WELLINGTON, Aug. 16 (Xinhua) -- A series of very strong earthquakes continue to shake central New Zealand with at least eight tremors rated as "severe" in intensity and three rated as " strong" in the less than an hour Friday.
The first quake struck at 2:31 p.m. local time and was centered 10 km southeast of Seddon, in the far north of the South Island, at a depth of 8 km, according to the government's GeoNet monitoring service.
It was a magnitude 6.2 quake and rated in intensity as severe.
A magnitude 5.6 severe quake struck at 2:37 p.m. and was centered 5 km southeast of Seddon at a depth of 5 km.
A strong 4.2-magnitude quake struck at 2:41 p.m., centered 35 km northeast of Seddon at a depth of 5 km.
Six more severe quakes of measuring from magnitude 4.9 to magnitude 5.8 and two strong tremors, both measuring magnitude 4.5, followed over the next 20 minutes.
No injuries have yet been reported, although a house is reported to have collapsed near Seddon.
Wellington has reportedly lost cellphone coverage and the city' s rail services have been halted.
Two large earthquakes measuring 6.5 and 5.5 centered in the same vicinity struck on July 21, closing down parts of central Wellington for at least two days afterwards as engineers assessed buildings for damage.
