A drone mission has alarmed scientists monitoring the erupting Hawaii volcano, which has become one of the world's most dangerous and volatile sites.
Kilauea has shocked the world with streams of lava swallowing houses and giant fissures opening up across Hawaii.
The latest aerial drone footage of the volcano has revealed dramatic changes within the volcano spotted at one of Kilauea's main craters
There are new alarming cracks and fault seen in a collapsed crater, some of which are spewing with intense steam.
Scientists are concerned that an "expanding collapsed crater" and the debris blocking the vent could trigger a massive explosion.
