1 In seismic stations throughout the world, modern digital seismometers took their place.

2 First, the new digital seismometers had unleashed upon geophysicists a flood of sensitive, accessible data.

3 As of 1977, fewer than ten digital seismometers were deployed around the globe.

4 "I know that seismometer very well," Rocard said.

5 How can I make my own seismometer?

6 Currently, scientists rely on a global seismometer network to detect earthquakes that might trigger tsunamis.

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?

15 The seismometer pattern layout design with illumination analysis can avoid the errors from hypothesis of homogeneous media in its conventional system design.

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.

20 We produced the new type of digitizer(EDAS-24GN) and broadband borehole seismometer in 2010.

21 On condition that the open-loop parameters are given, the loop filter of feedback seismometer with a velocity transducer is one of the key factors of effecting seismometer main technical performances.

22 At present, three kinds of seismographs are used at Chinese seismic stations. They are the direct-coupled seismometer, the galvanometric seismograph, and the electronic seismograph.

23 A method has been developed to obtain analytically the seismometer parameters in time domain based on the step calibration function.

24 There are a few Quake Catchers in the Central Asian nations Kyrgyzstan and Tajikistan -- places where "it would be pretty difficult to install a [traditional] seismometer."

25 With regard to extending the upper limit for dynamic range of seismometer,[] the merits and demerits of the loop filter are discussed.

26 Geophysicist Mark Zumberge at the Scripps Institution of Oceanography is developing a new breed of seismometer to get a better look inside the Earth.

27 Orientation relying on magnitism must have error if there is ferromagnetism around the seismometer.
