DETECTING URBAN GROUND INSTABILITY USING RECURRENT UAV LIDAR SURVEYS: CAPABILITIES AND LIMITATIONS FROM A SALT-KARST MONITORING SITE IN ROMANIA

(STEF92 Technology, 2026, Eduard Nastase, Alexandru Tiganescu, Dragos Tataru)

Show more

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 (...

EARLY OBSERVATIONS FROM MULTI-METHOD MONITORING OF GROUND INSTABILITY IN A SALT-KARST URBAN AREA

(STEF92 Technology, 2026, Dragos Tataru, Eduard Nastase, Bogdan Grecu, Alexandru Tiganescu, Alexandra Gerea)

Show more

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...

FACILITATING GEOSCIENCE EDUCATION THROUGH INTEGRATED EARTH SCIENCE THEMATIC SERVICES PLATFORM

(STEF92 Technology, 2022-11-15, Dragoş Tătaru, Eduard Nastase, Dragoş Toma-Danilă, Bogdan Grecu, Alexandru Țigănescu)

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...

PRELIMINARY ANALYSIS OF DATA RECORDED ON INSTRUMENTED BUILDINGS FROM BUCHAREST AREA DURING THE 28TH OCTOBER 2018 VRANCEA EARTHQUAKE

(STEF92 Technology, 2019-06-20, Alexandru Țigănescu)

Show more

The purpose of this research is to analyze the data recorded on instrumented structures in Bucharest and adjacent free-field seismic stations during the last moderate earthquake that occurred on 28th of October 2018 in the Vrancea seismic zone. The earthquake had a 5.5 moment-magnitude, a depth of 147.8 km, and it was felt on a large area of Romania, generating very little damage in Bucharest. In the last five years, the National Institute for Earth Physics has deployed permanent instrumentation (accelerometers) a...
