T2.3 - Seismoacoustic Sources in Theory and Practice

Oral

The International Data Center (IDC) analyze routinely seismoacoustic data for producing a list of seismoacoustic events as part of the Comprehensive Nuclear-Test Ban Treaty (CTBT) verification regime.
However, the fusion between seismic and infrasound date is not yet satisfactory.
A set of seismoacustic events with known location, origin time and if possible their energy, is necessary in...

T2.3 - Seismoacoustic Sources in Theory and Practice

Oral

For low-yield monitoring applications, the combined analysis of seismic and infrasound data could lead to significant improvements in our understanding of the processes that simultaneously generate both types of signals. Assembling datasets that contain seismic and infrasound signals generated by a single source can provide a better understanding of specific source processes. The successful...

141. Correlating shear content in seismic source functions to scaled depth-of burial for a series of buried chemical explosions (O2.3-141)

T2.3 - Seismoacoustic Sources in Theory and Practice

Oral

We have previously used data from the Source Physics Experiment (SPE) to relate evidence of joint slip in the near field to the yield-scaled depth-of-burial (SDOB) of buried chemical explosions in granite. A sudden surge in tangential velocity occurs in velocity records just after the passage of the peak radial shock for moderately overburied tests. This surge does not appear for nominal SDOB...
