How would the seismograph for the two earthquake compare?
By using friction. Without it, they wouldn't have anything so the two will have also faults along the friction
Earthquakes are detected by what barometer Richter scale seismograph global positioning system?
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.
How are earthquakes detected and measured?
Earthquakes are detected by using a seismograph
What is the difference of the P waves and S waves used to locate an earthquake's epicenter?
P waves, also called primary waves, are the first waves to be registered on a seismograph. The S waves, or secondary waves, are the second and slower wave to register on the seismograph. When locating an earthquakes epicenter seismologists take the first reading of the P wave, and then take the reading from the S wave. At the station of where the earthquake was recorded, seismologists draw a large circle from where the earthquakes epicenter could be. TO exactly located the earthquakes epicenter there needs to be at least 3 dfferent staions where the earthquake hit to determine its epicenter using the S and P time interval.
How does seismographs detect and record seismic waves?
Well you know when you write a sentence, the paper stays in one place while your hand moves the pen. But in a seismograph, it's the pen that remains stationary while the paper moves. Why is this? All seismographs make use of a basic principle of physics: Whether it is moving or at rest, every object resists any change to its motion. A seismograph's heavy weight resists motion during a quake. But the rest of the seismograph is anchored to the ground and vibrates when seismic waves arrive.
How do scientists read earthquakes?
using a seismograph
How can scientists tell where the earthquake happend?
they do it by using a seismograph
When did composers start using dynamics?
in the 17th century
When did Europe start using Arabic numerals?
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.
When did they first start using fashion?
It started in the nineteenth century.
What machine measures the strength of the energy waves sent out from an earthquake?
An earthquake is measured using a machine called a seismograph. The magnitude of an earthquake was measured at one time using the Richter magnitude scale., but that has been superseded by the moment magnitude scale (MMS). Subjective impressions of the intensity of an earthquake is sometimes reported using a modified Mercalli scale.
How does a seismograph measure ground movement?
Using very sensitive accelerometers.
In what century did people start using plus and minus signs?
19th century.....sorry this is all i know....
When did they start using lead in sail boat keels?
In the 15th century
Do seismographs monitor earthquakes?
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.
When do people start using maglev trains the most?
In the 21st century (now)
What does the prefix seis mean in seismograph?
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!
