Wave Velocity • Differences in velocity allow mapping of the Earth’s interior. ospedali privati lavora con noi
What are the Effects of Earthquakes? U.S. Geological Survey
WebApr 9, 2024 · Seismic waves generally travel much shorter distances on the West Coast than on the East Coast because: A. earthquakes are more frequent on the West Coast. B. the soil composition is different in the two regions. C. the earthquakes are of a greater intensity on the East Coast. D. communities are better prepared for earthquakes on the West Coast. WebThe P wave is designated the primary preliminary wave because it is the first to arrive at a seismic station after an earthquake. It travels at a speed usually less than 6 kilometers per second in the Earth's crust and jumps to 13 kilometers per second through the core. The S wave is the secondary preliminary wave to be recorded. WebAn earthquake is described as the shaking or vibration of the tectonic plates which float on the mantle, and oftentimes, hazards of earthquakes accompany them. Some earthquakes are tiny in magnitude, while others can cause colossal disasters.
