Explosion Seismology Applications and Advances

Explosion sources are an important component of seismology. They can be tools to characterize the sub-surface for a variety of applications using established networks as well as inexpensive and easy to deploy arrays/networks of sensors. As a result, the wavefield produced by explosions is being studied with unprecedented detail. In regions of low natural background seismicity, mine blasting can dominate monitoring catalogs and identifying and separating these sources from tectonic earthquakes is important for hazard assessment. The seismo-acoustic signals from accidental explosions can be used in their forensic analysis and to study propagation issues. Recordings of surface explosions can illuminate geologic structures in regions where there is a lack of seismicity to better characterize the velocity structure. Recent work using template matching, waveform modeling for moment tensors and combining seismo-acoustic data has shown great success in characterizing explosions and discriminating them from earthquakes and other sources. We welcome abstracts in explosion source physics, wave propagation, Large-N network design, distributed acoustic sensing (DAS), new sensor technologies, multi-physics data fusion and advanced processing techniques applied to explosion sources.
