The Kilauea volcano on Hawaii's Big Island is continuing to blow off toxic steam and release lava, but scientists now say there are signs it could be about to explode in a once-in-a-century eruption.
Geologists are warning of a possible explosion which would be the largest explosion in nearly 120 years, CBS News reports.

It could hurl boulders the size of a refrigerator several kilometres away from the crater.
As lava levels drain lower inside the crater, the danger of an eruption can actually increase, as when molten rock reaches ground level it can shoot ash kilometres away from the crater.
The volcano began spewing lava at around 9pm last Thursday night (local time), forcing hundreds of residents on Hawaii's Big Island to evacuate.
