News of the Laboratory of Deep Magnetotelluric Studies (LDMS)

In October and November,2016, the LDMS staff fulfilled the field works by the method of magnetotelluric soundings on the Kentor site (on 34 points of Central and East profiles) and in surroundings of Noorus settlement. The registration of MT-field was performed with the help of Phoenix MTU-5 and MTU-5A measuring complexes. Field works were conducted at a height of 2000 m above sea level. Time of field recording was 14 – 18 hours. The MT data in a range from 0,001 to 3000 sek. were obtained. The works were complicated by poor weather conditions (thunder storms, rains, snow and low temperature).

In the third decade of October the works on Ukok profile in the surroundings of Kochkor village were conducted. MT soundings were carried out on 7 points of observation: six points were in the center of profile with 150 – 200 m step, and the sevenths points is stationary and time of field recording was 68 hours.

News of GMTS

In August, 2016, the Group of Magnetotelluric Soundings performed the field works under the method of magnetotelluric soundings in Kochkor depression along Ukok profile, in the surroundings of Kochkor village. MT soundings along Ukok profile were carried out on 22 points of observation by means of three field teams. Registration of MT-field was performed with the help of measurement complex Phoenix MTU-5 and MTU-5A. Field works were conducted at a height of 2000 m above sea level. Time of field recording was 14 – 18 hours. The MT data in a range from 0,001 to 3000 sek. were obtained.

Installation of additional sites of regional GPS network in area of Mountains Jumgal-Too

According to the results of scientific research works of 2015 for a large part of the territory of the Central Tien Shan there was obtained general correlation in the distribution velocity of the summary horizontal deformation on GPS and seismologic data for the observation period 1998-2014.
At that, the reduced velocities of near-surface dilatancy and increase in deformation velocities in seismic active layer of the Earth’s crust were fixed in area of Mountains Jumgal-Too (Fig. 1).

Figure 1. The distribution of total horizontal deformation velocity (dilatancy) for the near-surface part of the Earth’s crust according to GPS data.

Field research under GMTS method

On 11 – 12 of July, 2016, the MTS Group returned to Research Station base after important field works carried out on Dergochko and Karabuk profiles (Issyk _Kul and Naryn regions). Works were performed with the help of Phoenix MTU-5 and MTU-5A measurement complexes. On Dergochko profile (The Issyk-Kul, Naryn Region) works were performed under GMTS method. Two field groups carried out works on 4 observation stations where the registration of MT field long-period variations required long stay. Works were performed at the height from 2100 to 3200 meters above sea level. Time of observations on each point made three days as the result of which the MT data from 0,01 to 10000 sec. were obtained. Works on measuring station launching and MT-field registration were complicated by unfavorable weather conditions (rain, snow, fall of temperature).
