We thank Rastogi for pointing out a number of factual errors in our article, and welcome this opportunity to correct several scientific misunderstandings that have crept into his manuscript. Rastogi is in agreement with our statements and conclusions concerning the seismicity in the Jaitapur region that: (a) no significant M > 6 earthquakes have been recorded by seismographs located within 50 k...

14C-dated Holocene coastal uplift, conventional and satellite geodetic measurements, and coseismic and aseismic fault slip reveal the pattern of distributed deformation at Taiwan resulting from convergence between the Philippine Sea plate and Eurasia; as in other subduction orogenic settings, the locus of strain release and accumulation is strongly influenced by changes in fault geometry across...

Displacement-based seismic design and assessment procedures require as key input parameter estimates of displacement capacities of the critical elements. The displacement capacities of unreinforced masonry (URM) walls are typically determined by means of quasistatic cyclic tests. This paper shows that for URM walls failing in shear the number of applied cycles in quasi-static cyclic tests influ...

The June 28, 1992, Mw 7.3 Landers earthquake occurred in the southeastern Mojave Desert, California. Over 10,000 aftershocks of the earthquake were recorded by the Caltech-USGS Southern California Seismic Network (SCSN) in 1992. To investigate the relationship between complexities in the crustal structure and variations in seismicity, we have used a tomographic method to invert 145,098 P wave a...

Australia is in a unique position globally being a continent where Mw7.0 events can occur in the Craton, and potentially similar large events in the non-Craton areas, however only a recorded history of around 150-200 years or less exists in most locations. Although a lowmoderate seismicity country, many locations have already experienced damaging earthquakes. The recent earthquake hazard maps i...

Since 2006 wastewater has been injected below the Val d'Agri Quaternary basin, the largest on-land oilfield in Europe, inducing micro-seismicity in the proximity of a high-rate injection well. In this study, we have the rare opportunity to revise a massive set of 2D/3D seismic and deep borehole data in order to investigate the relationship between the active faults that bound the basin and the ...

Numerical models including one or more faults in a rheologically stratified lithosphere show that climate-induced variations in ice and water volumes on Earth's surface considerably affect the slip evolution of both thrust and normal faults. In general, the slip rate and hence the seismicity of a fault decreases during loading and increases during unloading. Here, we present several case studie...

Over four months of continuously recorded microearthquake data acquired at Cold Lake, Canada was analyzed using advanced algorithms for micro-earthquake location and subsurface imaging. Robust determination of the spatial, temporal and magnitude distribution of seismicity is the first step towards understanding the relationship between the stress perturbations caused by the Cyclic Steam Stimula...

This paper refers to the present state of historical buildings situated in the Karviná and Ostrava region and also to the problems of these buildings caused first of all by surface vibrations generated by mining-induced seismicity in the Karviná region and by technical seismicity caused by industrial activities and transportation in the Ostrava region. Designing of earthquake-resistant structur...

Fluid injection into rocks is increasingly used for energy extraction and for fluid wastes disposal, and can trigger/induce small- to medium-scale seismicity. Fluctuations in pore fluid pressure may also be associated with natural seismicity. The energy release in anthropogenically induced seismicity is sensitive to amount and pressure of fluid injected, through the way that seismic moment rele...
