A novel approach is presented for fast generation of synthetic seismograms due to microseismic events, using heterogeneous marine velocity models. The partial differential equations (PDEs) for the 3D elastic wave equation have been numerically solved using the Fourier domain pseudo-spectral method which is parallelizable on the graphics processing unit (GPU) cards, thus making it faster compared to traditional CPU based computing platforms. Due to computationally expensive forward simulation of large geological models, several combinations of individual synthetic seismic traces are used for specified microseismic event locations, in order to simulate the effect of realistic microseismic activity patterns in the subsurface. We here explore the patterns generated by few hundreds of microseismic events with different source mechanisms using various combinations, both in event amplitudes and origin times, using the simulated pressure and three component particle velocity fields via 1D, 2D and 3D seismic visualizations.

Business model innovation for sustainability: towards a unified perspective for creation of sustainable business models Evans, S; Vladimirova, D; Holgado, M; et al. (Wiley for ERP Environment, 5 April 2017)Business model innovation has seen a recent surge in academic research and business practice. Changes to business models are recognised as a fundamental approach to realise innovations for sustainability. However little ...
Silk, MJ; Croft, DP; Delahay, RJ; et al. (Wiley for British Ecological Society, 18 April 2017)Host social structure is fundamental to how infections spread and persist, and so the statistical modelling of static and dynamic social networks provides an invaluable tool to parameterise realistic epidemiological models. ...
Idris, I.; Biktashev, V. N. (American Physical Society, 1 January 2007)We consider the problem of initiation of propagating waves in a one-dimensional excitable fiber. In the FitzHugh-Nagumo theory, the key role is played by "critical nucleus" and "critical pulse" solutions whose (center-) ...
