The 18th century.
The seismograph for a larger earthquake would show stronger and more prolonged seismic waves compared to a smaller earthquake. The amplitude and duration of the seismic waves recorded by the seismograph would be greater for the larger earthquake.
The distance from an earthquake epicenter can be calculated using the time difference between the arrival of P-waves and S-waves at a seismograph station. By measuring this time lag and using the known velocity of seismic waves through the Earth's interior, the distance can be estimated. The greater the time lag between the arrival of the P-wave and S-wave, the farther the seismograph station is from the earthquake epicenter.
Yes, you can make a simple seismograph using a cup filled with sand or rice, a pen or pencil with a weight attached to the end, and a sturdy base. When an earthquake occurs, the base will shake while the weight on the pen or pencil remains still, creating a record of the ground motion in the sand or rice.
The energy released by earthquakes take the form of seismic waves which travel through the ground. These are detected by a seismograph. Based on the amplitude of the seismic waves measured by the seismograph the earthquakes strength can be calculated (to give a value on the Richter scale). Large earthquakes can cause permanent displacements / deformation at the Earth's surface whereby the change in position of an object can be detected using GPS.
Earthquakes are detected by using a seismograph
using a seismograph
they do it by using a seismograph
in the 17th century
Fibonacci introduced the Arabic number system to Europe in the thirteenth century (in the 1200s AD). At first the Europeans didn't take to the system, but later found it was much easier than using Roman numerals and the abacus.
It started in the nineteenth century.
19th century.....sorry this is all i know....
A seismograph is the machine that measures the strength of energy waves, such as seismic waves, generated by earthquakes. The data recorded on the seismograph is used to determine the earthquake's magnitude.
In the 15th century
Scientists use seismographs to monitor earthquakes. Though, a seismograph merely registers an earthquake. By using at least three seismograph stations, and using triangulation, the epicentre of the earthquake is able to be plotted.
In the 21st century (now)
Royal houses and priests began the use by 1000BC. However,ordinary people start using from about 5th century AD
Well.... seismology is the study of earthquakes seismologists are the scientists who study earthquakes seismograph is how they measure earthquakes.... So using that, the root seismos is Greek for earthquake!
