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.
At least three seismograph stations are needed to triangulate the exact location of an earthquake's epicenter. By comparing the arrival times of the seismic waves at different stations, scientists can pinpoint the epicenter where these intersect. More stations can provide a more accurate and precise location.
Magnetism is crucial for many aspects of modern life, including generating electricity, powering devices like electric motors and generators, and enabling technologies like MRI machines for medical imaging. It plays a key role in numerous everyday objects like speakers, credit cards, and magnetic storage devices. Without magnetism, our lives would lack the convenience and functionality that many of us take for granted.
You can measure relative heat with a thermometer.The units of temperature (degrees Celsius / kelvins) indicate molecular heat content, while the actual heat energy being generated, added, or removed is measured in joules(newton-meters), a unit of work.
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

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

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.
Yes. Earthquakes occur most often along fault lines. There are also many different devices (seismograph) that sense seismic waves and can predict earthquakes.
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.
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!
None. Valves are not used. Integrated circuits are now the mainstay of most electronic devices.
While the exact number is not known it is somewhere in the low thousands.
At least three. China, America, and Japan.
