7 The seismometer has one vertical component and two horizontal components.
8 The model JD-2F bore-hole seismometer has been successfully developed on the basis of the model JD-2 deep well seismometer after improving technology and introducing electronic feedback technology.
9 The accurate measurement of seismometer transfer function is important to interpret and use of seismographic observation data.
10 Schofield marches down the hall, grabs a seismometer and an oscilloscope and hauls them into a van.
11 The ground motion at each seismometer is amplified and recorded electronically at a central recording site.
12 Mark Zumberge: Basically a seismometer is a box with a spring with a mass hanging inside, and as the ground shakes the mass goes up and down.
13 Zumberge said a conventional seismometer records how its mass is displaced by these waves of seismic energy with electric circuit boards.
14 How is the movement of the seismometer converted into a seismogram?

16 A small lander, equipped with a seismometer, could detect the rumblings of underground liquids.
17 Orientation is very important for a seismometer, whether it is installed on surface or in borehole.
18 A seismometer is a seismograph whose physical constants are so well known.
19 We've come up with a way, using optical fibers, to bring laser light to and from the seismometer, to make very precise measurements of the vibrations of the mass in our seismometer.
