### Discrepancies in Collected Seismicity Data
SANDSN exhibits a modest range of variation, while SNSN maintains a relatively stable pattern, with fewer deviations that could be outliers. Ranking the networks by the apparent number of outliers or deviations, KSUSN has the most notable fluctuations across all temporal scales, possibly indicative of outlier contamination. SANDSN follows with a moderate degree of variability, and SNSN is last, displaying the least variability and suggesting a more uniform data collection process. The analysis of the spatial distribution of seismic data, as depicted in Figure 6, offers valuable insights into the dynamics of the rifting zones. The precise locations of earthquake clusters, in relation to established geological features, can shed light on the current state of rifting and the kinematics of the tectonic plates involved. Figure 5(a,c) illustrates the spatial distribution of seismic events in relation to geographic latitude and longitude, as recorded by the KSUSN, SANDSN, and SNSN seismic networks. These figures include marginal histograms that summarize the univariate distributions of earthquake magnitudes and geographic coordinates. Contour overlays superimposed on the scatter plots highlight areas of increased seismic activity, revealing pronounced

These clusters, marked by peaks within the contour lines, signify a heightened frequency of seismic activity, which is critical for seismic hazard assessment and mitigation strategies. Additionally, the marginal histograms reveal a predominance of low-magnitude seismic events, with frequencies decreasing as magnitudes increase, which is consistent with recognized seismicity patterns. The distributions of seismicity across geographic axes, as captured by the different networks, may reflect the operational ranges and detection sensitivities of these systems. Furthermore, the spatial distribution of seismic events reveals a concentration of earthquakes along specific latitudinal and longitudinal bands, likely related to the rifting dynamics of the Red Sea and the adjacent Gulf of Suez and Gulf of Aqaba. The histograms indicate that the majority of seismic events are low in magnitude, a common characteristic of rifting zones where the crust undergoes extension, resulting in numerous but typically minor earthquakes as the lithosphere accommodates the tensional forces. Figure 6b,d illustrates the distributions of earthquake depths in relation to latitude and longitude, respectively. The histograms located at the top of the plots reveal a notable aggregation of earthquake occurrences at specific latitudinal and longitudinal coordinates. Correspondingly, the depth histograms positioned on the right side of the figures highlight a predominance of shallow earthquakes over deeper ones. Both figures exhibit a discernible trend of decreasing earthquake frequency with increasing depth, as observed from the concentration of points near the bottom axis--a distribution pattern that aligns with global observations, where shallow earthquakes are more frequent than their deeper counterparts. The contour lines in the scatter plots represent kernel density estimations, furnishing a smoothed portrayal of point density that underscores areas with elevated earthquake frequencies. The clustering of seismic events at particular depths and geographic coordinates suggests the existence of fault lines or rifting zones. Furthermore, the aggregation of earthquakes at distinct latitudes and longitudes points to potential areas of intense tectonic activity, such as spreading centers or transform faults, indicative of divergent plate boundaries similar to those found in the Red Sea region. The prevalence of shallow seismicity indicates that tectonic deformation is predominantly taking place near the Earth's surface, which is characteristic of nascent spreading centers like that of the Red Sea.
