18.12 FORCED-DAMPED VIBRATIONS
... The plot of magnification factor against the ratio of frequencies (w /wn) for different values of z is shown in Fig. 18.22(a). The curves show that as the damping increases or z increases, the maximum value of the magnification factor decreases and vice-versa. When there is no damping (z = 0), it re ...

Types of seismic waveS
... Secondary waves (S-waves) are shear waves that are transverse in nature. These waves arrive at seismograph stations after the faster moving P waves during an earthquake and displace the ground perpendicular to the direction of propagation. Depending on the propagational direction, the wave can take ...

Seismic communication
Seismic communication, sometimes called vibrational communication, describes the conveying of information through seismic vibrations of the substrate. The substrate may be the earth, a plant stem or leaf, the surface of a body of water, a spider’s web, a honeycomb, or any of the myriad types of soil substrates. Seismic cues are generally conveyed by Rayleigh waves generated through vibrations on the substrate, or acoustical waves that couple with the substrate. Vibrational communication is an ancient sensory modality and it is widespread in the animal kingdom where it has evolved several times independently. It has been reported in mammals, birds, reptiles, amphibians, insects, arachnids, crustaceans and nematode worms. Vibrations and other communication channels are not necessarily mutually exclusive, but can be used in multi-modal communication.
