The results of near real-time monitoring of the active Kamchatka volcanoes are described. Continuous monitoring was carried out using three remote methods: 1) seismic monitoring according to automatic telemetric seismic stations; 2) visual and video observation; 3) satellite observation of the thermal anomalies and the ash clouds. Annual results of seismic activity of the Northern (Shiveluch, Kluchevskoy, Bezymianny, Krestovsky, and Ushkovsky), the Avacha (Avachinsky, and Koryaksky), the Mutnovsky-Gorely volcano groups and the Kizimen volcano are presented. 5464 earthquakes with КS=1.8–8.1 were located for the Northern volcano group, 302 earthquakes with КS=1.7–5.7 – for the Avacha volcano group, 295 earthquakes with КS=2.1–6.8 for the Mutnovsky-Gorely volcano group, 462 earthquakes with КS=2.2–8.3 for Kizimen volcano, and 165 earthquakes with КS=2.5–8.4 for Zhupanovsky volcano in 2015. Maps of epicenters, quantities of seismic energy and earthquake distribution by energy classes are given. All periods of activity were fixed and investigated by remote methods in 2015: intensive volcanic activity of the Sheveluch volcano associated with a new cone; the summit explosive-effusive eruption of the Kluchevskoy volcano in January–April; and a continuation of seismic and volcanic activity of the Zhupanovsky volcano after 56-year quite period.

. It is reported that 59 seismic stations operated in the region in 2013. In the western and eastern parts of the region, new stations equipped with Russian digital equipment UGRA were opened: Aibga, Fisht, Karaman. The seismic network recorded 1941 earthquakes and 34 explosions in industrial quarries. 37 earthquakes were felt in the settlements of the Caucasus. The maximum shaking intensity, equal to Imax=6 on the MSK-64 scale, was felt during earthquakes on April 16 at 12h26m with КР=11.8 in the settlements of Kichi-Gamri, Mamaul, Myurego of Dagestan. Swarms of weak earthquakes with КР=4–8 were recorded in the Greater So-chi, Krasnaya Polyana areas, in Kabardino-Balkaria, and in the adjacent territory of Georgia in the area of Kazbek volcano. The area of manifestation of earthquakes with intermediate hypocenter depths, which previously belonged only to the Terek-Caspian trough (the territory of the Chechen Republic) along the diagonal Benoy-Eldarov suture zone, expanded in 2013 to the southeast and advanced under the structures of the Dagestan wedge. According to the level of seismic energy released, seismicity of the territory of the North Caucasus in 2013 characterized in accordance with the scale of the seismicity level as “background low” for the period of observations from 1962 to 2013. The strongest earthquakes occur in the connection zones of the main tectonic structures.

The results of Yakutia seismicity monitoring based on data from 24 digital seismic stations are presented. 718 earthquakes with KP=7–14 were recorded. A map of epicenters and their distribution by areas of the region are given. The most active areas were the Olekma and Aldan highlands in the south, the Laptev Sea, Chersky Range and Primorsky lowland in the north-east and the Arctic part of the region. A significant decrease (10-times less) in the amount of released seismic energy was observed in comparison with this parameter for 2013.

The information about 12 digital seismic stations and monitoring equipment types and parameters is given. Maps of earthquake energy representativeness, seismic stations and epiсenters are presented. The distribution of earthquake number by energy classes and total seismic energy by six regions of North-East of Russia is given. The information about 234 events with energy classes КР=6.0–12.8 is included in the catalog. All hypocenters are located within the Earth's crust. Earthquake epicenters in Kolyma area are plotted on the tectonic zoning scheme. The strongest earthquake in 2014 with MPSP=4.5 (КР=12.8) occurred on July 4 in Kolyma area and was called Elgenskoe II. It was sensible with intensity I=4. Monitoring in 2014 showed decrease of seismic activity in Okhotsk sea area and its increase in the Kolyma. Spatially, all the earthquakes of the North-East of Russia are traditionally concentrated within the large seismogenic zones: the Chersky, the North Okhotsk and the Trans-Bering Sea.

The results of experiments on the study of the radiation characteristics of powerful vibrators and reception conditions at a number of seismic stations in the Altai-Sayan region in the range of distances of 50-450 kilometers in the problem of selecting points for active vibro-seismic monitoring are presented. It is shown that the real effective range of the CV-40 vibrator can be significantly increased by using multiple and semi-multiple harmonics. A method for assessing the applicability of stations for vibration monitoring using special programs for assessing the seismic background and seismic resonances within the boundaries of the location of seismic stations is proposed and tested.

The results of monitoring the seismicity of the territory of Yakutia, based on observations of 23 digital seismic stations, are presented. A total of 607 earthquakes were recorded. A map of epicentres was compiled and their location was given in seismically active regions. The most active areas are Olekminsk in the south, Verkhoyansk and Chersky Ridge in the northeast and the Arctic part of the region. A significant decrease (19 times) in the amount of released seismic energy continued in comparison to its level in 2014. Instrumental and macroseismic data, focal mechanisms and seismotectonic connections are analyzed. The characteristics of the shaking South-Verkhoyansk earthquake occurring at the junction of the Verkhoyansk and Sette-Daban Ridges are considered.

In 2014, a network of 35 digital seismic stations of Azerbaijan continued to operate unchanged, while significant changes occurred in the work of analog stations – they were completely stopped in May 2014. The set of parameters determined for estimation of the earthquake magnitude decreased – determination of MPVA magnitude and KP energy class ceased. Only the local magnitude ML Azr is measured, which is converted then into energy class K. The total number of earthquakes recorded by Azerbaijan network of seismic stations amounted to 5754, but the Azerbaijan earthquake catalog published in the Appendix to this article contains 135 of them with ML Azr3.0 only. An increase in seismic activity in the study area was noted. This is expressed in increase in 2014 of number of representative earthquakes (K≥9) compared with both their number in 2013 and the average annual value for 1993–2013. The seismic energy released in 2014, after its reduced values in 2013, approached the background level. In 2014, the most significant seismic event on the territory of the Republic was the February 10 earthquake with ML Azr=5.7 and intensity in the epicenter of I0=6.
