An early-morning view of an open lava channel at Kilauea volcano in Hawaii, seen during a helicopter overflight of the Lower East Rift Zone on Monday, in an image obtained on Tuesday from the United States Geological Survey (USGS). The latest video footage from USGS shows that the eruption is showing no signs of letting up and has destroyed more than 600 homes so far, according to the Hawaii Civil Defence Agency. The eruption began on May 3 and the lava now covers more than 4 per cent of the Big Island, Hawaii's largest. According to London's Express online, Kilauea has now spewed more than 25 million cubic metres of lava, enough to fill 100,000 Olympic-size swimming pools while filling a new one every 25 seconds. The lava now covers more than 24,000ha of the Big Island, which is still growing because of the lava flow.
