2016年3月20日 · P-waves are the fastest of the three seismic waves. Secondary (or S-waves) S-waves cannot travel through air or water, only through solids, but they have a larger amplitude (this is the height of a wave, measured from the highest point to the middle line) so are more destructive in the case of an earthquake.

2016年3月20日 · There are three type of seismic wave. Primary (P) waves are longitudinal, the fastest, the least destructive (lowest amplitude) and they can travel through water, air and solids. Secondary (S) waves are transverse, medium speed (relative to the others), second most destructive and can only travel through solids. Surface waves have two different types (love …

2015年12月6日 · P-waves, S-waves, L-waves They are distinguished by the manner they travel and their speed. P-waves or primary waves are the fastest waves. It moves the earth in a push-pull motion. It travels through solids, liquids, and gases. S-waves or secondary waves not as fast as p-waves. It moves the earth side by side. It can only travel through solids. L-waves or …

2018年4月5日 · Actually, there are four main types of seismic waves. All of them involve contractions in some direction. Generally, the impact can be felt in all directions, but you can take a look at the above image for reference as to whatever causes the seismic wave.

2015年9月27日 · Here's a visual summary of all the waves: Here's a seismogram measurement of the different types of waves over time from an earthquake: And here's a cool depiction of what types of waves that would be measurable from different parts of the world relative to the epicenter of an earthquake:

2016年3月20日 · Primary waves Unlike the other seismic waves, Primary waves move through solids liquids. They are also the fastest type of wave, however, due to their lower amplitude, they are the least destructive. Secondary waves are the second fastest, second most destructive and have the second highest amplitude but only travel through solids.

2016年8月14日 · What is different about how the seismic waves generated by earthquakes travel through the inner core than any other layer?

2017年12月24日 · It is the differences in relative densities of solids and liquids that affects the direction and velocity of seismic waves. Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature, and pressure of the media through which seismic waves pass. Seismic waves travel more quickly through denser …

2018年4月8日 · Earthquakes produce two kinds of seismic waves: he longitudinal primary waves (called P waves) and the transverse secondary waves (called S waves). Both S waves and P waves travel through Earth’s crust and mantle, but at different speeds; the P waves are always faster than the S waves, but their exact speeds depend on depth and location. For the …

2017年12月15日 · P Wave: ⌁ The first waves to arrive from the earthquake are "Primary Waves." ⌁They are seismic waves that compress and expand the ground like an accordion. ⌁ They can move through solids & liquids.
