Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.

10 What country had the largest recorded earthquake?
Indonesia has the most earthquakes because it's in a very active seismic zone, but Indonesia is a very large country. Japan experiences more earthquakes per year per square kilometer than any other country.
What does a Richter scale measure on an earthquake?
RICHTER SCALEThe Richter scale (known as the local magnitude scale to seismologists) was originally developed to measure small to moderate magnitude earthquakes in southern California by Charles Richter and Beno Gutenberg. The numerical levels indicate the energy released by a particular quake. The numerical value is obtained from the logarithm of the maximum amplitude of seismic waves as recorded on a seismometer. This value is then scaled to account for the distance from the epicentre of the earthquake to the seismometer so as to allow the value to be correlated with the local magnitude readings from other seismometers in differing locations (as seismic waves lose their energy as they propagate through the earth so if this correction was not made, then different seismometer stations at different distances would give differing Richter magnitudes for the same earthquake). The Richter magnitude measurement produced by this methodology in theory has no limit and may be positive or negative.As stated above, the Richter scale itself is a logarithmic mathematical formula which is calibrated so that a ten fold increase in amplitude relates to a single whole number increase on the scale (e.g. an earthquake with a Richter magnitude of 5 has seismic waves with a maximum amplitude 10 times larger than those for a magnitude 4). It has a number of practical limitations, in that it is poor at recording earthquakes with magnitudes greater than 7 and at distances greater than 650 km from a seismometer.The equation for calculating the Richter magnitude (MR) is shown below:MR = (Log10A) - (Log10A0)WhereA = maximum zero to peak amplitude of seismic wave (mm) recorded.A0 = Empirical function derived from the distance from seismometer station to earthquake epicentreLog10A0 From 0 to 200 km distance:Log10A0 = 0.15 - 1.6 log(distance in km)Between 200 and 600 km distance by:Log10A0 = 3.38 - 3.0 log(distance in km)Due to the limitations described above (distance and maximum size of measurable earthquake), it has since been replaced by the Moment Magnitude Scale in the measurement of large earthquakes - for information on this, please see the related question.the richter scale reads the magnitude of earthquake.
How do MEDCs prepare for earthquakes?
They build stronger buildings than LEDCs. They give buildings shock absorbers. They give hospitals bakc-up generators. However, they can still be damged very badly by earthquakes.
What happens when an earthquake takes place?
Earthquakes are caused by the slipping of rock under the crust. The waves still travel on the ground, as they would above water, but the waves would cause a tsumai to happen.
How do seismograms recorded during earthquakes help scientists learn about the composition on earth?
Seismograms recorded during earthquakes help scientists learn about the composition of the earth by measuring the seismic waves that travel through the different layers of the Earth. The characteristics of these waves, such as their speed and amplitude, can provide information about the density, elasticity, and temperature of the materials they pass through. By analyzing seismograms from different locations, scientists can map the structure and properties of the Earth's interior, including the boundaries between different layers and the presence of seismic discontinuities.
Earthquakes are detected by what barometer Richter scale seismograph global positioning system?
The energy released by earthquakes take the form of seismic waves which travel through the ground. These are detected by a seismograph. Based on the amplitude of the seismic waves measured by the seismograph the earthquakes strength can be calculated (to give a value on the Richter scale). Large earthquakes can cause permanent displacements / deformation at the Earth's surface whereby the change in position of an object can be detected using GPS.
How does monitoring seismic images help us to understand how the world is made up?
Seismic images give vital information about Earth's interior,help locate petroleum,detect nuclear tests,and predict earthquakes.
How have geologists learned about earth's structure?
they have used two methods direct and indirect. seismic waves are the forces produced when earthquakes occur.from rocks from deep inside earth they can give inferences about conditions deep inside earth. they also record the seismic waves and record how dast they travel through Earth this is an indirect method

What name do we give to the sections of the earth where no seismic waves can travel?
It's the focus

Scientist learn about the earth's interior by studying?
Scientist learn about the earth's interior by studying seismic waves. 'P' waves travel all the way through Earth's crust, mantle, outer and inner core and give scientists a glimpse of the interior.
Can you give me a sentence with the phrase Richter scale?
The May 2015 earthquake that hit Nepal registered 7.8 on the Richter scale.Two weeks later, a 7.3 Richter scale earthquake hit very close to Mount Everest.The Richter scale is a standardized method to measure and report the force of seismic waves that earthquakes produce.
Explain how seismic waves help scientists learn about earth interior?
Seismic waves bounce off things inside of the Earth, helping scientists figure out it's interior. An example is like if you taped a block in a box, put a marble inside of the box, and closed the lid. By tilting the box, the marble would roll and you'd get a pretty good idea where the block is located.
Give three examples of mechanical waves and identify the medium through which they travel?
There are only two types of mechanical waves: longitudinal waves, and transverse waves..In a longitudinal wave, the waves themselves oscillate, or vibrate, in the same direction as the wave travel. Longitudinal waves are also called compression waves. Sound and seismic P-waves are examples of mechanical longitudinal waves..In a transverse wave, the waves oscillate perpendicular to the direction of the wave travel. Ocean waves and seismic S-waves are examples of mechanical transverse waves..See the related links for further information about longitudinal and transverse waves.
