IQUIQUE, Chile — Coastal residents of Chile’s far-north spent a second sleepless night outside their homes early today after a major aftershock rattled an area hit a day earlier by a magnitude-8.2 earthquake that caused some damage and six deaths. No new major damage or casualties were reported.

After the 7.6-magnitude aftershock struck just before midnight Wednesday, Chile’s Emergency Office and navy issued a tsunami alert and ordered a precautionary evacuation of low-lying areas for the country’s whole 2,500-mile Pacific coastline.

Among those moved inland was President Michelle Bachelet, who was in the city of Arica assessing damage in the north from Tuesday night’s powerful quake.

“I was evacuated like all citizens. One can see that the people are prepared,” she tweeted early today.

Chile’s evacuation order was lifted around 2 a.m. today. The whole coast also was evacuated for several hours after Tuesday’s quake, and for the night in the north, although the tsunami proved small.
