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!
do s waves move the earths crust up or down
No. It records the ground movements.
yes
No.
A seismograph.
P-waves are the first seismic waves to arrive at a seismograph station.
"Shake, Rattle, and Roll". But seriously folks, it's called a "seismogram".

Seismograph
Seismic waves are measured by seismographs, geophones, hydrophones and accelerometers.

Scientists use an insrument with the name of a seismograph
Seismometer (or seismograph) and it measure seismic waves
seismometer, also known as a seismograph. which record seismic waves
The seismograph measured the intensity of the seismic waves
A seismometer or seismograph
The first waves to arrive at a seismograph station are primary waves, or P waves.
A seismograph.
Seismograph ;) (listen in your science class!)
A seismometer (or the older device called a seismograph) records the seismic waves from earth tremors.+++There is a difference there: a seismometer would simply register instant vibration; a seismograph records the vibrations with time so shows the whole picture.
a seismograph is a device that records ground movements caused by seismic waves
