Examples

  • In addition to the compressional and shear waves that propagate through the body of the Earth, there are two modes of transverse surface waves that propagate only along the Earth's crust:

  • Negative strain is compressional; positive tilt is down to the east and north.

  • And they do just as well with the propagating compressional and shear waves that are the principal dynamic consequences of earthquakes.

    Academic text (1993)
  • One knows about the liquid core of the planet, for example, because compressional waves can propagate in liquids but shear waves can't.

  • I say the lack of very large earthquakes at such a compressional junction point shows that this region is just as dangerous, or more so, than the fault rupture in Indonesia that was 9.1.

  • The surface area of a bubble is larger during the dilatational phase of the pressure wave, when the volatiles exsolve from the fluid into the bubble, than during the compressional phase, when the volatiles dissolve back into the fluid.

  • A thousand kilometers from the fault zone, the ground in Sri Lanka vibrated with amplitudes greater than 9 cm within a minute after the first compressional waves arrived, and longer-period surface-wave motion eventually exceeded 1 cm everywhere on Earth's surface.

  • During an earthquake, the most damaging effects are often caused by compressional waves that shake the ground intensely.

  • The scientists studied how compressional forces affected the stability of the building's foundation during stress tests.

  • As the rock layers were pushed together, they experienced significant compressional stress, altering their structure.

compressional positive

Morphology

compressional = compression (transparent) = compress + ion + al

The adjective is built in a regular and easily interpretable way from the noun compression plus the suffix -al.

Etymology

Compressional comes from com- meaning 'together' and press meaning 'to push', the same idea you see in press and pressure. So something described as compressional is caused by being pushed or squeezed together, like waves or forces that press parts of a material.
