This paper highlights the results of the assessment of operational risks related to the components of the dangerous goods transport chain. Due to the fact that multiple parties are involved in handling and transport procedures, numerous different risks may arise during activities involving dangerous goods. By identifying and assessing risks, the most critical ones are identified and evaluated according to the potential damage they may cause to the entire transport chain. The results of the risk assessment in the t...

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...

The road transport of dangerous goods may have severe consequences in the event of an accident. The consequences of a road accident involving a heavy vehicle transporting dangerous goods can affect not only the truck driver but also the nearby population. Route selection is a complex issue, influenced by multiple parameters that may vary over the course of a day, a week, or a month. The ultimate objective is to enhance safety through the complete digitalization of the risk management process for the transport of d...

The seismicity of Albania is primarily driven by the collision between the Adria microplate and the Albanian orogen. The Ionian fault zone, located in southwestern Albania, is characterized by NW-SE trending neotectonic thrust faults with oblique components. These faults are predominantly marked by NW extension and include pre-Pliocene overthrust faults subjected to pure compressive stress. Occasionally, these overthrust faults are intersected by NE-SW-oriented thrust faults. The Ionian overthrust fault zone exten...

MAGNETIC STUDIES AROUND THE BITLIS ZAGROS SUTURE ZONE (TURKEY)

(SGEM Scientific GeoConference, 2010, O. Pamukcu, Z. Akcig)

Show more

The tectonics of the Turkey is dominated by the collision between the Arabian and Eurasian plates. In this collision, the Bitlis Zagros Suture Zone is the most prominent tectonic structure. There exist metamorphics of the accretionary prism. Tectonic forces of the study area can be effective on thermal structure and mantle flow. Particularly in such areas, the magnetic anomaly is imposed by the thermal zone. For this purpose in this study, by investigating aeromagnetic anomaly of the Bitlis Zagros Suture Zone, we ...

MAGNETISM OF STREET DUST FROM SOFIA CITY – QUANTITATIVE INDICATION ABOUT DEGREE OF ENVIRONMENTAL POLLUTION

(SGEM Scientific GeoConference, 2010, D. Jordanova, D. Todorova, TS. Tsacheva)

Show more

Qualitative picture of the degree of environmental pollution in Sofia city was obtained using magnetic signature of road dust. Collection of 117 samples was studied by magnetic methods and SEM microscopy. The most polluted points are central part of the city and main crossroads. Both irregular-shaped and spherical particles of high-iron content are responsible for the enhanced magnetic signal in the road dust.

NUMERICAL DEFORMATION MODELLING USING GNSS DATA ON EXTENSIONAL ZONE

(SGEM Scientific GeoConference, 2010, A. Yurdakul, O. Pamukcu, Z. Akcig)

Show more

Numerical models which are used for determining deformation are created as a simplified form of physical reality and they are usually defined as force or timedependent. The deformation is investigated by static, kinematic and dynamic models. From these models, dynamic deformation model describes the relationship between the forces and the changes of forces depending on time and the external factors which cause deformation. The deformation in an area is determined by evaluating together the theoretical dynamic mode...

SEABED FEATURES FROM A SIDE SCAN SONAR SURVEY AT NORTH OF ANTIMILOS ISLAND

(SGEM Scientific GeoConference, 2010, A. Mitrousis)

Show more

The side scan sonar is the main tool for deep marine archaeology research but is also equaled significant in mapping of underwater geophysical features. Ancient and modern shipwrecks can be located with the correct translation of sonar records in conjunction with visual inspection. During a short but difficult side scan sonar survey (for documentary film purposes) in searching for the shipwreck HERAKLION (without results), at the sea area north of Antimilos island (South Aegean Sea, Greece), we recorded two intere...

