The danger from Wednesday's 8.8 magnitude earthquake appeared to be subsiding in most places, but Chile kept alerts at the highest level for most of its lengthy Pacific coast while New Zealand renewed a warning to avoid the water.

Chile has upgraded its tsunami warning to its highest level. The red alert covers most of its 6,400-kilometer (4,000-mile) Pacific coastline, from Arica and Parinacota near its northern border to Magallanes in the far south. The Education Ministry also canceled classes along much of the coast.
