Hawaii's Mauna Loa, The World's Largest Active Volcano, Erupts After 38 Years

Smoke filled the Hawaiian night sky on Sunday, 

glowing a brilliant red, signaling the eruption of the world's 

largest active volcano. Mauna Loa, which means 

"tall mountain" in Hawaiian, erupted at approximately 11:30 p.m. 

local time on Sunday. According to the US 

Geological Survey, it was showing signs of disturbance since September.

The federal agency has designated the volcano's alert

level as "alert," meaning that "a dangerous 

eruption is imminent, ongoing, or suspected."
