Benouar博士介绍了对阿尔及利亚和邻近地区在二十世纪最近地震活动的全面和综合研究。他积累了大量与个别地震有关的宏观地震信息，并将其与仪器信息相结合，重新评估每个事件的起源参数。在任何地震的汇编中，除了简单的数字和事实的积累之外，还有更多的信息，这些信息增加了对地震本身的科学评价的兴趣和社会理解。要做到这一点，就必须了解当地的情况，贝努阿尔博士非常生动地向我们展示了本世纪不同时期的报告程序之间的差异，以及随之而来的困难。对于一个局外人来说，收集他所提供的信息是最困难的，他很好地利用了他对家乡的了解，以及他作为工程师的专业训练。因此，我们了解到，殖民国家不愿意报告侨民社区遭受的损失或伤亡以外的损失或伤亡，而且在独立战争期间，即使是大地震的影响有时也比战争本身的影响小，因此，一般很难找到有关地震的资料。他也没有给我们提供最近地震后重建期间出现的政治困难的细节。然而，这项工作并不限于描述。他研究了该地区的基本构造，并推断出该国各地的危害和风险估计。然后，他继续研究工程后果，并讨论未来的需要，建筑规范和民事保护。Benouar博士的工作很可能为那些希望对其他地区的地震活动性进行综合研究的人提供一个模型，以及减少灾难性地震影响所需的措施。
Dr. Benouar presents a full and integrated study of the recent seismicity of Algeria and adjacent regions during the twentieth century. He has amassed an impressive amount of macroseismic information pertaining to individual earthquakes, which he combines with instrumental information to reassess the origin parameters of each event. In any compilation of earthquakes it is the additional information beyond the bare accumulation of figures and facts that adds interest and social understanding to the scientific appreciation of the earthquakes themselves. For this it is necessary to know the local conditions, and Dr. Benouar brings out for us very vivid1y the differences between reporting procedures at different times this century, and the ensuing difficulties. It would be most difficult for an outsider to gather the information he presents, and he makes good use of his knowledge of his native land, as well as his professional training as an engineer. We thus learn of the reluctance of the colonial powers to report on damage or casualties outside those inflicted on the expatriate community, and the general difficulties of finding information about earthquakes that occurred during the wars of independence, at a time when effects of even major earthquakes were sometimes minor compared to those of the war itself. He also does not spare us details of political difficulties that arose during periods of reconstruction following recent earthquakes. This work is not restricted, however, to description. He examines the underlying tectonics of the area and deduces estimates of hazard and risk in various parts of the country. He then proceeds to examine the engineering consequences and discuss future needs for building codes and civil protection. Dr. Benouar has produced a work which could well form a model for those wishing to undertake comprelzensive studies of seismicity of other areas, and the measures needed to reduce the effects of catastrophic earthquakes.
