The strong shallow earthquake with a moment magnitude (Mw) range between 6.6 and 7.0 according to different sources (AFAD, KOERI and USGS) took place at local time 14:51 on 30th October 2020, in Aegean Sea near Samos Island. According to the data given from Earthquake Department of the Disaster and Emergency Management Presidency (AFAD), the epicenter of the earthquake is 27.17km far away from the İzmir coast and the duration of the earthquake that occurred in 14.9km deep of the ground is 15.68s. The main shock of the earthquake brought about a small local tsunami that struck especially Seferihisar district in Izmir and Vathi in Samos. The main shock was followed by more than 5799 aftershocks with magnitudes varying between 0.7 and 5.1 in 62 days. Turkey, Greece and the islands in Aegean Sea felt the earthquake but it caused heavy damage and casualties at Bayraklı location in the city center of Izmir due to ground effects and structural problems. According to the data released after the field investigations made by the Turkish Ministry of Environment and Urbanization in the regions affected by the earthquake, 103 buildings collapsed and urgently demolished, 700 were severely damaged, 814 were moderately damaged, 7889 were slightly damaged and 159,000 were undamaged. The earthquake and tsunami resulted in 117 deaths and 1632 injured in Turkey, whereas two deaths and several injured in Samos, despite the distance between the epicenter and Turkey coast being more than Samos Island. One of these deaths occurred as a result of the tsunami and according to official sources; it was recorded as the first person to die from a tsunami in Turkey. This study aims to examine the damage and collapses that occurred on the structures due to the earthquake and the tsunami. The types and causes of damage that occurred on both reinforced concrete (RC) and masonry structures were evaluated in detail with taking into account the conditions of the existing Turkish Building Earthquake Design Code, [TBEC, [2018] Turkish Building Earthquake Design Code. Specifications for Structures to be Built in Disaster Areas (Earthquake Department of the Disaster and Emergency Management Presidency, Ankara, Turkey).] and previous Turkish Earthquake Codes (TECs).

2020 年 10 月 30 日爱琴海地震和海啸后的结构损坏评估

根据不同来源（AFAD、KOERI 和 USGS），2020 年 10 月 30 日当地时间 14:51，在萨摩斯岛附近的爱琴海发生了矩震级（Mw）范围在 6.6 和 7.0 之间的强浅层地震。根据灾害与应急管理总统府（AFAD）地震部提供的数据，地震震中为 27.17公里远离伊兹密尔海岸和 14.9 发生的地震持续时间地深15.68公里s。地震的主要冲击引发了一场小型的局部海啸，特别是袭击了伊兹密尔的 Seferihisar 区和萨摩斯岛的 Vathi。主震之后发生了超过 5799 次余震，震级在 62 天内在 0.7 和 5.1 之间变化。土耳其、希腊和爱琴海岛屿都感受到了地震，但由于地面效应和结构问题，在伊兹密尔市中心的Bayraklı地点造成了严重破坏和人员伤亡。根据土耳其环境与城市化部在地震灾区实地调查后公布的数据，103座建筑物倒塌并紧急拆除，700座严重受损，814座中度受损，7889座轻微受损，15.9万座受损完好无损。尽管震中与土耳其海岸之间的距离超过萨摩斯岛，但地震和海啸在土耳其造成 117 人死亡和 1632 人受伤，而在萨摩斯岛则造成两人死亡和数人受伤。根据官方消息，其中一人死亡是海啸造成的；它被记录为土耳其第一个死于海啸的人。本研究旨在检查地震和海啸对结构造成的破坏和倒塌。考虑到现有土耳其建筑地震设计规范 [TBEC, [2018] 土耳其建筑地震设计规范的条件，对钢筋混凝土 (RC) 和砖石结构发生损坏的类型和原因进行了详细评估。尽管震中和土耳其海岸之间的距离超过萨摩斯岛。根据官方消息，其中一人死亡是海啸造成的；它被记录为土耳其第一个死于海啸的人。本研究旨在检查地震和海啸对结构造成的破坏和倒塌。考虑到现有土耳其建筑地震设计规范 [TBEC, [2018] 土耳其建筑地震设计规范的条件，对钢筋混凝土 (RC) 和砖石结构发生损坏的类型和原因进行了详细评估。尽管震中和土耳其海岸之间的距离超过萨摩斯岛。根据官方消息，其中一人死亡是海啸造成的；它被记录为土耳其第一个死于海啸的人。本研究旨在检查地震和海啸对结构造成的破坏和倒塌。考虑到现有土耳其建筑地震设计规范 [TBEC, [2018] 土耳其建筑地震设计规范的条件，对钢筋混凝土 (RC) 和砖石结构发生损坏的类型和原因进行了详细评估。它被记录为土耳其第一个死于海啸的人。本研究旨在检查地震和海啸对结构造成的破坏和倒塌。考虑到现有土耳其建筑地震设计规范 [TBEC, [2018] 土耳其建筑地震设计规范的条件，对钢筋混凝土 (RC) 和砖石结构发生损坏的类型和原因进行了详细评估。它被记录为土耳其第一个死于海啸的人。本研究旨在检查地震和海啸对结构造成的破坏和倒塌。考虑到现有土耳其建筑地震设计规范 [TBEC, [2018] 土耳其建筑地震设计规范的条件，对钢筋混凝土 (RC) 和砖石结构发生损坏的类型和原因进行了详细评估。灾区建筑物规范（土耳其安卡拉灾害和应急管理总统府地震部）。] 和以前的土耳其地震代码 (TECs)。
