So if we know that an earthquake has happened in California, then scientist know that the crust under California is unstable, therefore making earthquakes more likely to happen there. Earthquakes can happen anywhere, but the tend to happen repeatedly in certain spots

As a basis of comparison to a known standard. This helps in better understanding the nature of earthquakes over a long period of time.
geologic maps
Maps are useful to us in different ways such as providing information of locations or ground quality such as fault structures or existing drainage.
Well, look in the Discovery Works Sience Book!
Two separate systems used to measure earthquakes are important for accuracy. More than one system to measure gives scientists an accurate measurement of an earthquakes strength.
Yes they help get scientist together with scientists as well as showing the public at large what technology may be available to them in their lives and businesses.

Why are data tables useful to scientists? It is Important for scientist to use data because data is what they use to write their observation
9 constellations are useful to man, they are useful in showing directions with reference to Pole star.
that is what the scientists use to experiment
It gives them an example of what they are working with
Yes. Landmarks or skymarks are useful for reference points for locations.
