The ongoing, dramatic increase in seismicity in the central United States that began in 2009 is believed to be the result of injection-induced seismicity (Ellsworth, 2013). Although the basic mechanism for activation of slip on a fault by subsurface fluid injection is well established (Healy et al., 1968; Raleigh et al., 1976; Nicholson and Wesson, 1992; McGarr et al., 2002; Ellsworth, 2013), t...

â  abstract geographical placement of iran especially azerbaijan area in highly strips and alpine-himalayan seismic, causes the earthquakes and their damages as inevitable facts in our country. for this reason, recognition of parameters affecting occurrence of earthquakes and development of new and suitable methods for prediction is necessary in azerbaijan region. analyzing the complex spatio-t...

We present evidence that at least two of the three 1811–1812 New Madrid, central United States, mainshocks and the 1886 Charleston, South Carolina, earthquake triggered earthquakes at regional distances. In addition to previously published evidence for triggered earthquakes in the northern Kentucky/southern Ohio region in 1812, we present evidence suggesting that triggered events might have occ...
