IQUIQUE, Chile (AP) — A powerful 7.6-magnitude aftershock hit Chile's far-northern coast late Wednesday night, shaking the same area where a magnitude-8.2 earthquake hit just a day before causing some damage and six deaths.
Chile's Emergency Office and navy issued a tsunami alert and ordered a precautionary evacuation of low-lying areas on the northern coast, meaning many people could be spending another sleepless night away from their homes.
The aftershock caused buildings to shake and people to run out into the streets in the port of Iquique, which was one of the cities that saw some damage from Tuesday night's big quake. But there were no immediate reports of new damage or injuries from the latest tremor, which was one of dozens that have followed the 8.2 quake.
"I was evacuated like all citizens. One can see that the people are prepared," tweeted President Michelle Bachelet, who was in the nearby city of Arica to assess the damage.
The aftershock was centered 12 miles (19 kilometers) south of Iquique at a depth of 25 miles (40 kilometers), the U.S Geological Survey said. The USGS initially reported the tremor's magnitude at 7.8, but downgraded it to 7.6.
It was felt across the border in southern Peru, where people in the cities of Tacna and Arequipa reportedly fled buildings in fear.
On Tuesday, authorities reported just six deaths from the initial quake, but said it was possible others could have been killed in older structures made of adobe in remote communities that weren't immediately accessible.
About 2,500 homes were damaged in Alto Hospicio, a poor neighborhood in the hills above Iquique, a city of nearly 200,000 people whose coastal residents joined a mandatory evacuation ahead of a tsunami that rose to only 8 feet (2.5 meters). Iquique's fishermen poked through the aftermath: sunken and damaged boats that could cost millions of dollars to repair and replace.
Still, as President Michelle Bachelet deployed hundreds of anti-riot police and soldiers to prevent looting and round up escaped prisoners, it was clear that the loss of life and property could have been much worse.
The mandatory evacuation lasted for 10 hours in Iquique and Arica, the cities closest to the epicenter, and kept 900,000 people out of their homes along Chile's 2,500-mile (4,000 kilometer) coastline. The order to leave was spread through cellphone text messages and Twitter, and reinforced by blaring sirens in neighborhoods where people regularly practice earthquake drills.
But the system has its shortcomings: the government has yet to install tsunami warning sirens in parts of Arica, leaving authorities to shout orders by megaphone. And fewer than 15 percent of Chileans have downloaded the smartphone application that can alert them to evacuation orders.
Chile is one of the world's most seismic countries and is particularly prone to tsunamis, because of the way the Nazca tectonic plate plunges beneath the South American plate, pushing the towering Andes cordillera ever higher.

A powerful earthquake with a preliminary magnitude of 8.2 struck off the coast of Chile tonight, strong enough to be felt nearly 300 miles away in the Bolivian capital, and triggering a small tsunami.
Five people are confirmed dead - four men and one woman, Chilean Interior Minister Rodrigo Penailillo said. The victims died from either cardiac arrest or falling debris.
The quake, which was centered 61 miles west-northwest of Iquique, and was 6.21 miles deep, was initially measured at 8.0, but was later upgraded, the U.S. Geological Survey said.
The Pacific Tsunami Warning Center said a six-foot tsunami hit Pisagua, Chile, at 8:04 p.m. ET. There was some damage reported on roads linking northern towns between Iquique and Alto Auspicio.
A tsunami warning for countries in the area - including Peru, Ecuador, Colombia and Panama - was canceled.
An advisory remains in effect for Hawaii, but the waves aren't expected to cause much damage, Gerard Fryer, a geophysicist at the Pacific Tsunami Warning Center, told ABC News.
"The waves will not be big enough to cause any flooding, so nobody needs to evacuate. But we just want to clear the beaches. And fortunately, since it's 3:30 in the morning, that's really no hardship," Fryer said.
“The biggest worry is the currents. If anyone is in the water, you know fishing or something like that, they could get banged up or swept out to sea or something.”
The northern part of Chile is being declared a disaster zone and armed forces are on their way to the area, President Michelle Bachelet said at an overnight press conference. The presidents of Peru and Argentina have called, lending support if needed, Bachelet said.
The earthquake was so strong that the shaking it caused in La Paz, Bolivia, 290 miles from the epicenter, was the equivalent of a 4.5-magnitude tremor, authorities there said. The quake triggered at least eight strong aftershocks in the first few hours, including a 6.2 tremor.
In Chile, evacuation orders were issued for the cities of Arica, Iquique and Antofagasta. All cities were along a low coast and each evacuation involved a significant climb to higher land further inland.
Salvador Urrutia, the mayor of Arica, said there were minor injuries in the city but no deaths reported. Some homes were damaged, but the modern structures and taller buildings were not damaged.
He said the city was without power and had no cellphone service.
Despite the fear caused by the evacuation order, which was not limited to the coast, he said people remained calm.
