Hawaii's second-largest volcano is likely to resume erupting soon after a brief pause. The U.S. Geological Survey said Saturday that a shallow earthquake storm had been detected under the summit of Kilauea. Scientists just said Tuesday that lava had stopped flowing after 61 days of volcanic activity, but Kilauea is living up to its reputation as one of the world’s most active volcanoes.

The Alaska Volcano Observatory raised the alert level for Tanaga Volcano following a swarm of earthquakes on Tuesday. The remote volcano has not erupted since 1914.

The Kilauea volcano on Hawai'i's Big Island has been erupting again for nearly two weeks, creating lava fountains and a glow visible with the Landsat 8 satellite.

Lava from Kilauea is spurting high into the air and spreading out across the Hawaii volcano’s summit crater floor.

Kilauea summit is inside Hawaii Volcanoes National Park and away from residential communities.

Hawaii's Kilauea began erupting inside its summit crater Thursday after scientists detected a glow in webcam images inside the Halemaumau crater.

The latest eruption began less than one month after the volcano and its larger neighbor Mauna Loa stopped releasing lava​.

Hawaii’s Kilauea volcano has begun erupting inside its summit crater.

Hawaii's Kilauea began erupting inside its summit crater Thursday, the U.S. Geological Survey said, less than one month after the volcano and its larger neighbor Mauna Loa stopped releasing lava. The Hawaiian Volcano Observatory detected a glow in webcam images indicating Kilauea had begun erupting inside Halemaumau crater at the volcano's summit caldera, the agency said. Kilauea’s summit is inside Hawaii Volcanoes National Park and away from residential communities.

The mainland isn't the only one experiencing a major winter storm. Just a week after Mauna Loa stopped erupting, Winter Storm Warnings were issued for Hawaii's Big Island.

Scientists lowered the alert level for the Mauna Loa volcano on Hawaii's Big Island from a warning to a watch on Saturday and said the mountain's first eruption in nearly 40 years may soon end. The U.S. Geological Survey’s Hawaiian Volcano Observatory said in a bulletin that the eruption on the mountain's northeast rift zone was continuing, but lava output and volcanic gas emissions were “greatly reduced.” “High eruption rates will not resume based on past eruptive behavior and current behavior suggests that the eruption may end soon,” the observatory said.

Mauna Loa was still erupting Thursday morning, but the lava that was feeding the flow heading toward the crucial road has been cut off.

Scientists in Hawaii say lava from the world’s largest volcano is no longer an imminent threat to the main highway across the Big Island.

Lava from the world's largest volcano is no longer an imminent threat to the main highway across the Big Island of Hawaii, scientists said Thursday, a development that was a welcome reprieve for motorists who depend on the road. Mauna Loa was still erupting Thursday morning, but the lava that was feeding the flow heading toward the crucial road has been cut off, likely because of a reduced production rate, said David Phillips, deputy scientist-in-charge at U.S. Geological Survey’s Hawaiian Volcano Observatory. “That’s good news for us,” Hawaii County Mayor Mitch Roth said.

An endangered nocturnal seabird fledgling was seen on camera for the first time emerging from a burrow on a volcano, officials say.

“Pele brings change and life, in so many ways.”

Many people on the Big Island of Hawaii are bracing for major upheaval if lava from Mauna Loa volcano blocks the quickest route connecting two sides of the island.

Scientists say it's not possible to forecast how long the eruption at Hawaii's Mauna Loa volcano will last. David Phillips of the Hawaii Volcano Observatory notes that the previous eruption in 1984 lasted a little over three weeks. (Dec. 2)
