According to the Hawaiian Volcano Observatory, over the past day, vents in the southwest portion of the caldera have continued producing a fan of lava flows covering the southwest portion of the crater floor, with sustained lava fountaining as high as 100 feet.

Molten rock began shooting from the volcano before dawn on Monday when fissures opened in the caldera floor and propelled lava 295 feet (90 meters) into the air. The red liquid formed tall fountains and then spread across 650 acres (263 hectares). The Hawaiian Volcano Observatory estimated the lava was about 1 yard (1 meter) thick.

The Kilauea volcano on Hawaii's Big Island spewed lava on Christmas Day (December 25), keeping up its rumbling despite the alert level at the volcano being lowered.

Hawaii's Kilauea volcano, one of the most active volcanoes in the world, awoke Monday. Video from the USGS shows lava spewing into the air while also pooling around the eruption site.

The eruption occurred about 2:20 a.m. local time Monday within Halemaʻumaʻu crater inside Kilauea's summit caldera, a closed area of Hawaii Volcanoes National Park.

One of the world's most active volcanoes sprang into life again Monday, spewing columns of lava 80 meters (260 feet) above Hawaii, US vulcanologists said.

What had been low-level lava flows since Thursday morning became more vigorous fountaining Friday evening, according to the U.S. Geological Survey’s Hawaii Volcano Observatory.
