A large explosion in Hawaii's Kilauea volcano could lead to an explosive eruption and send boulders, rocks and ash into the air in the coming weeks, the US Geological Survey (USGA) said on Wednesday. No homes or roadways are threatened by this flow.

Nearby resident Richard Schott, 34, watched from a police checkpoint as the eruption churned just over a ridgeline and behind some trees.
Rock samples and chemical analysis show the lava "so far looks to be similar to the 1955 lava chemistry", Tina Neal, the Hawaiian Volcano Observatory scientist-in-charge, told reporters Friday, according to CNN affiliates KGMB and KHNL.
As a precaution, plant workers last week removed 50,000 gallons (189,265 liters) of a flammable liquid stored at the site.
