HE MAIN SCIENTIFIC DIRECTIONS OF THE LABORATORY:
CONTINUOUS MONITORING:


Variations in the components of the geomagnetic field; The intensity of natural electromagnetic radiation; Variations of the electrotelluric field; Atmospheric pressure, humidity and air temperature; Seismic and geodynamic observations; Hydrodynamic regime of groundwater. A comprehensive analysis of the results of continuous observations and, based on them, the determination of the mechanism of manifestation of the precursors of the prepared earthquakes.


THE MAIN TASKS OF THE LABORATORY:



- Continuous observations of variations (components of the geomagnetic field, electromagnetic pulses)in order to determine the mechanism of manifestation of the precursors of the prepared earthquakes
- Registration and analysis of geodynamic processes in order to assess the current movements of the Earth's crust;
- Conducting continuous seismic observations;
- Explore the age-old variations of the earth's magnetic field;
- Testing and evaluation of the effectiveness of newly acquired geophysical instruments.
- Performing the function of a reference station for geophysical observations conducted at the Republican Center for Seismic Monitoring of the Ministry of Emergency Situations.


MAIN SCIENTIFIC RESULTS ACHIEVED IN RECENT YEARS:


Secular variations in the Earth's magnetic field, variations in electromagnetic and electrotelluric fields, as well as changes in radon concentration in soil and groundwater levels were studied. Anomalous changes were recorded in their variations, which are harbingers of earthquakes, and the mechanism of their manifestation was determined. Anomalous variations in the average values of the amplitudes and the number of electromagnetic pulses were detected, preceding the Tuyabuguz and Marzhanbulak earthquakes of 2013, as well as two earthquakes that occurred in 2019. A comparison of data from the observatory and 14 stationary magnetometric stations operating in the republic made it possible to record bay-shaped anomalous variations of the geomagnetic field of various signs with an amplitude of 3-5 NT at several stations.
Variations of electromagnetic pulses with a frequency of 2 and 12 kHz before the Tuyabugyz and Marjonbulok earthquakes on May 24 and 26, 2013. Microseismic observations conducted at the Tashkent Geodynamic Range were analyzed using the Geopsy and JSesame programs. It was found that anomalies in the Earth's magnetic field, electromagnetic pulses, and changes in groundwater are interrelated. Based on a comprehensive geological and geophysical analysis, the geodynamic activity of the territory of the Tashkent geodynamic polygon was assessed.
