The fires burned thousands of homes and commercial buildings to the ground.
The deadly wildfires that erupted on the Hawaiian island of Maui on Aug. 8 have become the deadliest natural disaster in state history, officials said.
The blazes spread rapidly due to very dry conditions stemming from a drought combined with powerful winds. Much of the historic town of Lahaina has been "destroyed," officials said, and the inferno has burned thousands of residential and commercial buildings to the ground.
On Thursday, "Good Morning America" and ABC News organized efforts to help viewers get involved in relief efforts for survivors of the Maui fires.

Over 100 people have died from the devastating wildfires on Maui. Officials have warned that the death toll is expected to rise as they work to contain the active blazes and assess the damage.

South Korea has donated $2 million to Hawaii in support of Maui fire relief, officials said.
The Hawaii Community Foundation said the donation will help support the short-, mid- and long-term recovery of Lahaina, including addressing medical needs and helping families displaced by the fires.
The first fire reported on Maui may have been caused by damaged power lines, according to Bob Marshall, CEO of the power monitoring company Whisker Labs.
On Aug. 7 at 10:47 p.m., a security camera at the Maui Bird Conservation Center captured a bright flash in the woods that, according to Jennifer Pribble, a senior research coordinator at the conservation center, may have been a tree falling on a power line. After that, the power went out, she said.
The fire was reported shortly after midnight, according to Maui County officials.
According to Marshall, that bright flash seen on video was likely an explosion from a power line fault, meaning the power line came into contact with something like a tree or vegetation.
Marshall told ABC News that its sensors at Maui homes recorded a "very sharp drop in electrical voltage" at precisely the same time the flash was seen on the security video.
"The grid was incredibly stressed Monday night and throughout the day on Tuesday," Marshall said. “It was trying to deal with the winds that it was encountering. and what our network clearly documents is that there were 122 faults that occurred throughout that time period, any one of which could have ignited a fire."

Maui is facing a "very long and hard recovery," FEMA Administrator Deanne Criswell said at Wednesday's White House briefing.
Criswell called the response a "very active and dynamic situation" with FEMA search and rescue teams continuing to work closely with state officials to look for those who are missing.
She said 30 specialists from the Department of Health and Human Services' mortuary teams are in Maui and will soon be joined by a team from the Department of Defense to help identify loved ones.
At least 40 canine search teams are also on the island, "in addition to hundreds of search and rescue personnel, with more on the way," she said. "We're working carefully to search the affected areas thoroughly and compassionately while respecting all of the cultural sensitivities."
Criswell spoke to how difficult and lengthy this search operation will be for the canines to endure the heat and maneuver through the fire debris.
"They have to deal with issues with their paws, walking through glass and debris. And in these conditions, the dogs require frequent rest, which is why we are sending in additional dogs to augment the operation," she said.
FEMA has given $2.3 million in assistance to families. She said there's resources to pay for home repairs, cars and appliances, but only 1,300 households are registered with FEMA so far.
Before the briefing, Criswell updated President Joe Biden on the recovery efforts. Criswell said Biden spoke with Hawaii's governor again on Wednesday and approved the state's request for 100% reimbursement for the emergency work that's being done "for a period of 30 days within the first 120 days at the governor's choosing."
Criswell said that when Biden visits Maui on Monday, "he's going to be able to bring hope."
"He's going to speak with the governor and the state’s first lady, and talk to survivors and hear their stories," Criswell said. "And it’s that level of hope that I think is going to really be a positive impact for this community."

Katie Shannon of the Maui Humane Society estimates that 3,000 pets are missing from wildfire-ravaged Lahaina.
So far, the Maui Humane Society has received 52 injured animals, including some suffering from smoke inhalation and some with burns, Shannon told ABC News.
"We have also seen severe burns -- cats that look, I don't think that their owner may even know that it is their cat because they look so burnt. Their ears are burnt, their faces are burnt. It's just incredibly severe," Shannon said.
The Maui Humane Society is not only sending food and supplies to the hardest-hit areas, but is also trying to reunite owners with their pets. A dog named Roman was separated from his pet sitter during the fire when the sitter jumped into the ocean and Roman refused to follow. Roman, who was missing for a couple days, was found by a good Samaritan, taken to the humane society and, thanks to his microchip, was reunited with his owners.
"That is our goal -- to reunite every pet and owner, and also to provide the lifesaving care that these pets need," Shannon said.
The Maui Humane Society is sending many of the animals it had on site before the fires to the mainland to make room for the animals coming in from the Lahaina area.
