"Officials said late Saturday that the lava had entered the ocean, and advised all people to avoid the area because of a new hazard: laze"

Laze occurs when hot lava meets the ocean, sending a plume of hydrochloric acid and steam — along with fine glass particles — into the air.

Laze plumes travel with the wind and can shift directions without warning, the county civil defense agency said.
