Insights into the Aftershocks and Inter-Seismicity for Some Large Persian Earthquakes

This paper focuses on aftershocks behavior and seismicity along some co-seismic faults for large earthquakes in Iran. The data of aftershocks and seismicity roughly extracted from both the Institute of Geophysics the University of Tehran (IGUT) and International Seismological Center (ISC) catalogs. Apply some essential methods on 43 large earthquakes data; like the depth, magnitude as well as t...

Secondary Aftershocks and Their Importance for Aftershock Forecasting

The potential locations of aftershocks, which can be large and damaging, are often forecast by calculating where the mainshock increased stress. We find, however, that the mainshock-induced stress field is often rapidly altered by aftershock-induced stresses. We find that the percentage of aftershocks that are secondary aftershocks, or aftershocks triggered by previous aftershocks, increases wi...

Some Aspects about Seismology of 2012 August 11 Ahar-Vaezaghan (Azarbayjan, NW of Persia) Earthquakes Sequences

In 2012 August 11 (12:23 UTC) a moderate earthquake with MW=6.4 (USGS) occurred between Ahar and Varzaghan towns in Azarbayjan Province at northwest of Iran. After eleven minutes another earthquake shook the area with MW=6.2 (USGS). These consecutive earthquakes followed by intensive sequences of aftershocks whereas the strongest one had MW=5.3 (USGS). In data processing including depth modific...
