Thousands of shaken Chileans have spent a second night in the streets and makeshift shelters following a 7.6-magnitude earthquake that struck 24 hours after an even stronger tremor killed six.
President Michelle Bachelet, who was assessing damage from Tuesday's massive 8.2 jolt, was among those forced to flee late on Wednesday as the latest temblor sowed terror among already exhausted and nervous residents.
The new quake struck in the Pacific Ocean at 11.43pm local time, 19km south of the northern coastal city of Iquique, the US Geological Survey said.
There were no reports of fatalities or major damage and authorities lifted a tsunami alert after two hours.
Families from the community near Iquique spent the night in tents put up on a soccer pitch, while others huddled around bonfires as temperatures dropped to a chilly eight to 10 degrees Celsius.

"It's the second night we're sleeping here, there's no way we can go home," she said.
"We have not been helped."
Tuesday's tremor and many subsequent aftershocks were felt as far inland as landlocked Bolivia and sparked evacuation warnings up the Pacific coast of South America and into Central America.
