YOU'VE got hot mail . . . Vanuatu unveils today what is believed to be the world's first volcanic postbox, with the help of Kiwi ingenuity.
The postbox near the fiery rim of Mt Yasur on the island of Tanna, is the Pacific nation's second "xtreme" facility.
An underwater post office was opened in a marine sanctuary off Hideaway Island, on the outskirts of Vanuatu's capital Port Vila in 2003.
Both come courtesy of New Zealand Post, contracted to run Vanuatu's postal service, with mail from each collected and postmarked.
Yasur, one of Vanuatu's most popular tourist attractions, erupts up to 20 times every hour, its three vents throwing lava showers hundreds of metres into the air. "It's got to be the most exciting place on the planet to send a postcard from" chief executive Gary Ryan said.
Commemorative stamps, postcards and first-day covers are being issued to celebrate the launch.
