Description

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) Auxiliary Station AS41 in Jayapura plays a critical role in regional seismic monitoring as a broadband station. This study evaluates the data quality of AS41 using cross-correlation techniques to assess its performance relative to neighboring short period stations. The analysis highlights that AS41 records a significantly higher number of seismic events compared to nearby short period stations, attributed to its broadband design and superior sensitivity. The findings underscore the importance of AS41 in enhancing regional seismic event detection and provide insights for optimizing the integration of broadband stations into global seismic networks.
