There is observational evidence that the global sea levels are rising and increasing the risk to coastal communities from floods and erosion. Interest in marine sea level research is determine not only by forecasting cataclysms and sea level rising, but also in connection with interdisciplinary studies exploring the causes of this change. The article outlines time series analysis of tide gauge data to solve for short and long-term sea level variations at Varna and Burgas tide gauge stations. The data covered the p...

The study of recent crustal movements is one of the priority areas of the Earth sciences. Geodetic methods occupy a particularly important place in the general complex of measurements and investigations of crustal movements because they provide quantitative information on the condition and development of geodynamic processes. The paper outlines the newly accepted project with main goal monitoring the geodynamic processes in the area of Sofia. This goal will achieve by periodic GNSS measurements over the Sofia geod...

The study of landslides is of particular importance because they can lead to great material damage. The region of the Bulgarian northern Black Sea coast is affected by many landslides and it is important to monitor motions of the major landslides in this area. The paper outline deformation analysis of the landslide processes in the area of ?Dalgiya yar?. It is a landslide circus from the Varna landslide region that covers several active landslides, whose boundaries are overlapping and for that reason are difficult...
