In 2014, a seismic monitoring system, restored with the participation of the Swiss government, continued to operate in Tajikistan. Seven digital stations Trident+Trillium-40 devices, provide registration of events located in Tajikistan and hundreds of kilometers beyond. This network recorded 5306 earthquakes with КР=8.6–14.5, of which 4308 are deep-focus Pamir-Hindu Kush earthquakes with h=70–270 km and 998 are shal-low, scattered throughout the territory. The total seismic energy released in the sources of all earthquakes amounted to Е~6.61014 J. Within the borders of the Republic, the most powerful earthquake (with КР=13.3) was on September 13. The earthquake located in the southern spurs of the RushanRange at the end of the system of dual Karakul-Sarez faults dividing the Pamirs into Western and Eastern parts. It was felt with an intensity of Ii=4–5 in Khorog and Roshtkal, Ii=4in Rushan and on the lake Sarez. Shocks with Ii=4–5 from the November 1 earthquake with KP=12.1 were also felt in Rogun, at the site of Rogun hydropower plant under construction. The maximum deepest earthquake (КР=14.5, Mw=5.4, h=200 km) occurred on June 14 in the Afghan subzone. Due to the great depth, the area of its perceptibility Ii=3 amounted to 220 thousand km2 in Tajikistan, Afghanistan, Pakistan and Kyrgyzstan. However,in general the seismic process in the Republic proceeded in the background.
