Seismic waves are the waves that travel through the Earth and are generated from an earthquake, volcanic eruption or an explosion (which may be due to humans). These waves are low-frequency waves and are of two types, surface waves and body waves....

can time the P and S wave propagation in the human wave using a stopwatch.Because the shear wave motion is more complicated in the human wave,the S wave will have a slower velocity(greater travel time from source to the end of the line of people), similar to seismic waves in a solid...
Many engineers and architects now believe it's possible to build anearthquake-proof building-- one that would ride the waves of the most fearsome temblor and remain as good as new once the shaking had stopped. The cost of such a building, however, would be staggering. Instead, construction ...
But every so often, a big earthquake occurs, and when that happens, the pulses of energy it releases, called seismic waves, can wreak almost unfathomable destruction and kill and injure many thousands of people [source: Bolt]. That sort of cataclysm occurred on March 11, 2011, in Japan, ...
A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed
How do active and passive transducers work (in electronics)? What is the difference between pitch and loudness in sound waves? What is the importance of water in maintaining health? Calculate the current passing through a resistor in parallel when the total voltage...
A Damper is any material or device that absorbs vibrations. Seismic dampers dissipate the energy of seismic waves moving through a building structure. ... Dampers workby converting the kinetic energy of bouncing or swaying into heat energy, which then (typically) dissipates into hydraulic fluid. ...
The Python code for the IRIS DMC's Ground Motion Visualization (GMV) data product. GMV is a video-based IRIS DMC data product that illustrates how seismic waves travel away from an earthquake location by animating the normalized recorded wave amplitudes
