Inversion of seismic source parameters for weak mining-induced and natural earthquakes
… inversion scheme to derive point and finite source parameters for weak earthquakes, here intended with the unusual meaning of earthquakes with magnitudes at the limit or below the bottom magnitude threshold of standard source inversion routines. The adopted inversion approaches entirely rely …

Apparent Stress Estimates of Seismic Events Associated with Underground Mining Operations in Sedimentary Rock Units: Implications for Improving Underground Roof Collapse Warning Systems
We analyze recordings of seismic events induced by underground mining operations at the Moonee Colliery, located in Australia, and at the Springfield Pike Limestone Quarry, located in the United States. The data were recorded underground in the vicinity of active mining operations and were …

Numerical Modelling of Seismic Activity at Tabular Orebody Mines in South Africa using the Boundary Element Method
… are generally considered to have the highest seismic hazard in the world, and large seismic events at these mines often produce strong ground vibrations that pose risks of damage to mining excavations, injury to mineworkers and even loss of life. Although most underground mines in South Africa …

Decoding Seismic Hazard Enigmas via Next-Generation Paleoseismic Analyses: With Application to the Cascadia Subduction Zone and Beyond
… are often insufficient to provide inputs to seismic-hazard analyses (i.e., fault locations and magnitude-frequency relations) or to inform ground-motion predictions for certain seismic sources. As a result, analyses of macroseismic evidence (e.g., landslides, liquefaction, and felt …

Geophysical signatures of crack initiation and growth in rocks under uniaxial compression
… in the field of seismology, in natural resource extraction, different rock-breaking processes such as drilling and blasting, and in geological investigations. In order to investigate and predict the rock behavior in the above-mentioned practical situations, it is essential to understand …

Shallow and deep deformation in northern Apennines region using seismological data
… the shallower deformation has been studied using seismic moment tensors information. For our purpose we used the methods described in Arvidsson and Ekstrom (1998) that allowing the use in the inversion of surface waves [and not only of the body waves as the Centroid Moment Tensor (Dziewonski et …

Investigation of the Pre to Post Peak Strength State and Behaviour of Confined Rock Masses Using Mine Induced Microseismicity
… occurs. Associated with this failure are microseismic events, which can be used to give an indication of the strength state of the rock mass. Based on an analogy to laboratory testing of intact rock and measurement of acoustic emissions, the microseismicity can be used to identify, fracture …
