Weston Geophysical Corp. conducted a series of chemical explosions using various explosives with different properties to investigate their effect on seismic signatures. Previous experimental data from the New England Damage Experiment (e.g., Martin et al., 2012) suggest that low‐frequency P‐wave amplitudes are affected by the explosive velocity of detonation and by the thermodynamic characteristics of gaseous explosive products (Stroujkova, 2015). The new experiment conducted in New Hampshire in 2016 was designed to isolate the effects of the amount of the explosive gases using aluminized and nonaluminized explosive pairs. The explosions were recorded using a network of seismometers and accelerometers fielded from near‐source to local distances. Seismic data from this experiment provide ground‐truth data that may be useful for future comparative studies of yield, based on seismic‐waveform analysis.
