sonic test
? Ultrasonic testing, also called ultrasonic inspection, is a method of testing materials that uses sound waves generated by an ultrasonic probe to evaluate a materials characteristics. Ultrasonic testing is most commonly used to detect flaws or irregularities in steel and other metal parts, as we......
Earthquake Observation
Ground Motion Microseismic Observation Microseismic monitoring is a technology that detects and records microseismic activities of the Earth’s subsurface. The technique provides direct insight into the mechanical behavior of a rock mass, thus enabling detailed characterization of the subsurface.......
deformation observation
Spacetime is an essential concept for understanding fundamental physics, and research into its properties has been ongoing for many years. The idea of a four-dimensional space-time continuum was first proposed by Albert Einstein in his Special Theory of Relativity around 1905. Although this concep......
Earthquake Area Survey
Earthquake Zone Survey Earthquakes are a major natural disaster that can occur anywhere in the world. When such an event happens, it is important to survey the affected area to ensure that it is safe for people to inhabit. This includes assessing the physical damage that has been caused, both to ......

tunnel survey
Tunnel Exploration Tunnel exploration is a critical aspect of the engineering process. A tunnel can provide valuable insight into geological and structural characteristics, enabling engineers to make informed decisions regarding construction and rehabilitation technologies. Tunnel exploration ca......
Engineering Seismic Exploration
Engineering Seismic Exploration Engineering seismic exploration is a technique used when looking for petroleum, gas and other materials below the surface of the earth. In this process, shock waves are sent into the ground and seismic reflections, or echoes, are detected and studied. This can help......
ground radar method
Geophysical Radar Geophysical radar methods are used to explore and monitor the subsurface of the earth in order to locate reserves of oil, gas, minerals, and other valuable resources. Geophysical radars use electromagnetic waves from portable or fixed sources to detect changes in the electrical c......
Engineering electrical prospecting
Engineering geophysics is a branch of geophysics which applies its methods to engineering problems. Examples of engineering geophysics applications are locating buried services, sub-surface voids, mineral exploration, groundwater exploitation, and archaeological survey. These applications use phys......
Engineering Geophysical Exploration Instruments
Geophysical Exploration Instruments Geophysical exploration instruments are an important tool for geologists and engineers to understand the processes and materials that make up the Earths crust. These instruments measure various features of the Earth, including seismic activity, resistivity, and......
