The present paper discusses the seismicity of Africa and the need for the implementation of vibration control strategies in Africa, erroneously considered as aseismic. The review catalogues information on the seismicity of Africa, attesting that virtually every region in the African continent has come under the threat of some form of seismic event. The magnitudes and intensities of these seismic activities has resulted in devastations, including: loss of lives, building and civil structures collapse, displacements of people, economic losses, psychological traumatization, and grave fear. Evidences available show that most of the devastations are accentuated by tremor induced collapse of buildings and civil structures. It is thus imperative for substantive, simply implementable, and sustainable proactive measures for controlling the threats of seismic events be discussed within the African context. Current mitigation strategies in Africa include the establishment of seismic codes which govern the design of civil structures. The challenge to the implementation and the effectiveness of the existing African seismic codes was briefly discussed, and new measures which can reduce seismic risks were also highlighted The submissions of the paper is envisaged will create awareness on the budding seismic activities in Africa and awaken relevant authorities on the need for timely and practicable mitigation strategies to be in place to avert the attendant catastrophes associated with seismic occurrences.

对非洲地震活动的严格评估和缩减政策–回顾

本文讨论了非洲的地震活动性以及在非洲实施振动控制策略的必要性,这些策略被误认为是抗震的。该评论对有关非洲地震活动的信息进行分类,证明非洲大陆几乎每个地区都受到某种形式的地震事件的威胁。这些地震活动的强度和强度造成了破坏,包括:生命损失,建筑物和土木结构坍塌,人员流离失所,经济损失,心理创伤和严重恐惧。现有证据表明,大多数破坏是由于地震引起的建筑物和土木结构倒塌而加剧的。因此,实质性的,简单的实施,在非洲范围内讨论了控制地震事件威胁的可持续主动措施。非洲目前的缓解策略包括制定规范民用建筑设计的地震法规。简要讨论了现有非洲地震法规的实施挑战和有效性,并重点介绍了可以降低地震风险的新措施。设想该论文的提交将使人们对非洲正在萌芽的地震活动有所认识,并唤醒有关当局需要采取及时可行的缓解策略来避免与地震相关的随之而来的灾难。非洲目前的缓解策略包括制定规范民用建筑设计的地震法规。简要讨论了现有非洲地震法规的实施挑战和有效性,并重点介绍了可以降低地震风险的新措施。设想该论文的提交将使人们对非洲正在萌芽的地震活动有所认识,并唤醒有关当局需要采取及时可行的缓解策略来避免与地震相关的随之而来的灾难。非洲目前的缓解策略包括制定规范民用建筑设计的地震法规。简要讨论了现有非洲地震法规的实施挑战和有效性,并重点介绍了可以降低地震风险的新措施。设想该论文的提交将使人们对非洲正在萌芽的地震活动有所认识,并唤醒有关当局需要采取及时可行的缓解策略来避免与地震发生相关的随之而来的灾难。
