The O'ahu-based Pacific Tsunami Warning Center responded to yesterday's earthquake with a tsunami warning for the coasts of Peru, Chile, Ecuador, Colombia, Costa Rica and Panama. A tsunami watch was issued for the rest of Central America and Mexico, and an advisory for Hawai'i.

The center canceled all the alerts after about two hours, but it said the quake had caused an estimated 10-inch tsunami near the epicenter.

"It wasn't big enough to be destructive," said Stuart Weinstein, the center's assistant director.
