What measures the ground motion during an earthquake?
Seismograph.
How do seismographs record ground motion?
As the drum rotates slowly, the pen draws a straight line on paper wrapped tightly around the drum.Made by -Amy[;Why so seruis?TM
Earthquakes are measured with an instrument called a?
A seismogram traces the earthquakes motion that is created by the seismograph and the seismograph records vibrations in the ground and determines the location and strength of an earthquake.
What are Seismic hazard maps used?
When building a house, regional seismic hazard maps are used to find the best (or the worst) place to locate for earthquake shaking. Although greatly confused with its sister, seismic risk, seismic hazard is the study of expected earthquake ground motions at any point on the earth.
What do study Seismology?
A seismologist studies earthquakes and the propagation of earthquake waves (more correctly termed seismic waves) through the Earth and what these can tell us about the structure of the Earth (much like dolphins use sonar to see objects underwater).Earthquakes.Earthquakes and seismic activity.
How does a seismograph records a earthquake?
when waves from an earthquake reach the instrament, the inertia of the weight keeps it stationary, while earth and the support vibrate. Seismographs amplify and electronically record ground motion.
Seismographs?
this is where the seismic waves recorded; measures vertical earth motion
seismograms?
traces of amptified electronically record ground motion made by seismographis
What magnitude scale measures ground motion?
The Richter Scale is what measures the ground motion from an earthquake.
What detects the motion of ground waves in an Earthquake?
seismometer
What measures the ground motion during an earthquake?
Seismograph.
How many times greater is the maximum ground motion of a magnitude 5 earthquake compared with that of a magnitude 3 earthquake?
The maximum ground motion of a magnitude 5 earthquake is 100 times larger than a magnitude 3 earthquake.
What is the difference in strength between a 7.0 magnitude earthquake and a 9.0 magnitude earthquake?
-3.0 magnitude or if you want the ground motion: Each time the magnitude increases by one unit, the measured ground motion becomes 10 times larger. For example, an earthquake with a magnitude of 5.0 on the Richter scale will produce 10 times as much ground motion as an earthquake with a magnitude of 4.0. Furthermore, an earthquake with a magnitude of 6.0 will produce 100 times as much ground motion (10 × 10) as an earthquake with a magnitude of 4.0.
What can move the ground with a rolling up-and-down motion?
An earthquake.
What two things can a seismometer detect?
Ground motion, earthquakes and nuclear explosions for example.
How much more ground motion is produced by an earthquake of magnitude 7.0 than by an earthquake of magnitude 4.0?
0.3 magnitude
How much more ground motion is produced by an earthquake of magnitude 7.0 than by an earthquake magnitude 4.0?
0.3 magnitude
