"(It's a) bit of luck I was there (Pentecost). Luckily I wasn't on Tanna which was the worst of all places that were affected."
Tanna in the south was one of the hardest hit and the cyclone's 270km/h winds pummeled lush tropical forests on the island into a brown jumble of broken trunks and strewn branches. Five of the island's 30,000 residents died in the disaster.
Mr Gearing said he helped clear debris on Pentecost but was unsure what work was left for him after the cyclone.
Communication had always been a problem on Pentecost, he said.
"I wasn't really in any urgent need. I realised people must have been concerned but there was no contact, not even radio telephone on the island.
"Even before Pam, communication hasn't been great," Mr Gearing said.
He said there was a big relief programme being run in Port Vila and he may be asked to help. If not, he is likely to head back home.
Ms Dykzeul said she received a message from him yesterday after being concerned he had not been in contact since the cyclone hit.
A large coalition of national and international humanitarian organisations are co-ordinating to send aid to Vanuatu, where 3,300 people are sheltered in 48 evacuation centres.
They are already finding it difficult to communicate and travel between Vanuatu's 82 separate islands.
