The fear now is of a tsunami. Hawaii is on the alert.
For additional geography on the earthquake check out the P-Wave Map. For instance, it took nine minutes and four seconds for the force of the Peruvian earthquake to reach Washington D.C. Also note there was a force on the antipode in Indochina.
For general background: earthquakes are measured on a logarithmic scale known as the Richter Scale. For example, an 8.0 would cause ten times more shaking and release thirty times more energy as would a 7.0. A 7.0 would cause one hundred times more shaking and release nine hundred times more energy.

As I understand the magnitude as a Californian, there is a 30-fold increase in energy released per full magnitude number so the difference between a 5.0 and 7.0 would be 900 times greater.
