“…Detailed studies by Hollister and Weimer [1] and Healy et al [9] confirmed the causal observations of Evans [10] that the seismic events were induced by the waste fluid injection. Similar relations between local seismicity and fluid injection were likewise observed at the Rangely Oil Field, Colorado by Pakiser et al [11], Healy et al [12] and Gibbs et al [13], and in the Los Angeles basin by Teng et al [14].…”

The study of fault slip in response to fluid injection offers a means to understand the complex hydromechanical behavior of shale gas and oil reservoir systems during hydraulic fracturing operations, together with the induced seismicity, and corresponding mitigation measures, arising from such events. In this paper, a series of numerical simulations are performed to investigate the relationship between hydraulic fracturing i.e. fluid injection and the response of a naturally fractured rock mass to transient fluid pressures. The analysis is carried out using the discontinuum-based distinct-element program UDEC assuming a fracture flow system. The conceptual reservoir model consists of a critically stressed fault plane and the surrounding rock mass containing planes of weakness, for which a hydraulic fracture is numerically simulated and the response modeled using a transient, coupled hydro-mechanical solution. The results demonstrate the influence of fluid diffusion generated by the fracing fluid after shut-in on the triggering of fault slip. The simulation is then used to interpret the associated seismic events and their relationship to the injections and shut-in pressures, and to estimate the maximum magnitude of the induced seismic event.

“…The results of this paper do not appear to be directly applicable to the Rangely earthquake experiments [Healy et al, 1972]. This is not surprising, since the results apply only to conditions within the reservoir before appreciable fault movement takes place.…”

“…Apparently man-made earthquakes associated with fluid injection have called attention to the effects of fluid pressure on rock failure [Healy et al, 1968[Healy et al, , 1972Sykes et al, 1973]. This behavior can be easily demonstrated in the laboratory [Jaeger and Cook, 1969;Handin et al, 1963] and can be explained by using the concept of effective stress [Terzaghi and Peck, 1948;Nur and Byedee, 1971 ].…”

The effects of variations in fluid pressure in large, thin, horizontal aquifers and reservoirs are analyzed by assuming a condition of no horizontal strain. The results indicate that the difference in induced effective horizontal and vertical stresses, coupled with the initial stresses, determines the stability to induced faulting. Conditions characterized by thrust faulting are found to be the least stable, and those characterized by normal faulting to be the most stable. The stability to induced faulting is shown to decrease with increasing values of the intermediate effective principal stress in regions characterized by normal and wrench faulting. However, this effect is not present in regions characterized by thrust faulting.

“…1). This made the 1999 Taiwan earthquake distinct and not unlike a few other major earthquakes, such as the 1857 Fort Tejon and the 1906 San Francisco earthquakes (Healy et al, 1972) as well as the 1923 Kanto earthquake (Shimazaki, 1971). Obviously, the occurrence of these earthquakes did not conform with the popular notion that the more microearthquakes there are, the greater is the risk of a strong earthquake.…”

The 1999 Taiwan Earthquake: A Proposed Stress-Focusing, Heel-Shaped Model

Stress focusing in a proposed heel-shaped model reasonably explains the occurrence of the largest onland earthquake (M W 7.6) in Taiwan's history. The epicenter of the mainshock was located in a low-seismicity block, where, historically, large earthquakes have not been documented for the past century. Spatial variations in crustal deformation reported in Global Positioning System surveys suggest that the crustal strength in the low-seismicity block was stronger than in the surrounding area. Since the low-seismicity block, which roughly coincides with the northern part of the Peikang High, is defined by a convex curve, stress partitioning or reorientation might well have taken place along the convex boundary; it then likely stored a lot of strain energy before eventually failing. The low-seismicity block with strong crust characteristics was finally overcome by stress focusing, resulting in the generation of the 921 Chi-Chi earthquake near the focus of the low-seismicity block, where a cluster of earthquakes had occasionally occurred during the past decade. Significant surface ruptures with vertical offset ranging from 2 to 8 m, primarily along the Chelungpu fault, were restricted to within the low-seismicity block. In short, when a low-seismicity block with small velocity fields of crustal deformation is identified in an active foreland belt, there should be a greater risk of a larger earthquake to release energy that accumulates in the strong crust. This finding provides some useful insight with which to evaluate potential earthquakes in Taiwan and other convergent zones.
