The Christian humanitarian organization, World Vision, began distributing "hundreds of blankets and some water containers to Santiago's earthquake survivors over the weekend," according to a press statement released by the charity.
"We are extremely concerned about the emotional impact of so many aftershocks on children. Not only the physical needs, but the psychosocial needs of children in the quake zone will be a priority once the full extent of the needs are known and we can begin delivering much-needed supplies," said Tatiana Benavides, World Vision's national director in Chile.
Paul Simons, the U.S. ambassador to Chile, told "Good Morning America" Sunday that all American employees at the U.S. Embassy have been located.
"We have no reports of any [American] fatalities or serious injuries," Simons said.
However, he added that that, as of this morning, the embassy had no reports from Concepcion.
The earthquake, which hit just after 3 a.m. local time Saturday, was stronger but much deeper than last month's Haitian earthquake, likely making the number of casualties far fewer than those in the Caribbean nation.
The Chile earthquake struck 22 miles below the surface in the Bio Bio region of the country, while the Haiti earthquake struck only 6 miles below the surface, according to scientists with the U.S. Geological Survey.
The three-minute quake struck less than 100 miles north of Concepcion but caused damage as far away as the capital, Santiago, nearly 200 miles away.
In the hours after Chile's quake, coastal cities from Japan to Australia were placed on alert for a tsunami. Most areas were spared widespread destruction from the waves, though at least five deaths and 11 people missing were reported on Robinson Crusoe Island off Chile, according to the AP.
Ronald Scott, an American who was staying at a hostel in Santiago when the earthquake hit, told ABC News that while he was terrified, the damage he witnessed was far less extensive than what he saw reported from Haiti.
"It was very scary," Scott said. "The first thing I did was jump underneath the first table I could find and even that was about to collapse on me.
"Everything just started jumping up and down, the lights went out and everything sounded like a railroad train," he said. "The buildings were shaking, but they're still standing because of the construction."
The buildings in Chile are constructed specifically to withstand earthquakes, and the country is no stranger to disaster from an unexpected quake.
"Since 1973 they've had 13 earthquakes over 7.7 magnitude," said Paul Earle, a seismologist from the U.S. Geological Survey.
Chile has the record for the world's strongest recorded earthquake -- a 9.5 magnitude quake that struck in 1960.
That earthquake sent a tsunami to Hawaii that killed 61 people and destroyed 500 homes. Tsunami waves triggered by an earthquake can travel at the speed of a jet before slamming into a distant coast as unusually high waves.
This time, Hawaiian officials cleared beaches and sounded alarms for hours before the expected arrival of the tsunami.
But scientists with the Pacific Tsunami Center said the islands "dodged a bullet." Hawaii's tsunami waves, which hit around 1 p.m. Hawaii time, were relatively mild and did not cause any damage.
