Explosion Seismology Applications [Poster]
Date: 4/24/2019
Room: Grand Ballroom
Explosion sources are an important component of seismology and are used in everything from characterization of geologic environments to nuclear test identification. In regions of low natural background seismicity, mine blasting can dominate monitoring catalogs and finding and separating these sources from tectonic earthquakes is important for hazard estimation. Recent work using template matching, waveform modeling for moment tensors and combining seismic and acoustic data has shown great success in discriminating explosions from earthquakes and other sources. With the advent of inexpensive and easy to deploy arrays and networks of sensors, the wavefield produced by explosions is being studied with unprecedented detail. We welcome abstracts on explosion source physics, wave propagation, large-N network design, multi-physics data fusion and advanced processing techniques applied to explosion sources.
