Seismic waves are measured by seismographs, geophones, hydrophones and accelerometers.
seismic waves
A seismograph is one such instrument...there might be others.
With a seismograph. While professional seismographs use electronic transducers to detect small movements of a mass, a very simple one can be built with a simple pendulum having a pen attached to it to draw its movements on a sheet of paper.
The most common such devices are the seismographs and Hydraphones.

earthquakes are measured by seismic waves so scientists use a seismograph. there are a bunch of seismographs at a station and each one records the same stuff according to the p, s, and surface waves.

An area of Earth's surface where seismographs cannot detect an earthquake after waves has passed.
The most common such devices are the seismographs and Hydraphones.
Scientists use a recording instrument called a seismograph to detect ground motions caused by seismic waves from earthquakes.
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
Seismometer (or seismograph) and it measure seismic waves
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!