THERMAL PROPERTIES OF THE URALS SERPENTINOUS DUNITES (OLIVINE ROCK) AT ELEVATED TEMPERATURES

(SGEM Scientific GeoConference, 2010, A. Lipaev, S. Lipaev, L. Alekseeva)

Show more

The authors were the first to carry out the investigation of thermal properties of serpentinous dunites (olivine rock) at Mount Soloviev, Nizhny Tagil duniteclinopyroxenite massif. The collection studied includes 12 dunite samples varying in the degree of serpentinization in the range of values from near 0 to practically 100\%. The samples of serpentinous dunites from the Urals were investigated for thermoconductivity and thermal diffusivity by the apparatus applying the method of periodic heating in the system of...

A NEW DESIGN FOR GEOELECTRIC SURVEYING AND INVERSE 1D AND 2D MODELING: THE CASE OF KARONGAH LEAD-ZINC MINE, KERMAN, IRAN

(SGEM Scientific GeoConference, 2009, H. Sarkheil, H. Hassani)

Show more

Since the resistivity and induced polarization methods have an important role for exploration of concealed lead and zinc, in order to assess the Lead and Zinc layers in an ancient mine, Karongah of Kohbanan, four geoelectrics profiles designed and surveyed in shlumberger array, so that these directions were almost vertical in compare with layers direction and they were include 14, 10, 8 and 9 sounding stations respectively. After geological assessment and one dimensional and two dimensional inverse modeling, we dr...

ACOUSTIC WAVE PROPAGATION IN STROGLY HETEROGENEOUS MEDIA: A LATTICE BOLTZMANN APPROACH

(SGEM Scientific GeoConference, 2009, S. A. Abolghasemifar, M. S. Monfared, H. Aghajani)

Show more

Here we show how a lattice Boltzmann based approach accurately model acoustic wave propagation in strongly heterogeneous media. Rather than solving a partial-differential wave equation in a continuous medium, the lattice-Boltzmann based method directly simulates the physical processes of wave propagation: transportation, reflection and transmission. It can accurately handle sharp interfaces at any locations along lattice links, and total reflections from free surfaces or empty bubbles. I used empty and nonempty bu...

ADVANCES IN ELECTROMAGNETIC SOUNDING OF GEOTHERMAL AREAS

(SGEM Scientific GeoConference, 2009, V. Spichak)

Show more

The paper presents a brief review of the results obtained recently in Geoelectromagnetic Research Centre IPE RAS on electromagnetic sounding of the geothermal areas. The case studies are shown illustrating application of the developed methods to 3-D imaging geothermal area, mapping the geothermal reservoir and monitoring the faults’ macroparameters. A special attention is paid to the temperature estimations using recently developed indirect electromagnetic geothermometer.

COMPARISON BETWEEN FREQUENCY-DOMAIN HELICOPTER ELECTROMAGNETIC DATA INVERSION RESULTS BASED ON NUMERICAL SOLUTION OF FAST HANKEL COEFFICIENTS AND LAPLACE’S METHODS

(SGEM Scientific GeoConference, 2009, D. Rajabi, A. A. Amiri, A. Kamkar-Rouhani, A. Moradzadeh)

Show more

Nowadays, airborne electromagnetic methods are widely used to investigate subsurface areas. One of these methods is helicopter electromagnetic method. The basis of inverse modeling of frequency-domain HEM data is to solve Mundry’s integral numerically. Various methods have been invented for numerical solution of this integral, such as Laplace transform, fast Hankel coefficients and Jacobian methods. To analyze helicopter electromagnetic data, we need inverse programs which can assist us to achieve the best or ac...

Electromagnetic (EM) methods are among geophysical methods which have many various applications. Besides, EM surveys are carried out rapidly with low costs. Thus, they are being fast developed. The methods, compared to other geophysical methods, have the most various acquisition systems. EM surveys can be carried out in the land, air, sea and borehole. During 1950s in Canada, airborne EM methods, in which helicopter EM (HEM) method is also included, have assisted in mineral exploration valued more than 10 milliard...
