1974-1975 年，用 Zemlya 仪器沿着古巴东部的一系列区域剖面记录了转换折射地震波 (CREW)（图 1）。这些记录使我们能够追踪稳定的 F1、F2 和 M 转换边界，这些边界与地下室的表面相同。还可分别追踪“玄武岩”层和 MohoroviEi6 不连续性，以及几个具有范数分布或速度反演的相当广泛的边界。地壳地层的绝对速度是根据实验和工业爆炸的折射波数据确定的，从而可以在20-120公里的距离处获得纵波和横波全息图。这项工作是在该岛西部进行的类似调查的延续，其结果已经发表 (5, 6)。
In 1974-1975, converted refracted earthquake waves (CREW) were recorded with'the Zemlya apparatus along a series of regional profiles in Eastern Cuba (fig. 1). The recordings enabled us to trace the stable F1, F2 and M conversion boundaries, which are identical to the surfaces of the basement. Also trace-able are the" basaltic" layer and the MohoroviEi6 discontinuity respectively, as well as several rather extensive boundaries with either norm4 distribution or a velocity inversion. The absolute velocities in the crustal strata were determined from data on refracted waves from experimental and industrial explo-sions, making it possible to obtain P and S wave holograms at distances up to 20-120 kilometers. This work was a continuation of similar investigations performed in the western part of the island, results of which have already been published (5, 6).
