MBASS-vs-EMR-Method

The aim of the 'MBASS vs EMR for Completeness Magnitude in Indian catalogue' project was to compare the effectiveness of two widely used methods for determining the completeness magnitude (Mc) of earthquake catalogues in the Indian region. The two methods that were compared were the Median Based Analysis of the Segment Slope (MBASS) method and the Entire Magnitude Range (EMR) method. The Indian earthquake catalogue was used as the dataset for the project, which contains a large amount of data that can be used to assess the seismicity of the region. The MBASS method involves analyzing the slope of the frequency-magnitude distribution (FMD) of earthquakes in a catalogue to determine Mc. On the other hand, the EMR method involves comparing the observed FMD of earthquakes to the theoretical FMD expected for a complete earthquake catalogue. The results of the project showed that both the MBASS and EMR methods provided consistent and reliable Mc estimates for the Indian earthquake catalogue. The MBASS method identified Mc to be around 3.8 , while the EMR method estimated it to be between 3.4 and 3.7. The consistency between the two methods highlights the reliability of the Indian earthquake catalogue. The study provides valuable insights into the applicability of the MBASS and EMR methods for assessing Mc in other earthquake catalogues. The findings suggest that both methods can be used as complementary tools for assessing the completeness magnitude of earthquake catalogues. The results of the project have important implications for seismic hazard analysis and earthquake prediction in the Indian region. Accurate and reliable assessments of Mc are crucial for understanding the seismicity of a region and for estimating the potential maximum earthquake magnitude that could occur in the future.
