There are 14838 seismograph stations of which 11559 are open and 3279 are closed, as of 11th March at 2030 UTC/GMT. Source: United States Geographical Survey.
A seismograph as important today because it can monitor movement of the ground before an earthquake happens and it can inform people. That way you can send help fast and save many peoples lives
It takes 3 stations.
At least three.Please see the related question for an explanation as to why.A minimum of three seismograph or seismometer stations are required to locate the epicentre of an earthquake.
A seismograph measures and records the waves generated by earthquakes and similar seismic events.Earlier devices had separate measuring (seismometer) and recording instruments.

there are many devices, such as a seismometer. copy and paste URL below to your address bar for more info. http://en.wikipedia.org/wiki/Seismograph
Most pressure measuring devices have elastic members for sensing pressure at the primary stage elastic members are of many types and convert the pressure into mechanical displacement which is later converted into an electrical form using a secondary transducer.These devices are known as force summing devices

how many seismograph stations benifit earthquake victims after the damage occurs
Many modern devices can be used for communication hence the reason the industry is IT (Information technology). but as for ones dedicated to communication we have...... Cellular phones, Fax machines, Personal computers. Those are some of the most common devices, I could list many more but that's three of them.
It is a "Seismograph". It "listens" to the vibrations, and draws out (with an inked needle) the tremors onto a piece of paper. A seismometer is what measures and records earthquakes. Many modern seismometers send their data directly electronically to computers, which record and automatically analyze that data instead of using the inked needle on paper.
Yes. Earthquakes occur most often along fault lines. There are also many different devices (seismograph) that sense seismic waves and can predict earthquakes.
Most modern SCSI buses support a total of 16 devices, while older SCSI implementations usually support only eight devices.
seismograph is one instrument that could measure earthquakes and volcanoes etc but seismograph is many times use at earthquake!
