Following the killer quake on the island of Lombok on Sunday - which has so far claimed at least 142 lives and injured more than 200 - users took to the social network to share their messages of condolence and support.
"The quake was felt strongly".
More than 300,00 people have been displaced, with national disaster agency spokesman Sutopo Purwo Nugroho telling AEC News Today "there has been been tremors shaking the ground every day; walls between properties are felling (sic) down; there is no electricity for almost all of the north of Lombok".
"We were stuck in traffic while delivering aid, suddenly it felt like our auto was hit from behind, it was so strong", witness Sri Laksmi told AFP.
Witnesses said people ran into the roads in a panic and some buildings collapsed.
Widodo visited the island after a 6.4 magnitude quake on July 29 killed 17 people and injured dozens more.
The head of a Red Cross assessment team on the Indonesian island of Lombok has described Sunday's magnitude 7 natural disaster as "exceptionally destructive", warning that it may still take days for the full impact to emerge.
"We still need long-term aid, even though we have already received help from various (regional) governments", national disaster agency spokesman Sutopo Purwo Nugroho said.
Lombok is a roughly 4,500 sq km (1,700 sq miles) island east of the slightly larger island of Bali. Some villages have collapsed entirely.
In total, an estimated 20,000 people have been displaced by the massive quake.
Thousands of tourists have been evacuated from Lombok and the Gili Islands. An interagency meeting will be held Thursday to compare information, Nugroho said.
Many people made homeless by the quake were sleeping in makeshift shelters in rice fields or on the roadside, according to Silverius Tasman, from Yayasan Sayangi Tunas Cilik, a partner of Save the Children in Indonesia.
"Many patients here have broken bones and we handle it as much as possible because the hospital is damaged, impossible to do surgery and treat patients with severe injuries", she said. Crews using heavy equipment to search a collapsed mosque in northern Lombok found three bodies but also managed to pull one man alive from the twisted wreckage. Doctors at another Lombok hospital had to amputate it.
Some evacuees have complained of being ignored or experiencing long delays for supplies to arrive at shelters. He also said that search and rescue operations were ongoing but things weren't as smooth and they would like as the aftershocks added to the woes.
Aid reached numerous survivors, but there was still a lack of food, water and tents in areas hard to access.
