Seismology
accelerometer
Earth science; Seismology
A sensor whose output is almost directly proportional to ground acceleration. The conventional strong-motion accelerometer is a simple, nearly critically damped oscillator having a natural frequency ...
impulse response function
Earth science; Seismology
A mathematical representation of an impulsive signal. By taking the Fourier transform of the impulse response of the system, you obtain the frequency response function.
linear filter system
Earth science; Seismology
A means of describing seismic waves (ground displacement) in terms of the source function, propagating function and the instrument recording function.
airy phase
Earth science; Seismology
A local minimum at 20 sec and 200 sec on group velocity curves that result from a large amount of energy arriving at the same time.
swarm of earthquakes
Earth science; Seismology
A series of earthquakes in the same locality, no one earthquake being of outstanding size.
geodimeter
Earth science; Seismology
A surveying instrument to measure the distance between two points on the Earth's surface.
