Gardai have started 'door-to-door' enquiries in the village of Creeslough as part of their investigation into the cause of the horrific Co Donegal explosion.
Ten people were killed when the explosion ripped through the Applegreen Service Station just after 3.15pm on October 9th last.
A huge investigation has now commenced into the cause of the blast.

A Garda spokesperson has now warned villagers that they have launched local enquiries.
As part of that investigation locals will be asked if they noticed anything unusual in the moments before the explosion.
A possible gas leak is one theory which is being considered by investigating officers.
Gardai said they did not want to alarm any residents.
The Garda spokesperson said "We wish to make members of the Creeslough community aware that Gardaí are in the area at present conducting routine door to door enquiries and that this will also be the case over the coming weeks.
"We certainly do not wish to cause any alarm or upset by calling to houses in which residents are unaware of our intention to do so.
"Please inform neighbours and friends of our intention to call by, especially those who are not on social media. Thank you."
Garda Superintendent Liam Geraghty said previously that the more technical details of the investigation have now commenced.
"The Garda investigation has now commenced following the completion of the search and rescue,” he said.
“The investigation will take a period of time and the Technical Bureau will be on the scene in the coming days and agencies and other sections within An Garda Siochana.
"That investigation will take a period of time and the investigation is there to investigate the cause.
"There will be technical investigations, although they may not be the same level of activity that we saw during the search and rescue investigation but there will be continuing, as the experts determine what we need to do."
Meanwhile, investigators are still picking their way through a huge mound of debris removed from the site of the blast and compiled at a site on the outskirts of the village.
The debris was taken there by dozens of local contractors from the site of the blast in the hours and days after the explosion.
As well as masonry and furniture from apartments destroyed in the blast, some personal items including clothing and footwear can be seen in the rubble.
Gardai remain at the scene of the debris as it will form a part of the overall investigation into the possible cause of the blast.
