Abstract Large earthquakes are among the most dangerous natural disasters with potentially devastating effects on society and infrastructure across globe. In order to better understand earthquakes, research in active tectonics aims at quantifying crustal deformation throughout fault’s earthquake cycles by studying geomorphic stratigraphic evidence of recent past earthquakes. The underlying assu...

Abstract Volcanoes switching from quiescence to eruption shortly after catastrophic earthquakes have raised interest for volcanic triggering and the influence of on activity. Its already active systems especially at open-vent volcanoes is more difficult apprehend. A number recent observations suggest an tectonic Popocatépetl’s activity, importance which remains unknown. To further investigate t...

the tajan river is one of the most important rivers in the north of iran. it seems that in respect of its meander design and pattern, passing over the block's fault and deviations along its way, it's influenced with active neotectonically movements in the region. although being meander in rivers, in the level of a flood water field with very low gradient, isn't unexpected but exi...
