EEFIT RECONNAISSANCE MISSION TO THE AMATRICE, ITALY 24/09/2016 EARTHQUAKE

2016年8月24日凌晨3点36分，意大利中部地区发生6.2级地震，震中位于亚平宁山脉，靠近阿加普里村，断层破裂25公里。远至罗马（西南120公里）、佛罗伦萨（西北220公里）和乌尔比诺（北200公里）都有震感。受影响最严重的地区以震中为中心方圆20公里，包括翁布里亚、拉齐奥和阿布鲁佐地区的一些城镇和小村庄。这些城市中心的建筑主要由历史悠久的碎石砌体结构组成，并有少量的钢筋混凝土结构。前者的表现很差，崩溃很普遍。阿马特里切的历史建筑遭到了广泛的破坏。虽然该地区人口稀少，但主要地震发生的时间和大部分旅游住宿几乎满负荷的事实导致死亡人数为295人，受伤人数为388人，2000多人无家可归。这是自1980年以来意大利发生的第二大地震。自1982年以来，地震工程调查队（EEFIT）在世界范围内组织了数十次侦察任务。涉及英国学术界和工业合作伙伴，在过去，这些任务是由EPSRC通过紧急资金申请机制资助的。EEFIT是一个由地震工程师、建筑师和学者组成的团体，他们与地震易发国家的同事合作，提高传统和工程结构的抗震能力。EEFIT的主要活动是在大地震后进行实地调查，并将调查结果报告给工程界。EEFIT任务的主要目标是：-对受影响地区内的结构、基础、土木工程和工业厂房的性能进行详细的技术评估-收集地质和地震数据，包括强震记录-评估地震防护方法的有效性，包括修复和改造；并将结构的实际性能与设计师的期望进行比较-研究灾害管理程序和地震的社会经济影响，包括人员伤亡。这些目标与阿马特里切地震地区特派团的目标相一致，并得到进一步阐明。10名学者和5个工业合作伙伴将参与此次任务，该任务将部署长达两周的时间，对受地震影响的建筑物进行快速和详细的损坏调查。该小组将与地方当局和意大利地球物理机构联系，收集地震的地震学数据。最后，它将向英国和意大利社区报告实地考察的结果。

At 3.36 am on 24th August 2016 a Mw 6.2 earthquake struck the central region of Italy, with epicentre in the Apennines range, near the village of Accumuli and with a fault rupture of 25 km. Earthquake shaking was felt as far as Rome (120 km SW), Florence (220 km NW) and Urbino (200 km N). The worst affected region has a radius of 20 km around the epicentre, including a number of towns and small villages across the regions of Umbria, Lazio and Abruzzo. The building stock of these urban centres mainly consists of historic rubble masonry structures, with a small measure of reinforced concrete construction. The performance of the former was very poor and collapse was widespread. The historic building stock of Amatrice suffered widespread destruction. Although the area is sparsely populated, the time of occurrence of the main shock and the fact that much of the tourist accommodation was nearly at full capacity led the death toll to be 295, injured 388 and left more than 2000 people homeless. This was the second most deadly earthquake in Italy since 1980.Since 1982, the Earthquake Engineering Investigation Team (EEFIT) has organised dozens of reconnaissance missions worldwide. Involving UK academics and industrial partners, in the past these missions have been funded by EPSRC through the urgent funding request mechanism. EEFIT is a group of earthquake engineers, architects and academics who collaborate with colleagues in earthquake prone countries to improve the seismic resistance of both traditional and engineered structures.EEFIT's principle activity is conducting field investigations following major earthquakes and reporting their findings to the engineering community. The main objectives of EEFIT missions are:- To carry out a detailed technical evaluation of the performance of structures, foundations, civil engineering works and industrial plant within the affected region- To collect geological and seismographic data, including strong motion records- To assess the effectiveness of earthquake protection methods, including repair and retrofit, and to make comparisons of the actual performance of structures with the expectations of designers- To study disaster management procedures and socio-economic effects of the earthquake, including human casualties.These objectives correspond and are further articulated in the objectives of this mission to the Amatrice earthquake region.Ten academics and 5 industrial partners will take part in the mission which will deploy for up to two weeks, conducting rapid and detailed damage surveys of buildings affected by the earthquake. The team will liaise with the local authority and the Italian geophisical institution to collect data on the seismological aspects of the shaking. Finally it will report to the UK and Italian communities its findings from the field trip.
