Large earthquakes that have occurred along the North Anatolian Fault (NAF) were analysed to elaborate time frame of future large near İstanbul. The historical earthquake catalog was compiled covered 1 nearly complete and 2 fully failures NAF between 1250 2000 AD. These data used investigate space-time systematics M ≥ 7.0 earthquakes. catalogue identified an east-to-west decelerating domino-like...

damavand is a large dormant stratovolcano in the alborz mountains of northern iran located in one of the most populous provinces, which could be adversely affected by tephra fall from damavand. the youngest known eruption is a lava flow on the western flanks with an age of 7.3 ka. the volcanic products are predominantly porphyritic trachyandesite. three major young pumice deposits, named here a...

the alborz mountains, as a folded and faulting region, is the northern region of crust shortening in iran. dominant mechanism (harvard, 2002) of alborz earthquakes is left-lateral strick-slip paralleled to the range. east alborz is one of the active regions that plays a significant role in the tectonics of its neighbors like south casbin basin. regarding the geological maps of the area, the fau...

We have successfully detected widely distributed ground displacements for the 2015 Gorkha earthquake by applying a ScanSAR-based interferometry analysis of Advanced Land Observing Satellite 2 (ALOS-2) L-band data. A major displacement area extends with a length of about 160 km in the east-west direction, and the most concentrated crustal deformation with ground displacement exceeding 1 m is loc...

maragheh-bonab active cultivated plain is located in south east of east azarbaijan and consists of valuable groundwater resources. maragheh industrial park is nearly located in the recharge area of this plain. kaveh soda and paper mill factories that are located in this park produce high volume of wastewater is continually recharged in the plain. in this article, the effect of industrial wastew...

hershfield method is commonly used for computing probable maximum precipitation (pmp) in most parts of the world for which the frequency factor (km) is considered to be 15 for computing 24-h pmp (pmp24). this value may not be suitable for different stations under different climatic conditions. in 1986 the world meteorological organization standardized the hershfield method and introduced the re...

Retrospective predictions of seasonal hurricane activity in the Atlantic and east Pacific are generated using an atmospheric model with 50-km horizontal resolution by simply persisting sea surface temperature (SST) anomalies from June through the hurricane season. Using an ensemble of 5 realizations for each year between 1982 and 2008, the correlations of the model mean predictions with observa...
