Seismometers or Seismographs are instruments that measure motions of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions, and other seismic sources.
Seisometers are used to measure how much the ground moves, but the only real way to detect them is to look at previous records as to how long it has been since an earthquake; if it a long time, an earthquake could happen soon.

they measure earthquake with the seismograph using the richter scale to determine the size of the seismic (shock waves) they can also use the mercalli scale to visually see how large it was sorry dont know about volcanoes hope this helps x
Depends on the size of the earthquake that causes it. ADDED: Also of course, the topography and altitude of the coast; and the nature of any barrier such as mangrove swamps, which are effective breakwaters.
No. Size does not necessarily affect the magnitude of an earthquake. In fact, a deep earthquake will have less of an effect on the surface than a shallow earthquake of the same magnitude.

Scientists measure the magnitude (energy) of an earthquake using a seismograph (sort of sensitive pendulum that records the shaking of the earth).
The extent or size of an earthquake at a particular time is determined from the logarithm of the amplitude of waves that are recorded by a seismograph. The magnitude and intensity of the earthquake is measured on a Richter scale.

The word seismograph is the old fashioned term for a seismometer. They both perform the same function (recording the amplitude, frequency and duration of seismic waves) however they record the data differently. Seismometers record the data digitally, whereas a seismograph plotted the data directly onto a roll of graph paper. Previous answer: A Seismometer is something used to record motions of the ground. Such as earthquakes and nuclear explosions. So they can measure the size of the explosions.

Seismic waves are the vibrations from earthquakes that travel through the Earth; they are recorded on instruments called seismographs. Seismographs record a zig-zag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs, which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. The time, locations, and magnitude of an earthquake can be determined from the data recorded by seismograph stations. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
- The magnitude of an earthquake can be measured on a scale called Richter scale.- A Richter scale assigns a number each earthquake. This is also known as the Richter magnitude scale.
The term magnitude is used to describe the size of an earthquake.

The Earthquake in Japan was a 9.0 magnitude.
