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 are the four devices used to detect a possible earthquake?
The four devices commonly used to detect a possible earthquake are seismometers, accelerometers, tiltmeters, and GPS receivers. Seismometers measure the ground motion caused by seismic waves, accelerometers measure the acceleration of ground shaking, tiltmeters measure changes in the tilt of the ground surface, and GPS receivers measure precise ground displacements. These devices work together to provide valuable information for earthquake detection and monitoring.
Did the bay bridge fall in 1989 because of an earthquake?
Extreme metal stress from the lateral motion of the earthquake. which caused the collapse of the upper tiers.
Which earthquake waves travel through matter with a push pull motion?
P-waves.
What magnitude scale measures ground motion?
The Richter Scale is what measures the ground motion from an earthquake.
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 detects the motion of ground waves in an Earthquake?
seismometer
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 types of seismic waves produce the most damage during an earthquake?
Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
What measures the length of the path that an object follows during its motion?
Motion
What is shaking and ground rupture?
Shaking and Ground rupture are the effects of earthquake. Ground shaking is the disruptive up and down and sideways motion experienced during an earthquake. And, Ground Rupture is the creation of new or the renewed movements of old fractures, oftentimes with the two blocks on both sides moving in opposite directions.
Seismographs?
this is where the seismic waves recorded; measures vertical earth motion
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
How is the strength of an earthquake measured?
You use a seismograph to measure the strength of an earthquake.
