The purpose of this project is to deploy ten temporary seismic stations in the Wellington region on New Zealand's North Island. The recorded seismicity will help constraint the rupture area of the Kaikoura Mw= 7.8 earthquake that occurred in the northern part of New Zealand?s South Island on November 13, 2016. The main motivation for deploying instruments in this region is the potential for earthquakes migrating northwards onto or being triggered on the subduction megathrust located beneath the Wellington area and/or on crustal faults that cut through the region surrounding the capital of New Zealand.Stress change calculations show that the area near Wellington has been subjected to an increase in earthquake-causing stress. The plan is to deploy the temporary seismic instruments at sites previously used in the 2009-2011 SAHKE project, concentrating on redeploying in the southwestern part of the former array. This will yield an average station spacing of about 12 km. We will work directly with our collaborators in Victoria University of Wellington on the siting plan, and we will take advantage of their landowner connections for facilitating permitting. We expect to run the stations for about 6 months. Once the instruments are removed and shipped back to the U.S., the data will be converted to a standard archive format and provided to the IRIS Data Management Center, along with the metadata, within one month.

该项目的目的是在新西兰北岛的惠灵顿地区部署十个临时地震站。记录的地震行为将有助于限制2016年11月13日在新西兰南岛北部发生的Kaikoura MW = 7.8地震。围绕新西兰的首都。压力变化计算表明，惠灵顿附近的区域受到了地震造成的压力的增加。该计划是将临时地震仪器部署在先前在2009 - 2011年Sahke项目中使用的地点，并集中于以前阵列西南部的重新部署。这将产生约12公里的平均车站间距。我们将直接与惠灵顿维多利亚大学的合作者合作制定选址计划，我们将利用他们的土地所有者联系来促进许可。我们预计将运行大约6个月。删除仪器并将其运回美国后，数据将在一个月内将数据转换为标准的档案格式，并与元数据一起提供给IRIS数据管理中心。
