![]() ![]() He is recognised as an international expert on the performance of concrete structures. Nic Brooke is the coordinator of the ReCast Project and an associate professor at the University of Auckland. In short, those of us who have been involved in the project are confident that the research has produced robust ways to greatly improve building performance in the event of a future major earthquake.Īs the ReCast Floors Project has demonstrated, the future resilience of New Zealand’s built environment can in many instances be achieved through proven and elegant modifications to existing buildings. About 100-150 of these quakes are large enough to be felt the others we only know. on September 4, 2010, when a magnitude 7.0 earthquake. Every year, GNS Science records over 20,000 earthquakes in New Zealand. This research will give them the confidence that retrofitting can work in ways that comply with regulations, and in turn helps offer their tenants peace of mind. Residents of Christchurch, New Zealand, and surrounding communities were rattled awake at 4:35 a.m. Geological Survey said, as the nation grapples with widespread landslides and flooding across. New Zealand lies on the seismically active Ring of Fire, a 40,000-km arc of volcanoes and ocean trenches. A magnitude 5.7 earthquake struck near the New Zealand capital Wellington on Wednesday, the U.S. GeoNet says the quake took place at 7.38pm around 50km northwest of Paraparaumu at a depth of 48km. ![]() Until now, building owners in Wellington, Auckland, and throughout New Zealand have been waiting for verified, tested retrofit methods before going ahead to upgrade their buildings instead of demolishing and sending them to landfill. Magnitude 6.1 quake strikes off New Zealand coast. The quake started with a large jolt followed by at least 30 seconds of moderate shaking. We’ve used it to test and verify the retrofit solutions, which included steel bracing and bolting systems that are fitted underneath the existing flooring.ĭesign guidance was then developed for the different solutions that will enable practising structural engineers to implement them. “Next thing my husband called me from his work in town and told me to get out ASAP and go to higher ground, as this was no drill and they were evacuating the hotel (he works at a hotel right on the waterfront),” she wrote.Nic Brooke is the coordinator of the ReCast Project and an associate professor at The University of Auckland. “Just hearing that sound made me get a bit anxious.”īaker’s home sits 10 meters (32 foot) from the water’s edge. WELLINGTON, New Zealand (AP) One of the strongest earthquakes to hit the South Pacific in modern history triggered tsunami warnings across the ocean and forced thousands of people in New Zealand to evacuate coastal areas Friday. Summary magnitude for GeoNet is then defined as: M (2 MLv + (0.4 numberof stations (Mw (mB)) - 1) Mw (mB)) / (2. “An hour after that, the tsunami siren went off and for a split second I went into panic mode,” Baker added. GeoNet combines magnitudes into a summary magnitude, M, which consists of a weighted average of the individual magnitudes and attempts to be a best possible compromise between all magnitudes for a range of earthquake sizes. Then the first Kermadec quake struck with little warning. When the first alerts came about earthquakes in New Zealand, Baker wasn’t too worried, she wrote to CNN. The 2016 Kaikura earthquake was a magnitude 7. In Russell, New Zealand, Rita Baker told CNN that she had evacuated with other residents to a hill overlooking the Bay of Islands. Map of Kaikura earthquakes USGS ShakeMap for the event. The third and strongest quake struck the Kermadec Islands, a mostly uninhabitated group of islands some 800 km (500 miles) northeast of the North Island, on Friday morning, shortly after a 7.4. He added in his 13 years responding to earthquakes and tsunamis in New Zealand, “this is the first time we’ve had this particular sequence.” The earthquake came “without any significant warning,” seismologist Bill Fry said in a press conference Friday. The epicentres were located southeast of Raoul Island in the Kermadec Islands, part of the New Zealand outlying islands. New Zealand is in a national state of emergency, as Cyclone Gabrielle batters the country, with floods trapping people on roofs, thousands displaced and landslides destroying homes in what. It added that strong currents and unpredictable surges may continue for several hours, and that people should stay away from beaches, shores and rivers. The 2021 Kermadec Islands earthquakes were a series of earthquakes with magnitudes of 8.1 and 7.4 that occurred at 19:28:31 UTC on 4 March 2021. On Friday afternoon, the agency downgraded its warning from a “land and marine threat” to “beach and marine threat,” meaning all residents who evacuated can now return to their homes. New Zealand has had: (M1. ![]()
