What does seismic mean in a sentence?
1 : of, subject to, or caused by an earthquake also : of or relating to an earth vibration caused by something else (such as an explosion or the impact of a meteorite) 2 : of or relating to a vibration on a celestial body (such as the moon) comparable to a seismic event on earth.
How do you use seismic wave in a sentence?
These seismic waves in the crust are what people feel when they experience an earthquake. For three years, the seismometers recorded how seismic waves from hundreds of earthquakes worldwide bounced through the mantle.
What’s an example of seismic?
The definition of seismic is relating to or subject to earthquakes or man-made tremors. An example of something seismic is the movement of land during an earthquake; seismic movement. Of, subject to, or caused by an earthquake or earth vibration.
What is a seismic activity?
Seismic activity (from the Greek seismos, earthquake) is the frequency and severity of earthquakes in a given region. Most of the Earth’s seismic activity is concentrated at the margins of Earth’s crustal plates, where plates pull apart, slide past one another or converge.
What is seismology used for?
1 Concept. Seismology is the science of earthquakes to study the causes and effects of minute pulsation to most catastrophic natural phenomenon inside the earth. The method can be classified broadly into two major divisions depending on the energy source of the seismic waves.
How do seismic waves move?
Explain that earthquake waves move particles of material in different ways: whereas, compressional waves create a back and forth motion parallel to the direction of the waves, shear waves create a back and forth motion perpendicular to the direction of the waves.
How do you use the word seismic?
Seismic in a Sentence 🔉
- Seismic tests were conducted to determine the force of the earthquake.
- Seismic waves caused by the earthquake caused a tsunami on the island shore.
- Conducting hi-tech seismic surveys, the scientists were able to predict an upcoming quake.
What are P and S waves?
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. Both P and S waves travel outward from an earthquake focus inside the earth.
What are the different types of seismic activity?
There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.
What is earthquake why it is called seismic activity?
In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests.
