To do with earthquakes. magnitude Richter seismometer seismograph
refers to a geophysical technique using low frequency sound waves to determine the subsurface structure of sedimentary rocks.
Pertaining to earthquake activity.
Related to mechanical vibration within the Earth or Moon resulting from, for example, impact of meteoroids on the surface.
is the adjective derived from the noun seism, which is derived from the Greek meaning earthquake.137 In the context of disaster, seismic means related to vibrations of the earth and its crust. Such vibrations are produced either by movement of the tectonic plates of the earth, volcanic eruptions, or from artifical causes as result from explosions.138 (Secondary event includes tsunamis.)
related to earthquakes All new buildings were constructed to withstand moderate seismic activity. seismology (n), seismograph (n), seismographer (n)
relating to or caused by an earthquake.
subject to or caused by an earthquake or earth vibration
A tool for identifying oil or gas accumulations. Energy waves or sound waves are sent into the earth, and the wave reflections are recorded. Results can indicate the type, size, shape and depth of subsurface rock formations. 2D seismic provides two-dimensional pictures, and 3D seismic provides three-dimensional pictures.
In terms of mezzanines it is the ability of the mezzanine to withstand movement caused by earthquakes, earth vibrations or earth movements.
Either two-dimensional or three-dimensional, computer assisted processing of sedimentary structures, assist in planning drilling programs.
Refers to earth vibrations, such as those created by earthquakes, usually related to movement on faults. Also applies to man-made acoustic (sound) waves used to analyze the structure of the subsurface, for resource exploration and environmental studies. Figure
Seismic - Pertaining to an earthquake or Earth vibration, including those artificially induced.
having to do with earthquakes
The seismic process records the time taken for a sound wave to travel from the surface of the earth to a sub-surface rock layer and then back again. The data collected can be processed to provide a pictorial representation of sub-surface rock layers and is used extensively in hydrocarbon exploration and production. Old ‘single fold’ seismic shot in the 1960’s is greatly inferior to modern ‘multi-fold’ seismic.
Pertaining to earthquakes or earth vibrations, including those that are man-made, e.g., explosions and underground nuclear blasts.
Pertaining to or produced by earthquakes.
related to a vibration caused by activity within the earth, often an earthquake.
pertaining to vibrations in the Earth, such as earthquakes; or to equipment or methods used to create Earth vibrations, such as exploding dynamite in oil exploration.
A tool for identifying underground accumulations of oil or gas by sending energy waves or sound waves into the earth and recording the wave reflections. Results indicate the type, size, shape and depth of subsurface rock formations. 2-D seismic provides two-dimensional information while 3-D creates three-dimensional pictures. 4-C, or four-component, seismic is a developing technology that utilizes measurement and interpretation of shear wave data. 4-C seismic improves the resolution of seismic images below shallow gas deposits.
The transmission of shock waves into the earth then measuring the returned waves recorded by a seismograph. The shock waves are produced by exploding charges of dynamite in shallow holes drilled for this purpose or by trucks that vibrate the ground. Upon striking rock formations, the waves are reflected back to the seismograph. The time lapse is a measure of the depth of the formation. Spud: This term refers to the point in time at which the drill bit begins to turn into the earth and drilling actually starts. Syncline A U or bowl-shaped: A geologic structure, not favorable to the accumulation of oil or gas because of the tendency of the latter to rise in the structure until further escape is blocked. go back
a word describing the nature or characteristic of a given phenomenon or place as being of, subject to or caused by an earthquake.
Seismic means pertaining to earthquakes.
Pertaining to waves of elastic energy, such as that transmitted by P-waves and S-waves, in the frequency range of approximately 1 to 100 Hz. Seismic energy is studied by scientists to interpret the composition, fluid content, extent and geometry of rocks in the subsurface. "Seismic," used as an adjective, is preferable to "seismics," although "seismics" is used commonly as a noun.
Earth vibrations relating to an earthquake or explosion.
