To aid this work the University of Auckland has constructed a major new structures test hall on the Newmarket Campus with one of the largest seismic testing walls in Australasia. Researchers at the University are examining ways of minimising loss and damage, and speeding recovery, after major earthquakes. We know from Christchurch that they perform particularly badly in a large earthquake. Among buildings of this type, churches are particularly vulnerable to earthquakes because they are tall structures with large spaces and few or no internal walls. They are found in main streets all over the country and are generally the oldest in any community, the most valuable to the community and the most dangerous in an earthquake. One of the main causes of death and injury in the Christchurch earthquakes was unreinforced masonry buildings. The total cost of the rebuild has been put at over $40 billion and it is estimated that it will take the economy 50 to 100 years to recover completely. Geophysical Research Letters, 2021 48 (24) DOI: 10. Almost all the city’s internationally recognised heritage buildings were lost. Illuminating a Contorted Slab With a Complex Intraslab Rupture Evolution During the 2021 Mw 7.3 East Cape, New Zealand Earthquake. Some 1,240 buildings in the central city, from old to just-built, have had to be demolished. According to preliminary data, the quake was located at a moderately shallow depth of 57.4 km. A corresponding tsunami warning has been issued after the earthquake, it added. A massive earthquake of magnitude 6.1 hit the north west of Wellington, New Zealand on Wednesday. The US Geological Survey (USGS) said that quake was estimated at a depth of 10 km (6.21 miles). 4, 2010, caused severe structural damage in Christchurch, a city of 380,000 that is the largest on New. 185 people from 20 countries were killed. New Zealands Kermadec Islands region has been hit by an earthquake of 7.1 magnitude on Thursday, prompting tsunami warnings. The first of the two earthquakes a decade ago, a magnitude-7.1 convulsion on Sept. ET: This article has been updated to include comment from Yannik Behr.The February 2011 Christchurch earthquake was New Zealand’s second deadliest natural disaster, surpassed only by the 1931 earthquake in Hawke’s Bay. At 12.03am (NZT) on 14 November 2016, Kaikura and North Canterbury experienced a 7.8 magnitude earthquake that had wide reaching impacts on New Zealand North. Earthquakes with a magnitude of over 8.0 destroy numerous houses within a radius of several hundred kilometers and are causing great damage and devastation. More than 20,000 people reported feeling a shake in the areas nearby, including Hamilton, Tauranga, Auckland, and Rotorua. The 5.1 magnitude quake hit at a depth of 7km about 5km south of Te Aroha in the Waikato region at 5.39am. Taupō is likely to erupt at some stage over the next few thousand years.ĭo you have a tip on a science story that Newsweek should be covering? Do you have a question about the Taupō super volcano? Let us know via 3/8/23 3:08 a.m. Earthquakes in New Zealand In New Zealand, there are very strong earthquakes with far-reaching consequences. The northern part of New Zealand has been shaken by a strong earthquake this morning. While some of its past eruptions have been violent and destructive, these are rare. Toka T Ake EQC is a New Zealand crown entity investing in natural disaster research to help communities reduce their risks, and providing home insurance to. Scientists are not concerned about the increased unrest as Taupō is not showing any signs of eruption. Over the past 150 years, there have been 17 previous episodes where Taupō has shown signs of unrest. We also look at other measurements like the movement of land determined from high-resolution GPS to come up with a diagnosis of what may happen within the volcano."Īlthough there has been heightened activity around the volcano, it is not the first time it has happened. "That is why we are more focused on the changes in the number and location of earthquakes over time. "There are many active faults beneath Lake Taupō and earthquakes can be caused by the movement of tectonic plates, volcanic fluids, and often a combination of the two. "It is very difficult to say for one earthquake what caused it," Behr said. The quake was at a depth of 152 km (94 miles), USGS said. Summary of todays M4.4 /HiI5eEgJXh- Hauraki Gulf Weather March 5, 2023 An earthquake of magnitude 6.9 struck Kermadec Islands region in New Zealand on Saturday, the United States Geological Survey (USGS) said. The cluster of main M4.0+ quakes have been around the Horomatangi Reef. This afternoon's M4.4 within the Taupō volcano caldera is the 3rd largest quake in the ongoing sequence which is now around 1,700 earthquakes since May 2022.
