What do scientists use to predict earthquakes?

Answer 1

Scientists do [or do not!] predict earthquakes in the following ways:

1. Reference to oral traditions, official papers, and eyewitness accounts regarding previous earthquake activity;

2. Physical evidence, such as:

Soil upheavals on the earth's surface;

Presence of volcanoes;

Location in the area of earthquake fault lines, such as the San Andreas fault line of Southern California;

Increases in radon gas levels in wells and basements;

Ground water;

Animal behavior modification, such as suddenly homelessness of burrowing animals or suddenly agitated flight and communication patterns by birds;

3. Indications of underground activity, such as:

Disruption of light beam transmission from one side of a fault line to another;

Magnetic field modifications;

Movements of the earth's soil and crust;

Vibrations or shock waves.

Answer 2

Scientists use seismometers to detect and record seismic waves, GPS data to monitor ground movement, and computer models to analyze fault behavior and predict where future earthquakes might occur. They also consider historical patterns of seismic activity in a given region to assess earthquake risk.

Answer 3

The following are five instruments that are used to predict earthquakes:

1. Creepmeters, to warn of movement of the earth's soil;

2. Global positioning systems, to warn of movement of the earth's crust;

3. Laser light, to warn of disrupted light beam transmission from one side of a fault line to the other;

4. Magnetometer, to warn of changed magnetic field activity;

5. Strainmeter, through the coordinated use of the seismometer and the seismograph, to warn of underground vibrations or shock waves.

Answer 4

Instruments that are used to predict earthquakes include the following:

1. Creepmeters, to warn of movement of the earth's soil;

2. Global positioning systems, to warn of movement of the earth's crust;

3. Laser light, to warn of disrupted light beam transmission from one side of a fault line to another;

4. Magnetometer, to warn of magnetic field changes;

5. Strainmeters, through the coordinated use of the seismometer and the seismograph, to warn of underground vibrations or shock waves.

Answer 5

Predicting earthquakes is giving the time, location and magnitude of a future earthquake within quick limits. Seismologists use precursors, animal behavior, radon emissions, and electro-magnetic variations to predict earthquakes.

Answer 6

The five types of instruments and machines that seismologists may use to predict [or not predict!] earthquakes are the following:

1. Creepmeters, to warn of movement of the earth's soil;

2. Global positioning systems, to warn of movement of the earth's crust;

3. Laser light, to warn of disrupted light beam transmission from one side of a fault line to another;

4. Magnetometer, to warn of changed magnetic field activity;

5. Strainmeters, through the coordinated use of the seismograph and the seismometer, to warn of below ground vibrations.
