We present new seismicity images based on a two‐year seismic deployment in the Pamir and SW Tien Shan. A total of 9532 earthquakes were detected, located, rigorously assessed multistage automatic procedure utilizing state‐of‐the‐art picking algorithms, waveform cross‐correlation, multi‐event relocation. The obtained catalog provides information crustal reveals geometry internal structure Pamir‐Hindu Kush intermediate‐depth zone with improved detail resolution. relocated clearly defines at...
Utilizing seismic refraction/wide-angle reflection data from 11 approximately in-line earthquakes, 2-D P- and S-velocity models a Poisson′s ratio model of the crust uppermost mantle beneath southern Tien Shan Pamir have been derived along 400-km long main profile TIPAGE (TIen shan-PAmir GEodynamic program) project. These show that crustal thickness varies about 65.5 km close to end South through 73.6 under Lake Karakul in North Pamir, 57.7 km, 50 south northern Shan. Average P velocities are...
Abstract The Cenozoic convergence between India and Asia has created Earth's thickest crust in the Pamir‐Tibet Plateau by extreme crustal shortening. Here we study structure of Pamir western Tian Shan, adjacent margins Tajik, Tarim, Ferghana Basins, Hindu Kush, using data collected temporary seismic experiments. We derive, compare, combine independent observations from P S receiver functions. obtained Moho depth varies ~40 km below basins to a double‐normal thickness 65–75 underneath Kush. A...

We present new seismicity and focal-mechanism data for the Fergana basin surrounding mountain belts in western Kyrgyzstan from a temporary local seismic network. A total of 210 crustal earthquakes with hypocentral depths shallower than 25 km were observed during 12-month period 2009/2010. The hypocenter distribution indicates complex net seismically active structures. derived this study is mainly concentrated at edges basin, whereas rate within low. dominant tectonic feature region,...
Frequent landsliding is one of the greatest natural hazards facing inhabitants Central Asia's Fergana Basin and surrounding mountain ranges. Active tectonics in region rapidly building Tien Shan, highest ranges on Earth, extreme topographic relief promotes frequent landslide activity, which causes major losses life property. In southwestern Kyrgyzstan alone, average 10 people die seven houses are destroyed each year these sudden moving landslides.
The impacts of seismicity on the landslide activity in Kyrgyzstan have been focus our study since 2010 [Kalmetyeva et al., 2010]. As progressed [Kalmetyeva, Moldobekov, 2012, 2013; Kalmetyeva 2013, 2014], initial problem statement has revised as follows: do earthquake influence occurrence land‐ slides, and, if so, what is mechanism this influence. This paper presents results detailed analysis distribution earthquakes and landslides space time correlation with focal mechanisms (azimuth plunge...
