Research Areas

Decreasing of consequences of strong earthquakes is a complicated scientific and technical problem which is of great social and economic significance.  Its topicality grows continuously due to the growth of technogeneous load on ecosystem.

Presently, scientific researches aimed at solution of this problem are mainly developing in two directions: a) development of methods of strong earthquakes prediction; b) detailed seismic zoning and designing of buildings and constructions with due account for the predicted seismic magnitude.  Development of methods of accurate forecast is far apart from its finish. The second direction is too costly. For example, raising of seismic resistance by one number increases its cost approximately two times.

LESMS activities are aimed at development of physical basis of the third direction – decreasing of seismic risks by means of artificial discharge of tectonic stresses. At the end of the 20th century, anthropogenic activities of mankind which have reached the planetary scale became the reason of induced (artificially made) seismicity. Such seismicity occurs, for example, during underground nuclear explosions, injection of liquid industrial waste to wells located in seismic areas, during filling of large water reservoirs and development of minerals. In 1976-1983, the Institute of Earth’s Physics and the Institute of High Energy Densities received the unique results on the influence of electromagnetic pulses produced by magnetohydrodynamic (MHD) generators on the seismic regime near Harm and Bishkek geophysical test sites.

The received data show the possibility for development of methods of reducing seismic risks. These methods consist in external controlled influence on the natural seismic process with the purpose of changing its mode and initiating the release of elastic energy accumulated in medium in the form of relatively weak earthquakes with the purpose of preventing a disastrous seismic event.  

Presently, the LESMS works in two directions of studying the external energy impacts on geological medium:

- laboratoriy simulation using samples of geomaterials (centimeter sizes of samples – scale of microcrack formation),

- measurements of geoacoustic emission in wells (scale level of micro- and “nanoearthquakes” with the source size from several meters to several tens of meters (magnitudes M<0)).

2007 – creation of the lever press on the base of UDI.

2008 – joint works with V.A.Gavrilov (Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences) which initiated the development of a new direction of researches – detection of geophysical medium response to external actions by measuring geoacoustic emission in wells using geoacoustic sensor (geophone).

2008-2009 – development of complex for measuring geoacoustic emission and conduction of the first field measurements.

Presently, we continue our studies in both directions.
