MASW and Mapping of Shear Wave Velocity

What is MASW?

MASW stands for Multichannel Analysis of Seismic Waves, and is a way to measure the Shear Wave velocity (Vs), which is an elastic constant of Young’s modulus. This helps to determine the ground strength, or stiffness, and load-bearing capacity.

MASW is also used to map out soil strength without the need for drilling. This helps to identify rock head depth, soil stiffness, and void location.

A very powerful and fast geophysical method.

Utilize a geophysical survey and advanced processing techniques to precisely measure the Shear wave velocity of the soils.

Active mode – to 25m

Passive Mode up 100m range .     No need for sources uses natural ground noise source
