€903,000 has been so far raised for the Creeslough Community Support Fund.
It was started earlier this week and is managed by the Irish Red Cross, while donations can be given at post offices nationally as well as Applegreen outlets.
The money will be used to support the local community in Creeslough.
Earlier, this week the Government announced it's opening its Humanitarian Assistance Fund to the families of those killed in county Donegal.
Funerals are continuing in Donegal today for the victims of the tragedy last Friday where 10 people lost their lives.
Donations to the Irish Red Cross fund can be made here.
Charlie Lamson in the Irish Red Cross said “the Irish public and the business world here have been just incredible with their thoughtfulness for the Creeslough community.
"At this stage our Irish Red Cross Donegal area volunteers are in touch with people in the Creeslough locality and they are in the process of identifying a process for the funding distribution which is appropriate and informed by the local community.”
A separate Go Fund Me account has also raised more than €400,000 for the victim's families and the community.
