Rapid investigation of co and post-seismic deformation resulting from the 24th August 2016 Amatrice Earthquake (M 6.2)

8月24日凌晨3点36分，阿马特里切地区发生6.2级地震。这次地震造成近300人死亡，并对分布在该地区的村庄造成重大破坏。地震跨越了两条断层，拉加-阿马特里切断层和维托雷断层，这两条断层以前被认为是独立的结构，不可能在一次事件中破裂。我们的小组在地震发生几天后访问了该地区，开始对这次地震进行科学研究，调查地震的表面表现，并安装全球导航卫星系统设备，该设备将在地震发生后数周和数月连续测量地面的高分辨率运动。我们的团队由来自利兹大学、达勒姆大学、伦敦大学、伦敦伯克贝克大学、印度大学、意大利地质调查局(ISPRA)和地理空间研究有限公司(Durham)的英国和意大利科学家组成。我们团队的成员是使用卫星数据调查地面变形(Durham)的专家，他们实时处理数据以指导最初的现场活动。该项目的目标是根据地震期间发生的事情和地震发生后继续发生的事情，全面描述阿马特里切地震的性质。我们将使用各种技术，包括卫星雷达测量和地震后形变模拟、GNSS(全球导航卫星系统)地面形变测量、摄影测量和激光扫描以对地表破裂进行高分辨率测量、地震区域的详细实地工作以及确定这次地震如何影响周围断层上的应力的模拟技术。这项工作迫在眉睫，因为需要记录地震后几周和几个月内的震后变形，以及地表破裂的退化性质。这项研究将使我们能够调查断层的连通性以及联系是如何发展的。我们将检验有关地震后震后变形作用的假设，这些地震是连接以前独立的结构的。断层联系通常发生在漫长的地质时间尺度上，以前从未用如此高质量的数据集捕捉到过。我们的结果将对将多断层破裂地震纳入意大利中部和全球未来的危险评估具有重要意义。

At 3:36 AM on the 24th of August a magnitude 6.2 earthquake struck the Amatrice region. The shaking in this event caused nearly 300 deaths and significant damage to the villages distributed across the region. The earthquake ruptured across two faults, the Laga-Amatrice and Vettore faults, which were previously thought to be separate structures that could not rupture in a single event. Our team visited the region days after the event to begin scientific study of this earthquake, investigating the surface expression of the earthquake and installing GNSS equipment that will measure high-resolution motion of the ground continuously for weeks and months following the earthquake. Our team comprises UK and Italian scientists from the University of Leeds, University of Durham, Univeristy of London, Birkbeck University of London, University of Insurbia, the Italian Geological Survey (ISPRA), and Geospatial Research Ltd (Durham). Members of our team who are experts in using satellite data to investigate ground deformation (Durham) processed data in real-time to direct the initial field campaign.This project will aim to fully characterise the nature of the Amatrice earthquake in terms of what happened during and what is continuing to occur after the seismic event. We will use a variety of techniques including satellite radar measurements and modelling of co and post -seismic deformation, GNSS (Global Navigation Satellite System) measurements of ground deformation, photogrammetry and laser scanning to make high resolution measurements of the surface rupture, detailed field work in the region of the earthquake, and modelling techniques to determine how this earthquake affected stress on the surrounding faults. The work is urgent due to the need to document post-seismic deformation in the weeks and months following the earthquake, and the degrading nature of the surface rupture. This research will allow us to investigate fault connectivity and how linkage develops. We will test hypotheses regarding the role of postseismic deformation after an earthquake that links previously independent structures. Fault linkage typically happens over long geological timescales and has never before been captured before with such a high quality dataset. Our results will be important for incorporating multi-fault rupturing earthquakes into future hazard assessments made in central Italy and globally.
