Authorities said there were power outages in some areas and many fallen trees and branches, but it was too early to assess the extent of the damage with Cyclone Judy still raging.Â
They said there were no initial reports of major destruction or deaths.
Some people had moved to evacuation sites as heavy rainfall flooded their homes.
Others were barricading themselves inside as authorities issued a red alert in the capital, Port Vila, and some other regions - meaning people shouldn't leave their homes unless absolutely necessary.
The cyclone forced businesses and schools to close, and airlines to cancel flights.
Brenda Williams, spokeswoman for Vanuatu's National Disaster Management Office, said Cyclone Judy was packing destructive winds of about 150 kilometres per hour with gusts of up to 200km/h.
Williams said the calmer eye of the tropical cyclone had passed over the capital on Wednesday morning and they were starting to experience strong winds again as the tail moved through.
She said the centre and southern islands were in line to be hit and they were still waiting on damage reports from many places.
Shadrack Welegtabit, a political adviser to the climate change minister, said people had been warned of the impending cyclone earlier in the week and had been preparing by stocking up on fresh drinking water and food, and by strengthening the exteriors of their homes.
"It's too early to assess the damage; we're still in the middle of it," he said. "The other half is coming soon."
Located east of Australia and north of New Zealand, Vanuatu is home to about 300,000 people.
