WATCH: Hawaii’s Kilauea volcano erupts again

The U.S. Geological Survey said Thursday that Hawaii's Kilauea began erupting again. 

The eruption of Kilauea began within the Halemaʻumaʻu crater just after 4:30 p.m. HST on Jan. 5, according to USGS. It's less than a month after nearby Mauna Loa spewed lava for two weeks at the end of November. 

The USGS raised the alert level for Kilauea to "WARNING/RED." 

"High levels of volcanic gas are the primary hazard of concern, as this hazard can have far-reaching effects down-wind," according to a hazard analysis from USGS. 

Kilauea last erupted for 16 months, starting in Sep. 2021.
