[00:00.00]This is a view of the Pacific as seen from space-
[00:04.59]a vast expanse of water that covers almost a third of the Earth’s surface.
[00:09.93]Today, only 1% of this vast ocean is land,
[00:14.86] and much of it owes its existence to the explosive powers of volcanoes like Kavachi.
[00:21.20]1,500 miles north of the equator,
[00:25.17] perhaps the most famous group of volcanic islands in the world -
[00:29.47]Hawaii, still one of the most volcanically active areas on Earth.
[00:35.41]And this is Kilauea. Like all volcanoes, it’s plumbed into the very heart of the Earth - home to a lot of hot, angry rock.
[00:45.29]Rising from 60 mile below the ocean’s floor,
[00:49.14]this lava has flowed nonstop for 25 years.
[00:53.61]On the lower slopes, the lava travels at less than 100 meters an hour,
[00:58.46]betraying little of its awesome power.
[01:01.16]Nothing can survive this smouldering blanket.
[01:04.88]As the crust cools, it is lifted by the lava still flowing beneath it.
[01:10.78]The advance is relentless and unpredictable, changing direction without notice.
[01:17.34]Roads here are regularly swept away and some are now buried under 35 meters of rock.
[01:26.30]In the last 20 years, more than 200 homes have been destroyed by Kilauea’s flow.
[01:33.28]And it doesn’t stop here.
