Definition from
Wikipedia:
Vibroseis is a method used to propagate energy signals into the earth over an extended period of time as opposed to the near instantaneous energy provided by impulsive sources. The data recorded in this way must be correlated to convert the extended source signal into an impulse. The source signal using this method was originally generated by a servo-controlled hydraulic vibrator or shaker unit mounted on a mobile base unit, but electro-mechanical versions have also been developed.
Example sentences:
Vibroseis is a method that imparts coded seismic energy into the ground. The energy is recorded with geophones and then processed using the known (coded) input signal. The resulting time-domain representation of vibroseis data is an impulsive wavetrain with wavelet properties consistent with the coded input signal convolved with the earth's reflectivity series. (Ingenta Connect)
As the demand for high-density and wide-azimuth data increases, HPVA enables high-performance vibroseis crews to increase survey specifications whilst maintaining high production rates and data quality. (CGG Veritas)
Computer processing of the seismic signals from a vibroseis source uses the distinct characteristics of the sweep to "collapse" the energy into short duration wavelets—essentially equivalent to the seismograms that would be recorded with impulsive sources such as explosives. (Carleton College)

b) în cazul acceleraţiei orizontale maximale în sens longitudinal: după caracteristicile peretelui (dimensiuni, proporţii, metode de construcţie, rezistenţa materialelor şi adesea mortarul de legătură etc.), acesta fie vibrează în ansamblu, ca un întreg (Fig.5), fie fracţionat în mai multe bucăţi care vor răspunde fiecare în mod diferit şi independent la vibraţia seismică indusă prin sol (Fig.6).
