Magnitude is a measure of the amplitude, or strength, of the seismic waves produced by the rocks releasing energy by moving below the surface of the earth.
Depth simply refers to how far down below the earth's surface the earthquakes originates. The deeper the depth of the focus (where the earthquake begins) the farther the energy released has to travel to reach the earth's surface. Because the seismic waves travel farther through the crust, they lose amplitude or energy along the way, becoming weaker.
So, if you have two earthquakes that release the same amount of energy, the deeper one will have a lower magnitude at the earth's surface.
A hard question because it asks to compare apples and Oranges, so to speak. plate boundaries are expressed as fault zone traces at the Earths surface, for example, the San Andeas fault. as strain is built up along the fault because of plate motion, eventually an earthquake uccurs because the plates will slip past each other. The greater thee slip the bigger the earthquake. However, earthquake strain depends on depth as a lot of compressive energy has to be stored to be released as an earthquake. Generally this occurs at depths greater than about 5 km. Really great earthquakes occur along subducting plate boundaries at depths from about 15 to 40 km, but rarely much deeper because below about 40 km the rocks become plastic and tend to flow rather than break.
The deeper an earthquake is, the less effect it has in the surface of the Earth in the way of buildings destroyed etc.
The magnitude is not affected by the depth. Both factors together determine the level of destruction caused by an earthquake.
We don't know how to predict earthquakes. Given California's history and that it is on a fairly active fault line we can say that it will certainly continue to have earthquakes and at some point there will be a big one. But as to when, no one knows.
I have been doing some maths and found that in the average year, you'd get about 3,610,364(3 million, 6hundred and 10 thousand, 3hundred and sixty four) earthquakes in a year. Ofcourse these are all around the globe. About 2 million of these are bellow 2 on the Richter scale.
volcanic eruptions and earthquakes
The Mercalli scale, which measures the visible effects; and the Richter scale, which measures the energy given off by the earthquake, are the two most common ways of measuring the size of an earthquake.
Some geologists specialize as geophysicists, who study the physical properties and processes of the Earth. This field includes seismology, or the study of earthquakes. A person who studies earthquakes is called a seismologist.
The answer would be false. What is clearly unpredictable is the magnitude of any given earthquake.
Earthquakes aren't given names, but they are given magnitudes, if that's helpful. The magnitude for the earthquake that caused the Hati disaster was 7.0.
Divergence is a vector operator that measures the magnitude of a vector fields source or sink at a given point.

The moment magnitude scale, the Richter scale (which can only be used for low and moderate magnitude earthquakes less than 6.9) and the modified mercalli intensity scale are used to measure earthquakes.
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
velocity
The term for the instrument that measures the seismic waves of earthquakes along faults or tectonic plates is known as a seismograph. These machines measure the force given off by the trembling of the ground due to the force of an earthquake. The strength is measured as magnitude on the "Richter scale" which is a logarithmic quantity. For example, the motion generated by a quake of magnitude 5 on the Richter scale is 10 times as large as that generated by a quake of magnitude 4.

Seismology.
height and depth of a tree is equal... but height and depth of a node is not equal because... the height is calculated by traversing from leaf to the given node depth is calculated from traversal from root to the given node.....
