In both cities, Bachelet visited the aid distribution centers for their respective regions.

Speaking on a false tsunami warning by the firemen in Concepcion on Wednesday following a powerful aftershock, which caused confusion among the public, Bachelet said the firemen had said it was a non-official alarm, but "at the end we should say that it is better an extra alarm than a missing one."

"However, we must be careful, because evacuating a city without reason is also costly for the people," Bachelet added.

Chilean authorities said the death toll from the magnitude-8.8 earthquake has risen over 800 and about 2 million others were affected.

Quake-caused damage to Chile is so far estimated at up to 30 billion U.S. dollars, or a fifth of the country's gross domestic product.

UN Secretary-General Ban Ki-moon will visit Chile on Friday to show his "solidarity" with the Chilean people, his spokesperson said.

Ban is expected to meet with Bachelet and President-elect Sebastian Pinera.

Chilean Foreign Minister Mariano Fernandez said a meeting will be held between representatives of international organizations and the Chilean government to discuss priorities of international aid.
