What is seismology.

Seismic wave, vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface. Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within the Earth, whereas the other two, called surfaceseismology. 1 ENTRIES FOUND: seismology (noun) seismology /saɪz ˈ mɑːləʤi/ noun. Britannica Dictionary definition of SEISMOLOGY. [noncount] : the scientific study of earthquakes.What Is Seismology? Seismology is the study of earthquakes and seismic waves that move through and around the earth. A seismologist is a scientist who studies earthquakes and seismic waves. What Are Seismic Waves? Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion.An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.View all Stories.

The study of earthquakes and the structure of the earth, by both naturally and artificially generated seismic waves. An earthquake is defined as the vibration of the Earth’s surface by sound or shock waves usually generated by the energy released from rocks rupturing under stress or by friction between moving rock materials at or mostly below Earth’s surface.

A seismic wave is a mechanical wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake ), volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy.

Seismometers are instruments that measure and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources.

Seismic noise. In geophysics, geology, civil engineering, and related disciplines, seismic noise is a generic name for a relatively persistent vibration of the ground, due to a multitude of causes, that is often a non-interpretable or unwanted component of signals recorded by seismometers . Physically, seismic noise arises primarily due to ...Uses seismic and geophysical instruments and tools and interprets the data collected; Establishes the existence of fault lines and the direction, motion and stress of the earth's movements before, during and after and earthquake; Creates maps and charts indicating the areas of seismic risk to existing proposed construction and development plansSeismic impulses in the frequency range of 0.1 Hz to 1 Hz (periods of 10 seconds to 1 second) can be impeded by a microseism, a natural background type of noise. Some of these may be produced by local factors such as traffic, rainfall, or wind impact on trees, but the activity of storm waves and strong swells at sea is a significant contributorHelioseismology is the study of the solar interior using observations of waves on the Sun's surface.

Richter scale, widely used quantitative measure of an earthquake’s magnitude (size), devised in 1935 by American seismologists Charles F. Richter and Beno Gutenberg. Magnitude is determined using the logarithm of the amplitude (height) of the largest seismic wave calibrated to a scale by a seismograph.
