8. Ask the students to recall how scientists use seismic wave observations to investigate the interior structure of the Earth. This is similar to checking the ripeness of a melon by tapping on it.

To give you an idea how these numbers can add up, think of it in terms of the energy released by explosives: a magnitude 1 seismic wave releases as much energy as blowing up 6 ounces of TNT. A ...

A new wave of seismic science is emerging from the ocean floor—and it could help us predict the next big disaster. Using a ...

More recently, researchers have been using satellite measurements to detect small ... measure and monitor the seismic velocity changes continuously," Mao said. Seismic wave speed varies with ...

which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy" on dry, wet, and frozen diabase samples. Experimentation revealed that the seismic velocities of the dry ...

This also caused a seiche — a standing wave that oscillated in the fjord for nine days, generating the prolonged seismic signal. Scientists linked the landslide to the thinning of the glacier in ...

On March 30, a powerful 7.3-magnitude earthquake struck near the island nation of Tonga in the South Pacific, prompting the Pacific Tsunami Warning Center to issue a tsunami warning for the region.
