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

2016年8月24日凌晨3时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，靠近阿库库利村，断层破裂25公里。罗马(西南120公里)、佛罗伦萨(西北220公里)和乌尔比诺(北部200公里)都有震感。受影响最严重的地区震中周围半径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瓦砾砖石结构组成，还有少量钢筋混凝土建筑。前者的表现非常差，崩溃现象普遍存在。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，但主震发生的时间以及许多旅游民宿几乎满员的事实导致死亡人数为295人，受伤388人，2000多人无家可归。这是自1980年以来意大利发生的第二次最致命的地震。自1982年以来，地震工程调查小组(EEFIT)在全球范围内组织了数十次侦察任务。涉及英国学者和工业合作伙伴的这些任务过去一直由EPSRC通过紧急资金申请机制提供资金。EEFIT是一群地震工程师、建筑师和学者，他们与地震多发国家的同事合作，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现场调查，并向工程界报告他们的发现。EEFIT特派团的主要目标是：-对受影响区域内的结构、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--评估地震防御方法的有效性，包括修复和翻新，并将结构的实际性能与设计者的预期进行比较--研究灾害管理程序和地震的社会经济影响，这些目标与阿马特里切地震地区的任务目标相一致，并在这些目标中得到进一步阐述。10名学者和5个工业伙伴将参加这项任务，该任务将部署长达两周，对受地震影响的建筑物进行快速和详细的破坏调查。该小组将与地方当局和意大利地球物理机构联系，收集有关地震方面的数据。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.
