“…In the area of the Bucaramanga nest, the presence of dams has raised the question of the possibility of induced seismicity; however, up-to-date there is no evidence of an increase in seismicity that could be related to the dam activity. According to Simpson et al, (1988), the seismicity caused by the activity of dams would be limited to shallow events, approximately up to about 30 km. Most earthquakes in the Bucaramanga nest are of intermediate-depth (> 70 km, e.g.…”

We present the first systematic exploration of earth tides-seismicity correlation in northwestern South America, with a special emphasis in Colombia. For this purpose, we use a dataset of ~167,000 earthquakes, gathered by the Colombian Seismological Network between 1993 and 2017. Most of the events are intermediate-depth earthquakes from the Bucaramanga seismic nest and the Cauca seismic cluster. For this purpose, we implemented a novel approach for the calculation of tidal phases that considers the relative positions of the Earth-Moon-Sun system at the time of the events. After applying the standard Schuster test to the whole dataset and to several earthquake samples (classified by time, location, magnitude and depth), we found strong correlation anomalies with the diurnal and monthly components of the tide (global log(p) values around -7.0 for the diurnal constituent and -12.1 for the monthly constituent), especially for the intermediate depth events. These anomalies suggest that around 16% of the deep earthquakes in Colombia may be triggered by tides, especially when the monthly phase is between 350º-10º. We attribute our positive results, which favor the tidal-triggering hypothesis, in contrast to previous negative ones to: 1) the size of our dataset, and 2) the method we used to calculate tidal phases. Anyone willing to reproduce our results or to apply our methodology to custom datasets can use the public information system tQuakes that we developed for this work.

“…These stresses may pose significant risk associated with accelerated deformation, fault reactivation, and possible damage to reservoir seals. Regional increases in seismic activity induced by such dynamic stresses have been reported in numerous studies (e.g., Brodsky & Lajoie, 2013;Davis & Pennington, 1989;Deichmann & Giardini, 2009;Ellsworth, 2013;Frohlich, 2012;Healy et al, 1968;Holland, 2013;Horton, 2012;McGarr et al, 2015;McNamara et al, 2015;Raleigh et al, 1976;Simpson et al, 1988;Sminchak & Gupta, 2003;van der Elst et al, 2013;Walsh & Zoback, 2015;Weingarten et al, 2015;Zoback, 2012;Zoback & Gorelick, 2012). However, in the context of energy recovery, these dynamic stresses may be beneficial in enhancing permeability and have received relatively little attention.…”

We report on laboratory experiments designed to explore the fundamental processes that impact fluid permeability during drilling and fluid injection. Coupled ultrasonic and permeability measurements are presented for Westerly granite samples fractured in situ and used to illuminate the relationship between nonlinear dynamic stiffness and fracture permeability indexed via fracture aperture. We perturb the effective stress field using normal stress and pore pressure oscillations. The velocity of ultrasonic waves transmitted across the fracture is used to infer the evolution of elastic properties and the fracture nonlinearity. Changes in permeability are measured concurrently. We observe that relative changes in wave velocity and permeability, due to both normal stress and pore pressure oscillations, are correlated, such that larger drops in wave velocity (higher nonlinearity) correspond to larger increases in permeability. Our observations suggest that dynamic stressing is more likely to enhance the permeability of fractures that exhibit greater nonlinearity.

“…On land, there are many records of earthquakes caused by reservoir filling, which indicates that water loading has an effect on seismicity [84][85][86]. The same situation may occur in the ocean with the progression of sea-level rise.…”

With the rapid development of urbanization around the world, the sea-level-rise problem is gaining more and more attention in the 21st century. Sea-level rise is the result of a combination of climate-related factors, structural factors and human activities. Recent studies related to the contributions of these factors to sea-level rise are reviewed and analyzed in this paper. The results suggest that the melting of glaciers and ice sheets have contributed the most to sea-level rise and will continue to be the dominant factor in sea-level rise for the following decades. As sea-level rise becomes an increasingly serious problem, geological disasters related to sea-level rise are also gaining more attention. To better understand the effect of sea-level rise on geological disasters, relevant issues including storm surges, seawater intrusion, the loss of coastal wetland, seismicity, seismic liquefaction and submarine mass failure are further reviewed and highlighted. In response to the risks of those disasters caused by sea-level rise, some disaster mitigation measures are proposed, and in the end, the quantitative disaster assessment concept based on resilience is introduced to the coastal urban system, to assess its ability to resist and recover from geological disasters due to the sea-level rise.
