Detection of fire accelerants is the process that a fire investigator uses to determine if fire accelerants were used at a fire scene. This process involves a combination of both field work and laboratory analysis by fire investigators and chemists. In order for a positive identification of a fire accelerant to occur both field work and ...
A soil sample recovered from a test boring using a split spoon sampler. Borings come in two main varieties: large diameter and small diameter. Large-diameter borings are rarely used because of safety concerns and expense but are sometimes used to allow a geologist or an engineer to visually and manually examine the soil and rock stratigraphy in-situ.
Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.
Fire scene reconstruction is critical to understanding complicated fires. When normal approaches fail, laboratory reconstructions become critical. They contribute to the resolution of critical issues and the enhancement of fire safety. A reconstruction's objective, whether it is a test, experiment, or demonstration, must be clearly stated.
Job responsibilities of an engineering geologist include: collecting samples and surveys, conducting lab tests on samples, assessing in situ soil or rock conditions at many scales, preparing reports based on testing and on-site observations for clients, and; creating geological models, maps, and sections.

Data filtering enables the extraction of bare-Earth's surface by removing unnecessary data or data noise. [26] For rock orientation studies, outcrop mapping and topographical studies, they only acquire information about the rock slope bodies. Thus, data filtering is implemented to separate the point clouds as ground and non-ground features.
Subsurface exploration usually involves in-situ testing (for example, the standard penetration test and cone penetration test). The digging of test pits and trenching (particularly for locating faults and slide planes) may also be used to learn about soil conditions at depth. Large-diameter borings are rarely used due to safety concerns and ...
The principal objective of the engineering geologist is the protection of life and property against damage caused by various geological conditions. [4] The practice of engineering geology is also very closely related to the practice of geological engineering and geotechnical engineering. If there is a difference in the content of the ...
