gimme some info, definition of earthquakes magnitude?? like measured in rector scale??

dan815 · Answer

4.4*10^2 what units

dan815 · Answer

okay  SO

dan815 · Answer

300 km way we felt a wave with a max amplitude of 4.4*10^2 um

dan815 · Answer

We need to see the avg rate of decay of a wave on the surface of the earth.

dan815 · Answer

e^alphax*sin x
where alpha is a complex number is the general form of a decaying wave, need some extra information about the earth to figure out this rate of decay.
