The most general source of highfrequency seismic motions must be a linear combination of a double couple and another source called the compensated linearvector dipole. A radiation pattern of amplitudes of first motions on the focal sphere cannot be uniquely
2004-3-15We illustrate its applicability using three case studies a four-machine transfer line a vehicle assembly line and an open-pit mining conveyor system. The results confirm that the machines with greater unavailability factors are not necessarily the most important for the efficiency of the production line as it is the case when no
The fourth edition of Physics of the Earth maintains the original philosophy of this classic graduate textbook on fundamental solid earth geophysics while being completely revised updated and restructured into a more modular format to make individual topics even more accessible

2011-11-16Microseisms or microseismic events Small bursts of seismic energy generated by shear slippages along planes of weakness in the reservoir and surrounding layers which are induced by changes in stress and pore pressure around the hydraulic fracture. These microseisms are extremely small and sensitive receiver systems are required

Multiple methods and softwares have been used to conduct numerical simulations and make predictions on the energy resources e.g. artificial neural networks ant tracking algorithms petrophysical logging and microseisms 35363738.The ant tracking algorithm can be applied to detect small faults but it is difficult to extract detailed formation of the fractures due to the extremely low

Moment magnitudes of microseisms generally range from -3 to 2 on this logarithmic scale they correspond to extremely low energy levels that are not felt by humans. Just above an event of magnitude 3 is equivalent to a truck vibration more or less the limit of human perception

In this study we present a method for the simultaneous recovery of the three source parameters origin time hypocentre location and seismic moment tensor. This waveform fitting method is a modification of the Block Orthogonal Matching Pursuit BOMP from sparse representation theory Eldar et al. 2010
2020-5-17Other topics are indexed using environment or sedimentation terms. Economic geology 26-29 papers which focus on economics rather than geology of the commodity are designated with a B code e.g. 26B-29B. Articles with a commodity economics focus are rarely covered unless they occur with another topic of interest
The goal of this study is to apply the suggested approach in a further context. We focus on automatic recognition of patterns on different timescales using longer continuous records. In particular we consider volcano-seismic signals and temporal patterns in ambient seismic vibrations Section 3 and 4
1. Introduction 2 Primarily because of two factors there has recently been an increase of interest in Earths seismic noise field. First is the recognition that ambient seismic noise can be used to image shallow Earth structure Courtland 2008.Tomographers are now able to fill in gaps created by irregularities in earthquake location and produce more uniform images of wave speed variations
Continuous monitoring of mechanical parameters determining the state of natural and man-made systems is essential in a wide range of engineering disciplines from mechanical to civil and geotechnical engineering. To be effective the monitoring response time needs to be commensurate with the characteristic time of variation of the processes being monitored e.g. from seconds as for example in
