A spate of strong earthquakes have struck the central South Island this morning.
Four quakes measuring between 6.4 and 4.1 in magnitude hit the Methven and Arthur's Pass area between 6.48am and 6.59am.
The first tremor, measuring 6.4, struck 35km north of Methven at 6.48am, GNS Science reported.

A southern police communications spokesman said they had not received any reports of damage.
Four minutes later at 6.52am, a second quake measuring 4.1 in magnitude rocked the region.
It was centred 30km west of Arthur's Pass and was 5km deep.
GNS classified the quake as strong.
At 6.58 a third quake, measuring 4.1 hit the same spot, GNS said.
It was 5km deep.
Then, a minute later at 6.59am, another strong quake hit the same location, measuring 4.2 in magnitude. It was also shallow, centred 5km deep.
Comment: SOTT has been following the sinkhole phenomenon since the early 2000s. It was once a rare occurrence and is now a part of our 'normal' daily lives.
This 'sinkhole' phenomenon cannot be explained satisfactorily by old water mains breaking, the dissolution of underground rock or depleted aquifers. Very often the bedrock in locations hit with sinkholes was NOT water-soluble.
We suspect that the global increase in gaping sinkholes is the result of larger solar and seismic phenomena which cause Earth to 'open up' due to a weakened surface-core electric field. See Volcanoes are erupting all over the place right now. Scientists have figured out why: A minute slowdown in the planet's rotation for a recent article about a slowdown in the planet's rotation being at least partly responsible for increased volcanic activity.
