealand.

It said the sequence was considered to be heightened activity for the region, and was not uncommon and did not mean there was a bigger quake coming.

"There is an active plate boundary in this region (extending up from the Hikurangi Subduction Zone in [New Zealand] up towards Tonga), that has the potential to cause earthquakes large enough to produce tsunami."

GeoNet warns large earthquakes could occur at any time in seismically-active zones.
