摘要

2016年2月6日当地时间11:00（协调世界时0900），夸祖鲁-纳塔尔省发生当地ML=3.8级地震。震中位于德班盆地近海。该省以及东开普省的东伦敦都有震感，多家国家媒体对此进行了报道。据报告有轻微结构损坏。地球科学委员会（CGS）与夸祖鲁-纳塔尔大学（UKZN）合作，使用问卷进行了一项宏观地震调查，得出了41个强度数据点。从美国地质调查局（USGS）获得了额外的强度数据点。你感觉到了吗？程序试图定义一个局部强度衰减模型。总的来说，低成本住宅区的地震感比富裕的郊区更强烈。

Macroseismic survey of the 6 February 2016 KwaZulu-Natal, South Africa earthquake

On the 6th of February 2016 at 11:00 hours local time (0900 UTC), KwaZulu-Natal was struck by an earthquake of local magnitude ML=3.8. The epicentre of the earthquake was located offshore in the Durban Basin. The earthquake shaking was widely felt within the province as well as in East London in the Eastern Cape province and was reported by various national media outlets. Minor structural damage was reported. A macroseismic survey using questionnaires was conducted by the Council for Geoscience (CGS) in collaboration with the University of KwaZulu-Natal (UKZN) which yielded 41 intensity data points. Additional intensity data points were obtained from the United States Geological Survey (USGS) Did You Feel It? programme. An attempt was made to define a local intensity attenuation model. Generally, the earthquake was more strongly felt in low-cost housing neighbourhoods than in more affluent suburbs.

期刊介绍： The South African Journal of Geology publishes scientific papers, notes, stratigraphic descriptions and discussions in the broadly defined fields of geoscience that are related directly or indirectly to the geology of Africa. Contributions relevant to former supercontinental entities such as Gondwana and Rodinia are also welcome as are topical studies on any geoscience-related discipline. Review papers are welcome as long as they represent original, new syntheses. Special issues are also encouraged but terms for these must be negotiated with the Editors.
