How do geologists use seismograph data to make maps of faults?

How do geologists use seismograph data to make maps of faults?

How do geologists use seismographic data to make maps of faults? Seismographs detect the reflected seismic waves and geologists use this data to map the length and depth of the fault. Why do geologists collect data on friction along the sides of faults? So they can try to predict the probability of a large earthquake.

How do scientists use seismographs to learn about earthquakes?

Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth’s surface caused by seismic waves. The term seismograph usually refers to the combined seismometer and recording device.

How do seismic waves act when they encounter a fault?

List 4 instruments that geologists use to monitor movements along faults. How do seismic waves behave when they encounter a fault? They learn the location of hidden faults.

How do geologists learn about how the blocks of rock along a fault move?

Geologists use fault-monitoring devices to study the types of movement that occur along faults. Friction is the force that opposes the motion of one surface as it moves across another surface. Where friction along a fault is low, the rocks on both sides of the fault slide by each other without much sticking.

In what form the seismograph gives the record of waves?

These are called seismic waves. This instrument record those waves. Seismographs are equipped with electromagnetic sensors that translate ground motions into electrical changes, which are processed and recorded by the instruments’ analogue or digital circuits.

How does a seismograph detect and record seismic waves quizlet?

How does a seismograph record seismic waves? Seismic waves cause a seismograph’s drum to vibrate. But the suspended weight with the pen attached moves very little. Therefore, the pen stays in place and the records the drums vibrations.
