Hawaii lava flow destroys first home

A stream of lava that has been creeping towards a Hawaii town for months has now destroyed a house.
The people living in the house in Pahoa, Big Island, had already left.
The lava from Kilauea volcano entered the town two weeks ago and has smothered a cemetery and two sheds.
Can you stop lava?
The temperature of lava is 1000 degrees Celsius - ten times hotter than boiling water from a kettle.
It's so hot that it consumes everything it touches.
The United States once tried to stop a lava flow in Hawaii by bombing it - but the bomb crater left behind just refilled with lava.
In Iceland, crews used billions of gallons of cold water to cool down a lava flow.
"You have to be in a wealthy country with a lot at stake to even consider it," said Dr Shannon Nawotniak.
