The seismic wave kept going for four years, but the worst was over after about six months.

Seismic waves travel at a particular speed in the Earth.

It would, they said, create a seismic wave of similar programs across the country, shifting students, money and attention from public to private schools.

However, if the seismic waves were reflected back at him, he would be injured.

There are three sorts of seismic wave sources on the Moon.

First measurements are made of seismic waves passing through a material.

Seismic waves move more quickly through rock than through air.

And the tiny earthquakes usually began soon after a particularly large seismic wave passed through the region.

In the rocks themselves, these vibrations are called seismic waves.

For an instant he thought that another seismic wave was passing beneath them.

It is seismic waves that we feel as shaking during an earthquake.

When an earthquake occurs, seismic waves travel throughout the earth.

It is these seismic waves that cause the ground to shake near an earthquake.

Do you like to better understand what happens when seismic waves get through the ground-structure system?

We'll explode it, and the explosion will generate seismic waves.

Seismic waves are indicators of energy disbursement within the earth.

In the process energy is released in various forms, including seismic waves.

Natural or artificially created seismic waves can be used to map structures in the Earth.

Seismic waves are vibrations that travel through the Earth's interior or along its surface.

Both types of events release seismic waves that accelerate the ground at and below the surface.

The seismic waves that followed the eruption in Krakatoa killed 37,000 people.

For example, seismic waves that travel through the earth are sometimes used to help identify geothermal sources.

The seismic waves turn the ground to quicksand, sucking whole streets into the earth.

In geology, it is important in the study of seismic waves.

Powerful seismic waves started to pulse through the supercompressed matter at the star's core.
