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).

Monitoring observations, Laboratory of Deep Magnetotelluric Studies (LDMS)

Further to monitoring observations that have been accomplished by natural electromagnetic field method (NEFM) on the Bishkek Geodynamic Proving Ground (Kentor miniground) since 2012, 3 teams of Group of Magnetotelluric Sounding (GMTS) fulfilled the sounding by AMTS and MTS methods in the period from 16 to 31 May, 2016.

MT observations were carried out on the profiles “Central” (11 points) and "East" (18 points). On the “East” profile (9 – 18 points) works in AMT mode were performed as well. As a result of observations the magnetotelluric curves in the range of periods from 0,01 to 3000 seconds have been received.
