Evidence for Caribbean Plate Subduction Beneath the Isthmus of Panama and Implications for Subduction Initiation and the Closure of the Central American Isthmus During the Miocene

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The evolution of the Isthmus of Panama during the Miocene resulted in climatic shifts leading to global cooling, reorganization of ocean currents, and regional mass extinctions. The causes of this change in ocean circulation between ∼15 and 5 Ma have been debated, with various tectonic scenarios being proposed as explanations for this event ...

Seismic monitoring network for induced seismicity in the Netherlands

EAGE GeoTech 2021 First EAGE Workshop on Induced Seismicity, 2021
The seismic monitoring network in the Netherlands consists of a dense network of shallow borehole arrays (200 m depth) and surface accelerometers in the Groningen region and a sparser network in the rest of the country. The dense network in Groningen is targeted at induced seismicity due to gas extraction.

Application of seismic tomography to induced seismicity investigations

Proceedings of Rock Mechanics in Petroleum Engineering, 1994
Abstract Two case studies are presented, which highlight the potential application of seismic velocity imaging to induced seismicity investigations. Velocity images may be produced using data currently recorded with seismic monitoring arrays.

Reservoir-induced Seismicity in China [PDF]

open access: possiblePure and Applied Geophysics, 1998
A review of case histories of reservoir-induced seismicity (RIS) in China shows that it mainly occurs in granitic and karst terranes. Seismicity in granitic terranes is mainly associated with pore pressure diffusion whereas in karst terranes the chemical effect of water appears to play a major role in triggering RIS.

Induced seismicity in Canada

Engineering Geology, 1976
Abstract The annual and cumulative catalogues of Canadian earthquakes prepared by the Department of Energy, Mines and Resources, are critically examined to determine if they contain examples of induced seismic activity caused by fluid injection in oil fields, by the impounding of water in large reservoirs or by mining.

Induced seismicity in engineering [PDF]

open access: possibleGeological Society, London, Engineering Geology Special Publications, 1988
Abstract A review is made of the main areas of engineering and mining activities, which give rise to induced seismicity in the rock mass. These include the occurrences of rock bursts following the failure of the rock mass in highly stressed areas during mining operations, seismic activity due to pumping operations in geothermal, waste ...

Probabilistic Seismic Hazard Analysis for Induced Seismicity

2014
Probabilistic Seismic Hazard Analysis is currently the most common approach to seismic hazard analysis. For application to induced seismicity, a major challenge is the fact that the hazard is inherently non-stationary. In this paper we describe the theoretical extension of PSHA to a non-stationary context.

Seismic Hazard and Hydraulic Fracture-induced Seismicity

Proceedings, 2015
Traditionally, to relate the seismic hazard potential in seismically active areas, empirical ground motion prediction equations (EGMPE) are used to relate event parameters like magnitude and location to site characteristics such as peak ground acceleration (PGA) or peak ground velocity (PGV) which tend to be how building codes are parametrized.
