Seismicity variation along with crustal heterogeneity using natural source is of prime interest in advance research nowadays. In the global scenario, North-East India is one of the prominent seismicity active zone characterized by its tectonically complex set-up. The seismicity study area encompasses between 18°–32°N latitude and 88°–102°E longitude, which basically locates the Shillong plateau and its surrounding in north-east part of India. Here, we have attempted to forecast the seismicity pattern as well as the crustal heterogeneity for Shillong plateau in north-east part of India. In this regard, we have used the most basic seismicity parameter like b value and fractal correlation dimension (D_c) along with focal mechanism characteristic over the entire region of study. The correlation experiment between the lower D_c value and b value indicates the possibility of an earthquake of large magnitude in the south central Burma basin and Shillong plateau region. Various dynamic faults and associated seismicity spread over all around the North-East India supports the possible rejuvenation of pop-up structure for Shillong plateau. We have tested our proposed method on real dataset, presented and analysed our experimental results and compared it with other methods and the overall results are found to be satisfactory.

如今，利用自然资源进行的地震变化和地壳异质性是当今研究的主要关注点。在全球范围内，印度东北部是其构造构造复杂的特点，是最著名的地震活动区之一。地震活动性研究区的纬度在北纬18°–32°至东经88°–102°之间，基本上位于印度东北部的西隆高原及其周围地区。在这里，我们试图预测印度东北部西隆高原的地震活动模式以及地壳异质性。在这方面，我们使用了最基本的地震活动性参数，例如b值和分形相关维数（D _c）以及整个研究范围内的焦点机制特征。较低的D _c值与b值之间的相关性实验表明，在缅甸中南部盆地和西隆高原地区可能发生大地震。分布在印度东北部各地的各种动态断层和相关的地震活动支持西隆高原的弹跳结构可能恢复生气。我们已经在真实数据集上测试了我们提出的方法，展示并分析了我们的实验结果，并将其与其他方法进行了比较，发现总体结果令人满意。
