Urban areas developed above salt-karst systems are particularly sensitive to ground deformation processes driven by dissolution, suffosion, and anthropogenic disturbances. Detecting and monitoring these processes in densely built environments requires observation techniques capable of capturing small-scale morphological changes with high spatial resolution and repeatability. This study demonstrates the use of recurrent UAV-based LiDAR surveys to detect and measure ground instability in the town of Slanic Prahova (...

Urban areas built above salt deposits are especially vulnerable to ground instability caused by dissolution, suffosion, and human activities. Monitoring these environments is difficult due to the complex subsurface structures and dense infrastructure constraints. Understanding the dynamics of these processes requires combining multiple investigation and monitoring methods to capture both underground conditions and surface movements. This paper shares initial findings from an ongoing multi-method monitoring project...

Understanding environmental change relies on observational technologies that analyze the interaction between electromagnetic radiation and matter. Spectroscopy provides the physical foundation for many sensing techniques used in Earth sciences, operating across the ultraviolet (UV), visible (VIS), and infrared (IR) spectral domains. Technologies such as LiDAR, thermal imaging, photogrammetry, and optical remote sensing rely on these principles to observe environmental processes and monitor changes in the Earth sys...

The global development of society requires constant updating of the objectives that education pursues and how they are achieved. Science education is an area undergoing advanced transformation, both at the level of objectives and methodologies, with a strong social, economic, and knowledge impact. Research-based education is a well-established term, especially in the higher education system. More studies and key policy documents argue that education must be based on cutting-edge research. Essential in this equatio...

Over the last few years, science has advanced unprecedentedly in explaining phenomena and facts with a high impact on society: earthquakes for example. On the other hand, new technologies are transforming the way (seismological) information is collected and transmitted to public and other various stakeholders categories. From interactive multimedia content to immersive experiences, difficult concepts become easier to be transmitted and understood by a wide variety of audience, starting with children, a most import...

In this paper, we analyze almost ten years of continuous recordings (November 2007пїЅ April 2017) from 114 stations of the Romanian Seismic Network using the power spectral densities and their corresponding probability density functions (PSD PDF). For each vertical station component, we compute the statistical mode for noise levels from the PSD PDFs. The noise mode represents the highest probability noise level for a given station. We then construct the PSD PDF mode low-noise model for Romania (RONM) from the mini...

A decade of improvements and new development of tools for observation statistics, standard point positioning, clock-jumps and cycle-slip detection and other interruptions over all constellations, frequencies and signals, satellite elevations and azimuths, elevation-specific histograms, satellite ascending/descending times for horizon and user elevation cut-off, pseudo-range multipath and noise, carrier-phase signal-to-noise ratio, data gaps and small data pieces and other useful lists and statistics allow us to an...
