seismo-, seism-, -seism, -seisms, -seisma, -seismically, -seismical, -seismal, -seismic

(Greek: to move back and forth; to shake, to move violently; earthquake)

aseism, aseismic
1. Resistant to the destructive effects of earthquakes.
2. No earthquake; without shaking (as exists with an earthquake).

Data on hydroseisms in wells are published annually by the U.S. Coast and Geodetic Survey.

Fault slips include aseismic creep and transient slip

Slip on faults occurs as a combination of relatively continuous aseismic creep and transient slip events. These transient events occur as earthquakes radiating seismic waves, and also as aseismic events with characteristic time scales of days to years.

A better understanding of the physical factors that control the relative amount and location of seismic and aseismic slip is a key goal in the study of fault mechanics and, in particular, can affect assessments of reginal seismic and tsunami hazards.

A specialist in the measuring of starquakes.
1. Measuring starquakes.
2. The study of the interior of stars by means of oscillations on their surfaces.

The oscillations studied by asterioseismologists are driven by thermal energy converted into kinetic energy of pulsation. This process is similar to what goes on with any heat engine, in which heat is absorbed in the high temperature phase of oscillation and emitted when the temperature is low.

The star on which this technique has been applied most effectively is the Sun, where the technique is known as helioseismology.

The stars that asteroseismologists study are constantly vibrating, sending compression waves richocheting through their interiors to the surface, where they manifest as changes in the stars’ brightness.

A reference to the pressure wave generated by an earthquake. The Richter scale is a logarithmic scale for measuring the magnitude of the baroseismic wave at a particular point in space, usually estimated at the surface above the seismic source.
baryseisma, baryseismic
An earthquake of deep origin recordable at seismographic stations the world over.
An earthquake occurring at very deep levels in the earth.
bradyseism, bradyseismic
The slow upward and downward motion of the earth’s crust.
cineseismography, kineseismography
1. A technique for measuring movements of the body by continuous photographic recording of shaking or vibration.
2. A photographic system for recording and measuring abnormal involuntary movements; its great advantage is that it obviates the need to attach any devices to the subject.
coseism, coseismic
A line drawn around an epicenter through all the points affected by the same seismic shock.
geoseism (s) (noun), geoseisms (pl)
Another term for an earthquake: Lynn learned that when there were tremors within the planet, it was also called a geoseism.
1. The study of sun quakes by observing the structure, composition, and dynamics of the sun from indirect observations of acoustic waves on the sun's surface.
2. The study of the sun's internal structure using observations of the frequencies and strengths of normal mode oscillations detected at the surface by their Doppler shifts.

Such vibrations were first discovered in the 1960s by researchers at the California Institute of Technology.

1. All seismically induced water-level fluctuations other than tsunamis.
2. Applies to seismically induced fluctuations in wells, streams, lakes, ponds, and reservoirs.
3. Groundwater level changes in response to earthquake activity.
4. The role of water in the generation of intraplate seismicity.

When a massive undersea earthquake in the Indian Ocean generated deadly tsunamis December, 2005, some groundwater monitoring wells recorded the catastrophic event in the United States.

Data that includes both the charts that record hydroseisms and the information taken from the charts.
Hydroseism (fluctuations in wells, streams, lakes, ponds, and reservoirs) recorded at an expanded time scale.
1. An interval between earthquake activities.
2. Between one seismic action and another one.

Here is a perspective about the history of earthquakes.
