In many publications, as well as in media statements, prominent foreign and Bulgarian seismologists admit that seismology still does not have reliable methods and technical means for the identification of earthquake precursors in marine conditions (short-term forecast). Several facts, circumstances, and considerations are presented, motivating the need to immediately start experimental research in this area. A Bulgarian patent of a device for capturing underwater gas sources is offered for transmitting characteristics of the underwater gas source to a receiving device on land, indicating an impending earthquake. A strategy for experimentation and application of the device through the implementation of a new European project, uniting the forces and capabilities of the South European countries, is being proposed.

The modern conditions, the received results and possible prospects of short-term forecasting of strong earthquakes are analysed. On examples of concrete researches it is shown, that such forecast with a required detail, accuracy and reliability is not carried, and is not expected in the future. It is fundamental consequence of nonlinearity of the seismic geodynamic systems functioning deterministically-chaotically in the fractal geologic medium. Effectiveness of forecasting in the form of attitude of number of successfully predicted earthquakes to number of registered ones on some certain area is not above several percent. Frequent messages about ostensibly reached almost 100%-s’ of effective short-term forecasting are denied by absence of adequate reliable methods, and by steady extension of the list of the not predicted seismic catastrophes.

We have applied chemistry-climate model (CCM) SOCOL to simulate the distribution of the temperature and gas species in the upper stratosphere and mesosphere. As an input for the simulation, we employ daily spectral solar UV irradiance measured by SUSIM instrument onboard UARS satellite in January 1992. We have carried out an ensemble of nine 1-month long simulations using slightly different initial states of the atmosphere. We have compared the obtained time evolution of the simulated species and temperature with available satellite measurements. The obtained results allowed us to define the areas where the nowcast and short-term forecast of the atmospheric species with CCM SOCOL could be successful.

The article deals with the problem of the emergence and functioning of financial pyramids based on the use of digital assets, using the example of the «Finico» project. The main performance indicators are analyzed, as well as the reasons that influenced the success of this project, its scale and duration of existence are characterized. Particular attention is paid to the ways of organizing and carrying out illegal financial activities with signs of financial pyramids, and some measures are proposed to counter it. A short-term forecast of an increase in the number of crimes committed using information, telecommunications and digital technologies in this area is given.
