Geophysical survey

Geophysical studies are scientific methods that measure physical properties of rock formations. Common properties investigated include magnetism, specific gravity, electrical conductivity and radioactivity. Surface as well as borehole geophysical surveys can be executed.

Surface seismic survey might include seismic refraction, seismic reflection, Multi-channel Analysis of Surface Waves (MASW) and Spectral Analysis of Surface Waves (SASW). Borehole seismic survey comprises full wave sonic logging, cross-hole seismic test, cross-hole seismic tomography.

Conduct field exploration by geophysical soundings using seismic and electrical methods, as part of the project: "Geophysical Research Palo Redondo dam - Stage III Chavimochic Special Project ".

The geophysical evaluation was performed by ground exploration using seismic refraction testing and electrical tomography testing, whereby the power of the layers was determined following the interpretation of P wave (Vp) velocities and the resistivity values respectively.

Further tests following Multichannel Analysis of Surface Waves (MASW) methods and Microtremor Array Measurement (MAM) were performed to obtain a velocity profile of S waves (Vs), the same that allow to properly calibrate seismic refraction lines executed. These tests allow to analyze dynamic and electrical subsurface properties getting seismic profiles as well as electrical bidemiensional profiles.

Seismic geophysical exploration was carried out in order to determine the propagation velocity of Vp and the propagation velocity of the Vs of the study area, by testing surface seismic refraction by measuring Vp and MAM and MASW tests for profiles Vs waves, values ​​that will let determine the thicknesses of the layers in the area and the dynamic soil parameters.
