In the following procedural outline, we detail the methodological steps for merging seismicity catalogs obtained from the Saudi Seismic Network and the Egyptian Seismic Network. This algorithm systematically guides the integration of seismic event data from these two distinct sources, emphasizing data accuracy, quality control measures, and conflict resolution to create a consolidated and standardized seismicity catalog:  
1. Saudi Seismic Network Catalog: * Import the seismic data from the Saudi Seismic Network catalog. * Identify unique events using distinctive event identifiers, such as event IDs and timestamps. * Exclude redundant events within to streamline the dataset. 2. Egyptian Seismic Network Catalog: * Import seismic data from the Egyptian Seismic Network catalog. * Identify events unique to Egyptian catalog using specific event identifiers for cross-referencing. * Eliminate redundant events within Egyptian catalog to enhance data clarity. 3. Common Event Identification: * Determine seismic events that exist in both catalogs, employing event identifiers. * Exclude duplicate events shared between the Saudi Seismic Network and the Egyptian Seismic Network catalogs. 4. Merge Process: * Combine the remaining unique events from both catalogs to create the merged seismicity catalog. Figure 3: Selected seismic data: a compilation of key earthquake parameters from the ENSN and SNSN datasets, highlighting spatial coordinates, and depth variations for the period 1997–2020. * Ensure the accuracy of metadata by updating information such as event location, magnitude, and depth. * Quality Control Measures:
* Implement rigorous quality control checks to address potential discrepancies and maintain data accuracy. * Resolve conflicts arising from discrepancies in seismic event information between the two catalogs. * Conflicting Data Strategy:
* Use 10 s origin time difference and 10 km epicentral distance difference between the two catalogs to manage conflicting data, prioritizing information from either the Saudi Seismic Network or the Egyptian Seismic Network. * Utilize additional data sources to resolve conflicts and ensure data consistency. * Data Format Standardization:
* Standardize the format of the merged seismicity catalog to ensure uniform representation. * Preserve the integrity of data presentation for subsequent analysis. * Document the merging process, including steps taken to resolve conflicts, quality control measures, and updates to metadata. * Provide a clear record of the synthesis of seismic data from the Saudi Seismic Network and the Egyptian Seismic Network catalogs. * Validation Checks:
* Perform validation checks on the merged catalog to confirm the success of the merging process. * Ensure that the resulting dataset aligns with expectations and maintains data integrity. * Final Review:
* Conduct a final review of the merged catalog to verify compliance with standards and the inclusion of all relevant seismic events. * Confirm that the merged dataset effectively represents the seismic activity captured by both the Saudi Seismic Network and the Egyptian Seismic Network. * Save and Export:
* Preserve the final merged seismicity catalog in the desired format for subsequent analytical endeavors. Figure 3 displays the geographic distribution of seismic activity in the Red Sea, emphasizing the spatial concentration of earthquakes.
