MAIN SCIENTIFIC RESULTS ACHIEVED IN RECENT YEARS

- A regional database of synthetic accelerograms was created for 12 regions and the Republic of Karakalpakstan, covering seismogenic zones in Uzbekistan and adjacent territories. Probabilities of exceedance at 90%, 95%, 98%, and 99% for various soil conditions were calculated for use by design organizations.


- A methodology for early warning and emergency reporting on strong earthquakes in Uzbekistan was developed, along with the “Strong Earthquake Warning” mobile application. The national early warning system for strong earthquakes was launched in test mode. An accelerometer for transmitting maximum P-wave acceleration values via network was developed. A “Seismic Impact Intensity Indicator” device based on the Arduino Uno microcontroller was produced.


To improve continuous instrumental seismological monitoring in seismically active areas, technogenic and microseismic measurements were conducted at the Tupolang, Hisorak, Pachkamar, Rezaksoy, Karkidon, Andijan, and Chorvoq reservoirs. Based on local engineering-geological and geomorphological data, vibration amplitudes caused by environmental factors, their resonance periods, and amplification coefficients were determined.
