What are the relations between seismometer and geophone?

What are the relations between seismometer and geophone?   Microtremor is a kind of weak vibration generated by nature or human activities, with an amplitude of only a few microns to dozens of microns, which can be observed on seismometers.   What is Microtremor Survey?   Microtremor survey is a detection method that collects micromotion […]

What is a MASW?

What is a MASW?

What is a MASW?   MASW is a shortcut of Multichannel Analysis of Surface Waves. The MASW method deals with surface waves in the lower frequencies(e.g.,1-30Hz) and uses a much shallower depth range of investigation ranges from a few meters to a few tens of meters. MASW deals with relatively lower frequencies and shallower investigation […]

How to use seismic methods?

How to use seismic methods?   When you have a need for non-destructive investigation technique for subsurface conditions, seismic methods can be a good alternative to provide a more comprehensive image compared to traditional intrusive methods such as digging and drilling. Seismic methods record the movement of vibrations through the round with their speed and […]

How to select a suitable geophone for certain seismic method?

How to select a suitable geophone for certain seismic method?

Geophones are used in seismic investigations to transform the vibration in the ground into a voltage. The geophones are analogue sensors, with a spring-mounted wire coil moving past a magnet. This creates the electrical signal with is recorded by a seismograph such as the ABEM Terraloc, PASI GEA 24, Geode 24 or DAQ Link 3 […]

What is VES, ERT, IP and SP Electrical Resistivity ?

What is VES, ERT, IP and SP Electrical Resistivity ?

  What is electrical resistivity?   Electrical resistivity sends an electrical current into the ground and maps the resistance against that flow of the current. The resistance can be converted to resistivity, a property used to predict the composition, structure or strength of the underlying materials. As we all know, different geological materials present different […]
