A seismograph is a device that measures and records seismic waves produced by earthquakes, volcanic activity, or explosions. It consists of a mass suspended from a frame that moves with the ground motion, and a pen attached to the mass that records the motion on a rotating drum or electronic display.
A seismogragh is a sensative instrument that records seismic waves.
A seismogragh and/or seismometer.
The distance to the epicentre of an earthquake and it's magnitude.
the exact distance between earth and moon
The ground shakes moving a needle which is then used to see how strong it was based on how much the needle moved.
A seismograph uses electromagnetic sensors to measure seismic waves in order to detect earthquakes that are too small to feel, as well as detecting and tracking other phenomena.
A seismograph is a device that detects and measures the magnitude and duration of seismic waves caused by earthquakes and other sources of ground motion. It records the ground motion as a seismogram, which helps seismologists analyze and understand the characteristics of earthquakes.
A seismograph is a device that records the motion of the ground resulting from seismic waves caused by earthquakes, volcanic eruptions, or other seismic sources. It consists of a moving mass suspended on a spring that remains relatively static during ground motion, allowing the recording of seismic waves.
