CONCEPCION, Chile - A strong aftershock to Chile's deadly earthquake provoked a brief panic in the city of Concepcion, but no tsunami warning was issued and no injuries or damage have been reported.
Some residents started running for high ground when they felt the aftershock to Saturday's earthquake, which itself produced a deadly tsunami.
The U.S. Geological Survey says Wednesday's temblor had preliminary magnitude of 5.9. The agency initially reported two aftershocks occurred.
Fire officials used loudspeakers to assure residents that no tsunami was imminent. Concepcion was badly damaged by Saturday's magnitude-8.8 quake.
