The primary activities of the integrated mobile laboratory (EQ-MOBI-LAB) for field research and damage assessment from earthquakes and other events include:
- Urgent, near real-time non-destructive testing (NDT): monitoring, diagnosing, assessing conditions, and defining emergency protection measures for structures, infrastructure, critical systems, soil constructions, and other systems exposed to:
- Natural disasters: earthquakes, landslides, terrain collapses, floods, and others;
- Technical accidents and disasters: explosions, fires, consequences of poor construction quality or inadequate operational regimes, material fatigue, aging structures, infrastructure, and others;
- Warfare: as a result of airstrikes, artillery attacks, unexploded ordnance explosions, and others;
- Threats: terrorism, sabotage, and more;
- Regular monitoring and diagnostics of structures, critical, and other infrastructure systems for their maintenance, upgrading/expansion, reactivation, capacity enhancement, and more;
- Quality and defectology of construction materials;
- Environmental protection;
- Qualitative and quantitative analysis of phenomena related to the static and dynamic behavior of soil masses, deposits, structures (embankments, cuttings, excavations, fill dams, etc.), and their transformation into hazards for populations and created assets;
- Transfer and development of methodologies, techniques, technologies, and procedures for NDT monitoring, diagnostics of structures, vital infrastructure, and critical systems; qualitative and quantitative analysis, and defectology of soil structures and natural systems.
