Lava from Hawaii volcano cascades into sea in vivid display

For the first time in three years, lava from a volcano on Hawaii's Big Island has crept down miles of mountainside and is dripping into the Pacific Ocean-where it's creating new land and a stunning show for visitors.

Thousands of people from around the world have swarmed Volcanoes National Park by land, sea and air to view the lava. They're also hearing and smelling it.

The billowy, bright-orange lava crackles and hisses, and reeks of sulfur and scorched earth, as it oozes across the rugged landscape and eventually off steep, seaside cliffs. When the hot rocks hit the water, they expel plumes of steam and gas - and sometimes explode, sending chunks of searing debris flying through the air.
