Hawaii’s Kilauea volcano erupted early on Thursday morning, blasting a plume of ash and debris 30,000 feet into the air.

“5 AM eye-opener at the the Kīlauea Volcano summit,” the U.S. Geological Service tweeted. “HVO and Park Staffs previously evacuated.”

A red aviation code had already been issued – warning pilots to avoid the potentially damaging ash cloud. The lava seeping from the volcano has forced the evacuation of nearly 2,000 people.

Kilauea is one of five active volcanoes on the island of Hawaii. An eruption in 1924 killed one person and sent rocks, ash and dust into the air for 17 days.
