Geotechnical investigation - Wikipedia

Geophysical methods are used in geotechnical investigations to evaluate a site's behavior in a seismic event. By measuring a soil's shear wave velocity, the dynamic response of that soil can be estimated. There are a number of methods used to determine a site's shear wave velocity: Crosshole method; Downhole method (with a seismic CPT or a substitute device)

Borehole - Wikipedia

The British sinologist and historian Michael Loewe states that borehole sites could reach as deep as 600 m (2000 ft). K.S. Tom describes the drilling process: "The Chinese method of deep drilling was accomplished by a team of men jumping on and off a beam to impact the drilling bit while the boring tool was rotated by buffalo and oxen."
