Residents alarmed: New Zealand shaken by dozens of earthquakes in 24 hour period July 19, 2013 – WELLINGTON, NZ – A 4.3 quake hit the east coast of New Zealand tonight, following a 4.5 magnitude quake in central New Zealand this afternoon, and a 5.7 earthquake that rattled people in Wellington and Blenheim this morning. Geonet reported tonight’s quake was 20 km east of Te Araroa, a settlement on the east coast of the north island, near the southern edge of the Bay of Plenty. The quake was 62 km deep and hit at 11.42pm. GeoNet reported this afternoon’s was of a “strong” intensity, 35 km east of Seddon, at a depth of 15 km. The quake hit at 3.21pm. The first quake struck at 9.06 am and was centered 30km east of Seddon, south of Blenheim, at a depth of 8 km. Rated as severe, it turned Wellington office workers white-knuckled as it swayed high-rises in the capital, with buildings also being rocked in Blenheim. The shallow tremor was felt as far away as Christchurch and New Plymouth. In Wellington it was felt as one jolt, gradually picking up in intensity, while those in Blenheim felt two shakes. GeoNet said it received more than 6000 reports after the jolt. It said the fact it struck off the South Island spared the region from its full force, though there were a few reports that it had a damaging intensity. Though it had knocked goods off shelves in Blenheim it was much too small to cause a tsunami, GeoNet said. An offshore earthquake needed to be at least magnitude 7.5 for a tsunami to be considered possible. The quake was preceded by a magnitude-2.9 “foreshock” in the same location 6 minutes before the main shock. An Earthqake Commission spokeswoman said 14 claims had been received following the first quake, but she expected more once people got home from work. By 11am there had been 17 aftershocks in the region, the largest a magnitude 3.7, 30km east of Seddon. Aftershocks were likely to continue for the next 24 hours. Early analysis had the fault movement as “reverse faulting,” meaning each side of the fault was being compressed. In Marlborough, Lake Grassmere farmer Peter Davison said he had never seen his house buck and shake so much. “It was like being on a bloody rollercoaster,” he said. He was looking out the window of his Marfells Beach Rd home when it hit. It was worse than the Boxing Day quake in 2010, which he had been in Christchurch for, he said. “I’ve never felt anything like it,” he said. His fishing rods had fallen and lay scattered around his library and pictures were askew on the walls. “It’s a wooden house and I’ve never seen the walls move like this,” he said. –Stuff NZ

Powerful 6.5 magnitude earthquake strikes Cook Strait, New Zealand July 21, 2013 – WELLINGTON, NZ - A 6.9-magnitude earthquake has struck New Zealand, rattling the capital Wellington and some other cities. The quake was later downgraded to a 6.5 by the USGS. The quake on Sunday hit 57km southwest of Wellington at a depth of 10.1km, the US Geological Survey said. There were no immediate reports of major damage and injuries after the earthquake but some water mains were broken, windows smashed and power lines downed. Wellington police inspector Marty Parker said there had been minor structural damage that had left parts of the city without power. No tsunami alert was issued. New Zealand’s GeoNet earthquake monitoring service described the 6.9 tremor which was felt widely as severe. “There was a rocking and rattling which lasted about 30 seconds,” a resident in the resort town of Nelson told the AFP news agency. It tremor was followed minutes later by another quake with a magnitude of 5.5 and came about 10 hours after a 5.8 tremor in the same region, which has been hit by multiple quakes in recent days. Recent quakes have been centered about 200km north of New Zealand’s second largest city Christchurch, where a 6.3-magnitude quake in February 2011 toppled buildings onto lunchtime crowds, leaving 185 people dead. The country sits on the so-called “Ring of Fire,” the boundary of the Australian and Pacific tectonic plates, and experiences up to 15,000 tremors a year. – Al Jazeera
