Seismic Impact of Industrial Blasts in Western Siberia and Induced Seismicity

Seismic Instruments, 2019
Based on data from regional seismic networks and experiments employing temporary networks, the degree of seismic impact of industrial blasts in southwestern Siberia is studied. Since the blasts at all mining enterprises were ripple-fired shots, magnitudes are studied proceeding from the total explosive charge and the dependence of magnitudes on the ...

Impact Seismic Techniques: ABSTRACT

AAPG Bulletin, 1963
During the past few years there has been a general increase in the use of Impact Seismic Techniques to obtain geophysical data. In the extension and development of these techniques there has been some divergence from the original classic McCollum 2-patch technique.

The Impact of Sub-Sea Seismic

Proceedings, 1995
The sub-sea sensing technology has been around for some time. The recently developed SUMIC (sub-sea) technique [1] has pointed out some new applications in exploration and production. This will have an impact on how marine seismic acquisition and seismic data analysis are performed.

Impact of using updated seismic information on seismic hazard in western Canada

Canadian Journal of Civil Engineering, 2010
This study provides a preliminary assessment of the impact of new seismological information on the existing seismic hazard model, as implemented in the 2005 National building code of Canada (NBCC); this seismic hazard model was actually developed in the early 1990s, and thus there is significant new information available in the literature since then.

Impact of Seismic Surveys on Marine Life

SPE International Conference on Health, Safety and Environment in Oil and Gas Exploration and Production, 2000
Abstract During the last decade significant research has been performed on the possible impact of seismic surveys on marine life. Both fish and marine mammals have been studied. None of the studies have documented direct damage caused by the signals, but there may be a temporary behavior change out to a distance of a few kilometers.

Economic Impact of Seismic Events: Modeling

2014
People live in earthquake-prone areas. Tectonically active landscapes may have produced greater biodiversity, more food and water, through disturbed drainage patterns and wetland creation. Nevertheless over the last 200 years, global population growth has increasingly placed pressure on human settlements and resulted in the proliferation of urban areas

Seismic impact between adjacent torsionally coupled buildings

Soil Dynamics and Earthquake Engineering, 2019
Abstract The problem of seismic impact between torsionally coupled multi story moment frame buildings is investigated in this paper. Five pairs of adjacent structures spaced at various separation distances are considered. The buildings are 4–10 stories in height. Although a common plan being symmetric with regard to lateral stiffness is considered, a

Seismic attribute analysis of Chicxulub impact crater

Acta Geophysica, 2020
Chicxulub crater formed ~ 66 Ma ago by an asteroid impact on the Yucatan platform in the southern Gulf of Mexico. The crater has a ~ 200 km rim diameter and has been covered by carbonate sediments up to ~ 1.1 km thick in the central zone. Previous studies have identified the structure and major crater units through geophysical models from seismic ...

Dynamics of seismic impacts in base-isolated buildings

Earthquake Engineering & Structural Dynamics, 1997
A systematic study is made of the effects of seismic impacts between the base of an isolated building and the surrounding retaining wall. The analysis is performed without using gap elements or assuming values of the coefficient of restitution and the duration of impact.

Quantifying the Economic Impact of 4D Seismic

Proceedings of SPE Annual Technical Conference and Exhibition, 2000
Abstract Time-lapse 3D, or 4D, seismic has been looked at by the industry for over a decade, with a growing number of successful cases being reported in the literature. Two of the most recent 4D case studies reporting success are Draugen in the Norwegian North Sea and Gannet-C on the UK continental shelf.
