According to Gutenberg-richter law, energy E (in gigajoules) radiated as seismic waves from the earthquake of Richter magnitude M can be evaluated by equation:
log(E) = -4.2 + 1.5M
Answer the following:
a) Write E as the function of M.
b) How much energy (in gigajoules) would the earthquake of magnitude 3.9 generate?
c) How much energy (in gigajoules) would the earthquake of magnitude 5.1 generate?
d) How much more devestating is the earthquake of magnitude 5.1 compared to earthquake of magnitude 3.9?
