When were seismic graphs invented?
Seismic graphs were first used in the early 20th century, with the first recorded reflection seismograph shot taken in 1921. The use of seismic graphs revolutionized the field of geophysics by allowing scientists to study the subsurface structure of the Earth by analyzing reflected seismic waves.
What Instrument measures the density of an earthquake?
A seismometer is the instrument that measures the density of an earthquake, which is done by detecting and recording the vibrations produced by seismic waves. These measurements help scientists determine the magnitude and intensity of an earthquake.
What type of seismic waves that arrive at the surface first and move by compressing and expanding the ground like an accordion?
Primary waves (P-waves) are the seismic waves that arrive at the surface first and move by compressing and expanding the ground, similar to an accordion. They are the fastest seismic waves and can travel through solids, liquids, and gases.
Which seismic waves travel the fastest?
Primary waves (P-waves) are the fastest seismic waves and are the first to be detected after an earthquake. They are able to travel through solid rock, liquid, and gas, making them the fastest seismic waves.
What type of seismic waves that arrived at the surface first and move by compressing and expanding the ground like an accordion are called?
P Wave
When was the first instrument invented?
it was invented in 1789
What was the first instrument to ever record an earthquake?
The first instrument to ever record an earthquake was the seismograph, invented by John Milne in 1880. It consisted of a rotating drum that recorded ground motion caused by seismic waves, allowing for the measurement and analysis of earthquakes.
