An eruption began in the summit caldera of Hawaii’s Mauna Loa, the world’s largest active volcano, on Sunday night, the U.S. Geological Service’s volcanic activity service said.
“At this time, lava flows are contained within the summit area and are not threatening downslope communities,” the notification said.
However, the notification warned, based on previous events, that the early eruption stages of this volcano can be very dynamic and the location and advance of lava flows can change rapidly.
The volcano alert level was upgraded from an “advisory” to a “warning.”
The notification added that the Hawaiian Volcano Observatory would conduct aerial reconnaissance as soon as possible to assess hazards and better describe the eruption.
