###### Question details

(Using MATLAB) The amount of energy *E* (in joules) that
is released by an earthquake is given by:

E=1.74×10^19×10^(1.44M)

where *M* is the magnitude of the earthquake on the
Richter scale.

- (
*a*) Determine the energy that was released from the Anchorage earthquake (1964, Alaska, USA), magnitude 9.2. - (
*b*) The energy released in Lisbon earthquake (Portugal) in 1755 was onehalf the energy released in the Anchorage earthquake. Determine the magnitude of the earthquake in Lisbon on the Richter scale.
