The U.S. Geologic Survey (USGS) insists that earthquake forecasting is not possible. Thus, the agency only calculates the ...

P-waves (P stands for primary ... and ask your students to point out different seismic waves. In addition, shear waves cause much more damage to structures since it is easier to shake surface ...

Seismic waves are the best tool scientists have to peer inside a planet, especially since we can’t drill into the Martian mantle or core. When a quake or impact occurs, it generates P-waves ...

Explore how North America is changing as its deep cratonic root thins and pieces are dripping into the Earth's mantle.

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep inside the Red Planet.

The P wave will be the first wiggle that is bigger than the background signals). Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The ...

It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and cause the most damage. A P wave is a longitudinal wave and travels the ...

Scientists have long known that there are LLVPs — one below the Pacific Ocean and the other below Africa. In these regions, seismic waves from earthquakes travel 1% to 3% more slowly than they ...

In the lab, Katayama and Akamatsu measured P-wave and S-wave velocity using a piezoelectric transducer, which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy ...

A massive 7.7 earthquake originating in Myanmar has collapsed buildings over 600 miles away in Bangkok, Thailand ...

The study of seismic waves provides evidence for the internal structure of the Earth, which cannot be observed directly. P waves are detected on the opposite side of the Earth. Refractions between ...
