What do you need to completely describe where an earthquake started?
Scientists use seismographs to measure thousands of earthquakes, large and small, every year. Some seismographs can detect ground movements as small as one hundred-millionth of a centimeter. The recording produced by a seismograph is called seismogram. By studying seismograms, scientist can determine the locations and strengths of earthquakes.
What are the disadvantages of seismographs?
They do not predict earthquakes.
What are the two types of seismographs?
horizontal and verticalseismographs
Which instruments Used to record intensity of earthquakes?
seismographs
What do scientist us to measure tectonic plate movement?
Sizemec waves
How many seismographs are needed to detect an earthquake?
three
What can be used to detect hidden faults?
They can use seismographs
Can seismographs predict hurricane intensity?
No, seismographs cannot predict hurricane intensity. It can only detect and predict any ground movement
How are Seismographs data used?
Seismographs and fault-monitoring devices provide data used to map faults and detect changes along faults.
Can Seismographs only detect earthquakes within 100 miles?
Seismographs can detect earthquakes from far beyond 100 miles if sensitive enough. Sometimes many instruments at great distances are used to calculate the severity of the quake.
What is the shawdow zone?
An area of Earth's surface where seismographs cannot detect an earthquake after waves has passed.
How is an earthquake located?
Seismographs placed around the planet detect the vibrations and calculate the epicenter using triangulation.
Is there a device to detect low frequency infra sound waves?
The most common such devices are the seismographs and Hydraphones.
How is an earthquake epicentre located?
Seismographs placed around the planet detect the vibrations and calculate the epicenter using triangulation.
What are three ways in which geologists use seismographs data?
They map faults, detect changes along faults, and develop a method of predicting earthquakes
How do you spell seismographs?
seismographs
What is used to detect hidden faults?
Geologists can use seismographs to detect hidden faults. When seismic waves encounter a fault, they are reflected off of the fault. Geologists can use this information to chart the location of a depth of a hidden fault.
