This study focuses on the validation and applicability of a recently modified semi-empirical technique (MSET) to integrate site effects. The improvement of MSET by considering site effects has been verified by the data of the 1988 Indo-Burma earthquake (M_w 7.2), which happened in the North Eastern Region (NER) in India. This technique is also used to model a future scenario earthquake (M_w 8.2) in the NER. The required site effects are estimated using Nakamura’s horizontal-to-vertical (H/V) ratio technique for 89 waveform records. The obtained site effects are further used to modify an existing semi-empirical technique. To validate this modification, the strong-motion records of the 1988 Indo-Burma earthquake are simulated for bedrock and surface conditions. Afterwards, the root mean square error (RMSE) of these records is compared with surface records obtained by 14 seismic stations. The records simulated at the surface are well validated well with observed ones as compared to the records simulated at bedrock and hence confirm the reliability of the MSET. The improved performance of the MSET after incorporation of site effects validates the approach of the present work and will prove to be significant for simulation of earthquake surface conditions in any region. Further, this improved MSET is used to simulate strong-motion records of a future scenario earthquake (M_w 8.2) with the same epicentral location. The iso-acceleration maps are prepared from simulated records for both cases (M_w 7.2 and 8.2), which provide peak ground acceleration (PGA) values of more than 500 and 1000, respectively, for near-field regions. The obtained results are of significant interest for seismic hazard assessment of NE India.

本研究侧重于最近改进的半经验技术 (MSET) 的验证和适用性，以整合场地效应。1988 年发生在印度东北地区 (NER)的印缅地震 ( M _w 7.2)的数据证实了考虑场地效应的 MSET 改进。该技术还用于模拟NER 中的未来情景地震 ( M _w 8.2)。使用 Nakamura 的水平到垂直 ( H / V) 89 个波形记录的比率技术。获得的现场效应进一步用于修改现有的半经验技术。为了验证这种修改，我们模拟了 1988 年印缅地震的强震记录的基岩和地表条件。然后，将这些记录的均方根误差 (RMSE) 与 14 个地震台站获得的地面记录进行比较。与在基岩模拟的记录相比，在地表模拟的记录与观测记录得到了很好的验证，因此证实了 MSET 的可靠性。结合场地效应后 MSET 的改进性能验证了当前工作的方法，并将证明对于模拟任何地区的地震地表条件都具有重要意义。更多，M _w 8.2) 具有相同的震中位置。等加速度图是根据两种情况（M _w 7.2 和 8.2）的模拟记录准备的，它们分别为近场区域提供了超过 500 和 1000 的峰值地面加速度 (PGA) 值。获得的结果对印度东北部的地震危险性评估具有重要意义。
