Yes, and when one is being off due to repairs and/or tunning, other remains on. All the seismographs are always on, and were has to be repaired and/or tunned, there is always a backup one on.

with some luck they can help predict earthqueks and evacuate people it time.
The three types of the Seismographs are: - magnitude,shaking and focus.
Yes, all the time. Granted, most of them appear slightly on most seismographs, and are hence "known," but these minor tremors cannot be felt.
The two types of seismographs are analog seismographs, which use a pen and rotating drum to record seismic activity on paper, and digital seismographs, which use electronic sensors to detect and record seismic waves digitally.

seismogram are the records or paper copies that are produced by seismographs used to calculate the location and magnitude of an earthquack
Yes, there are seismographs in Bakersfield, California, which is located in a seismically active region. Seismographs are used to detect and record seismic activity such as earthquakes. It is important to have seismographs in this area for monitoring and early warning purposes.
Scientists developed seismographs in the late 19th century. The first seismograph was invented by John Milne in 1880.
