John Milne invented the seismograph in 1880
A seismometer is an instrument that is anchored to the ground and records the Earth's movements, specifically seismic waves caused by earthquakes and other sources of ground motion.
A seismogram is a record of ground motion produced by seismic waves from an earthquake or another source. It typically shows the amplitude and frequency of the seismic waves over time, helping seismologists analyze and understand the earthquake's characteristics.
A seismograph detects and records vibrations (seismic waves) caused by earthquakes or other sources. It consists of a mass suspended on a spring that moves with the ground motion, which is then amplified and recorded on a drum or digitally. The resulting data helps scientists analyze the intensity, frequency, and location of seismic events.
Perhaps the earliest seismograph was invented in China A.D. 136 by a m an named Choko.
The rain alarm was invented by Andrew Grimes. It is a device that alerts users when rain is approaching so they can take necessary precautions.
the seismograph was invented in Chicago, 1800.
It's a seismograph.
Geologists use seismographs. They try to see when an earthquake is going to occur.
A seismogram is a record of an earthquake that's obtained from a seismic instrument. It's in the form of a graph.
Why, a seismographer of course! Seriously though... Anyone who studies, or monitors for, earthquakes, volcanoes, & other such phenomena would use one.
The correct spelling (transposed) is seismograph(measures and records seismic activity).
That would be a secondary, or 'S' wave. Moving in a snakelike movement, this wave has to travel a farther distance, so it takes longer to reach the recording equipment.
a siesmic wave is a wave that travels through the earth. there are two MAIN types, P and S waves. a siesmograph shows the type of wave and how far away it is from that point.
