The Makran Accretionary Wedge (900 km across) is a consequence of northward subduction of the oceanic part of the Arabian Plate beneath the Lut and Afghan blocks in the northwestern Indian Ocean. It has a complicated tectonic setting as it is located at a triple junction with the Indian Plate. Thick sedimentary layers, a shallow angle of the subducting slab and a large width of the subduction zone, ca. 500–600 km from volcanic arc to active wedge front, are some of the foremost and distinctive characteristics of the Makran Subduction Zone (MSZ). The MSZ is likely divided into at least two segments: the west and the east possibly separated by a sinistral fault known as the Sonne Fault. A division is also inferred from seismicity as it is higher in the east when compared to the west. With the exception of a notable trench, all other characteristics of an accretionary prism observed in well-studied subduction zone can be identified or inferred in the Makran. Three long seismic profiles of the western Makran (200 km long each, with shot points interval of 20 km and receivers interval of 700 m) have recently been acquired. Using these datasets, improved structural/velocity models for the western Makran were developed. This review aims to contribute to achieving a better understanding of the seismotectonic setting and dynamics of the Makran Subduction Zone as it feeds to a refined understanding of the tsunami hazard in the region.

作为海啸危害评估基线的Makran俯冲带地震构造学评论

Makran增生楔（宽900公里）是印度洋西北部Lut和Afghan区块下方阿拉伯板块海洋部分向北俯冲的结果。它位于与印度板块的三重交界处，具有复杂的构造环境。厚的沉积层，俯冲板片的夹角较小，俯冲带的宽度较大，约 从火山弧到活动楔前缘500-600 km是Makran俯冲带（MSZ）的一些最重要的独特特征。MSZ可能至少分为两个部分：西部和东部可能被称为Sonne断层的左旋断层隔开。从地震活动也可以推断出一个划分，因为与西方相比，东方的划分更高。除了明显的战trench 在经过充分研究的俯冲带中观察到的增生棱镜的所有其他特征，可以在Makran中识别或推断。最近已经获得了西部Makran的三个长地震剖面图（每个长200 km，射点间隔为20 km，接收器间隔为700 m）。使用这些数据集，开发了西部Makran的改进的结构/速度模型。这项审查旨在有助于更好地了解Makran俯冲带的地震构造背景和动力学，因为它有助于对该地区海啸灾害的精细了解。炮点间隔为20 km，接收器间隔为700 m）最近已获得。使用这些数据集，开发了西部Makran的改进的结构/速度模型。这项审查旨在有助于更好地了解Makran俯冲带的地震构造背景和动力学，因为它有助于对该地区海啸灾害的精细了解。炮点间隔为20 km，接收器间隔为700 m）最近已获得。使用这些数据集，开发了西部Makran的改进的结构/速度模型。这项审查旨在有助于更好地了解Makran俯冲带的地震构造背景和动力学，因为它有助于对该地区海啸灾害的精细了解。
