 A megathrust quake can shake the entire earth, but causes stronger movement and strain on the entire associated oceanic plate, beyond the few hundred kilometer rupture zone.Though too far to be an aftershock, a 6.0 quake on a thin protruding wedge of the Nazca Plate (Iquique quake shoved this plate) was reported off Panama within 12 hours of the main shock.Under advice from the Pacific Tsunami Warning Center, tsunami warnings were issued for the Latin American Pacific coastlines of Chile, Peru, and Ecuador shortly after the earthquake occurred.
