Seismographs cannot measure volcanoes. When you research about seismographs, it may show thing about volcanoes. This is because right before a volcano erupts, it can cause little earthquakes and seismographs measure earthquakes!
Multiple seismographs
Seismographs record the arrival time and amplitude of seismic waves. They can be used to locate the earthquakes epicentre and estimate the earthquake's magnitude. Please see the related question.
seismogram are the records or paper copies that are produced by seismographs used to calculate the location and magnitude of an earthquack
No, seismographs cannot predict hurricane intensity. It can only detect and predict any ground movement
this is where the seismic waves recorded; measures vertical earth motion
traces of amptified electronically record ground motion made by seismographis
The motion of the earthquakes around you.

when waves from an earthquake reach the instrament, the inertia of the weight keeps it stationary, while earth and the support vibrate. Seismographs amplify and electronically record ground motion.
it records the frequency of the earthquake !
seismographs
They are scientists which monitor, record and forecast about earthquakes
Well you know when you write a sentence, the paper stays in one place while your hand moves the pen. But in a seismograph, it's the pen that remains stationary while the paper moves. Why is this? All seismographs make use of a basic principle of physics: Whether it is moving or at rest, every object resists any change to its motion. A seismograph's heavy weight resists motion during a quake. But the rest of the seismograph is anchored to the ground and vibrates when seismic waves arrive.
Seismic waves are measured by seismographs, geophones, hydrophones and accelerometers.
