Abstract

On February 6, a successive rupture of major faults in the Eastern Anatolian Fault Zone and Cardak-Surgu fault triggered a strong mainshock (Mw 7.7) and a major aftershock (Mw 7.6) in Kahramanmaras. The successive earthquake sequence hit southern provinces in Türkiye and northern regions in Syria, causing severe fatality and economic loss. After the earthquakes, the International Consortium on Geo-disaster Reduction (ICGdR) organized an investigation team, involving specialists from China, Japan and Türkiye, to conduct a primary field reconnaissance on seismic damage of infrastructure and ground failures. The 10-day reconnaissance, including a mini-symposium at the Istanbul Technical University (ITU), was conducted from 25 March to 3 April and specifically focused on fault ruptures, liquefaction, landslide, rockfall and lateral spreading along the major ruptured faults from Antakya in Hatay to Goksun in Kahramanmaras, passing through provinces of Gaziantep, Adıyaman and Malatya. By this reconnaissance, a large amount of original seismic data was collected and a primary understanding was established for further steps on mitigation and reduction of seismic damages and its secondary geohazards.

2023 年 2 月 6 日土耳其卡赫拉曼马拉什地震实地考察初步报告

2 月 6 日，东安纳托利亚断裂带和卡达克-苏尔古断裂的主要断层相继破裂，在卡赫拉曼马拉什引发了一次强烈的主震（7.7 级）和一次强烈的余震（7.6 级）。连续的地震袭击了土耳其南部省份和叙利亚北部地区，造成了严重的人员伤亡和经济损失。地震发生后，国际地质灾害减灾联合会（ICGdR）组织了一个由来自中国、日本和图尔基耶的专家组成的调查小组，对地震造成的基础设施破坏和地面塌陷进行了初步实地考察。这次为期 10 天的考察，包括在伊斯坦布尔技术大学（ITU）举行的小型研讨会，于 3 月 25 日至 4 月 3 日进行，重点考察了从哈塔伊省 Antakya 到卡赫拉曼马拉什省 Goksun（途经加济安泰普省、阿德亚曼省和马拉蒂亚省）主要断裂断层沿线的断裂、液化、滑坡、落石和横向扩展情况。通过这次勘察，收集了大量原始地震数据，并为进一步采取措施减轻和减少地震破坏及其次生地质灾害建立了初步认识。

期刊介绍： Geoenvironmental Disasters is an international journal with a focus on multi-disciplinary applied and fundamental research and the effects and impacts on infrastructure, society and the environment of geoenvironmental disasters triggered by various types of geo-hazards (e.g. earthquakes, volcanic activity, landslides, tsunamis, intensive erosion and hydro-meteorological events). The integrated study of Geoenvironmental Disasters is an emerging and composite field of research interfacing with areas traditionally within civil engineering, earth sciences, atmospheric sciences and the life sciences. It centers on the interactions within and between the Earth''s ground, air and water environments, all of which are affected by climate, geological, morphological and anthropological processes; and biological and ecological cycles. Disasters are dynamic forces which can change the Earth pervasively, rapidly, or abruptly, and which can generate lasting effects on the natural and built environments. The journal publishes research papers, case studies and quick reports of recent geoenvironmental disasters, review papers and technical reports of various geoenvironmental disaster-related case studies. The focus on case studies and quick reports of recent geoenvironmental disasters helps to advance the practical understanding of geoenvironmental disasters and to inform future research priorities; they are a major component of the journal. The journal aims for the rapid publication of research papers at a high scientific level. The journal welcomes proposals for special issues reflecting the trends in geoenvironmental disaster reduction and monothematic issues. Researchers and practitioners are encouraged to submit original, unpublished contributions.
