“…Numerous paradigms which aim to further refine Sykes' [1978] reactivation hypothesis have been proposed [Costain et al, 1987;Johnston and Kanter, 1990;Sykes, 1978;Wesnousky, 1980], yet little consensus has emerged as to the more specific causes acting to localize and trigger such activity, nor whether ongoing seismicity is associated with other modes of lithospheric deformation. Much of the research on intraplate seismicity in SCRs has focused on the New Madrid Seismic Zone (NMSZ) in the central United States.…”

[1] The Flinders Ranges form one of the most seismically active zones within the Australian continent with seismogenic strain rates over the last 30 years of $10 À16 s À1 . Active deformation in the region reflects late Neogene increases in stress levels in the Indo-Australian plate as a response to increased plate boundary forcing from collision zones with the neighboring Asian and Pacific plates. Geological and geophysical observations suggest two modes of active deformation in operation in the Flinders Ranges over the last several million years: (1) . Numerical models are developed to explore the contribution of each of these deformation modes to the observed geophysical signals. An elastic mode of deformation is suggested by a distinctive longwavelength positive correlation between gravity and topography in which the Flinders Ranges are bordered by anomalous topographic and gravity lows, now occupied by playa-lake systems, centered some 50 km outboard of range-bounding faults. Numerical models show that flexural instabilities localized by vertical loads arising from older tectonic structuring produce a first-order match with observed topography and gravity. Numerical models are also used to illustrate how the localized failure evident in the contemporary seismicity and Quaternary faulting record within the Flinders Ranges reflects thermal weakening associated with extraordinary concentrations of heat producing elements in the crust, as reflected in modern-day heat flows of $90 mW m À2 .

“…In addition to this secular motion, strong seasonal variations in the seismicity have been reported , with a number of events about 30% higher in the winter. Similar seasonal variations have been observed in various contexts and related to factors such as snow load or variations of the water level (Costain et al 1987;Heki 2003;Saar and Manga 2003).…”

“…Such effects can increase tectonic stress, which exceeds the rainfall amounts when an earthquake occurs. Previously was pointed the role of water on the generation of intraplate seismicity by Costain et al (1987). Hainzl et al (2006) have found the clear evidence that pore pressure changes induced by rainfall are able to trigger earthquake activity even at surficial depth via the mechanism of fluid diffusion.…”

Blocking as an interruption of the climatological storm tracks means an extreme disturbance in the synoptic scale of atmospheric circulation. In this study, we aimed to describe the main role of atmospheric blocking on the earthquake prediction in the southern Iran. We gathered the subjective evidences of a block generation during April 5-9, 2013, which was clearly identified by anomalous data of geopotential height, air temperature, vertical velocity, rainfall rate and latent heat flux. Analysis of geopotential heights at the 500 and 300 hPa levels revealed that there was a dipole split-flow block with associated of a remarkable low-pressure anomaly (-76 m), which has established over southern Iran during April 5-9, 2013. This low pressure into three temporal sequences has influenced three epicenters of upcoming earthquake swarms in south parts of Iran during April and May 2013. Hence, we detected an atmosphericlithospheric cycle as a climatic conceptual model that describes the chain of the blocking-associated rainfall, preceding rainfall-triggered seismic stress, cyclogenesis, thunderstorm and subsequent stress-induced seismicity. We claimed that the blocking-associated anomalies together with the persistence of low pressure could be the earthquake precursors within 3-33 days before the main seismic shocks in Iran.
