Natural and manmade sources at or near the solid earth atmosphere boundary can generate waves in both the solid earth and atmosphere. The location and characterization of these sources can benefit from the analysis of both sets of waves. This report documents work first to investigate and develop new detection and location methods for infrasound signals low frequency acoustic signals that can be combined with seismic observations and thus applied to data recorded by regional seismo-acoustic arrays. Several empirical studies are reported that exercised these tools with complementary ground truth information in order to assess the adequacy of the new tools. Finally the automated procedures were tested and tuned for two regional seismo-acoustic networks in Korea and the western US. Automated bulletins were produced for these two networks and compared, providing constraints for additional work.
