 | Identification of seismic events detected globally at regional distances between the source and the sensor requires a clear physical understanding of the different types of seismic sources including mining explosions, rock bursts, mine collapse, as well as small, shallow earthquakes. This research studies constraint of the operative physical processes in the source region and linkage to the generation of seismic waveforms with emphasis on investigating a number of modern visualization ... |

| This report documents two efforts undertaken during the past 12 months. The first describes a combined near-source/regional monitoring of a series of mining blasts in Southern Russia. The second contribution describes a theoretical investigation of nuclear explosion source model resolution using near-source seismic data in a nonlinear inversion scheme.

| Experimentally produced surface waves at high frequencies (5-50 Hz) and short source-receiver distances (5-100 m) are utilized in the determination of shallow shear structures in geological materials. This procedure is shown to provide a high resolution picture of these shallow materials which may be of interest to the engineering and environmental community. Love waves are generated by the Sh source, SWIG, developed under this contract. Rayleigh waves are produced by ... |

| Work in the past reporting period has been focused in four areas all related to our task of shallow geological site characterization using seismic waves. The first area of emphasis is documented in, Comparison of Sources for Shallow Seismic Imaging: Radiation, Energy and Bandwidth by Hayward and Pearson. This paper contrasts a variety of shallow seismic sources for P and S waves. The second paper, Characterization of the Shallow Weathered ... |

| An important application of high resolution geophysical exploration is the interpretation of strong ground motions from chemical and nuclear explosions. High dynamic range data acquisition systems which are capable of acquiring multiple channels of data are necessary. Ground motion sensors, data analysis microsystem, and field enclosures were supported under this grant. Spanning ground motions from the low level exploration environment to the strong levels next to explosive sources was done ... |

|
| An experimental technique for characterizing the seismic source from chemical explosions in different geological material is presented. The specific example of an explosion in alluvium is given. The importance of a complete seismic site characterization prior to the experiment is emphasized. This characterization must include determination of both compressional and shear properties at the test site. Keywords: Seismology; Explosion source; Moment tensors; Inversion; Seismic modeling.

|
 | Work in four areas is reported. The first deals with the design and implementation small scale chemical explosions for the purposes of constraining the physical characteristics of the equivalent elastic source. The second major area of work is the experimental quantification of the effect of source depth in generating body and surface waves in the near-field. The third contribution reports attempts to determine the effect of scattering on near-field waveforms. ... |

|
| This report summarizes work accomplished by the Air Force Weapons Laboratory during the period May 1981 to April 1982. The purpose of this work has been to focus on seismic source characterizations of explosive sources. Specifically, we have investigated the usefulness of the moment tensor representation in modeling near-field recordings of contained nuclear explosions. Extension of the source representation to surface explosions utilizing the zeroth order moment has also been ... |
