Kilauea, one of the most active volcanoes in the world, began erupting on Wednesday after a three-month pause, displaying spectacular fountains of mesmerizing, glowing lava that's a safe distance from people and structures in a national park on the Big Island.

A glow was detected in webcam images from Kilauea's summit early in the morning, indicating that an eruption was occurring within the Halemaumau crater in the summit caldera, the U.S. Geological Survey's Hawaiian Volcano Observatory said.

The images show fissures at the base of the crater generating lava flows on the crater floor's surface, the observatory said.

Before issuing the eruption notice, the observatory said increased earthquake activity and changes in the patterns of ground deformation at the summit started Tuesday night, indicating the movement of magma in the subsurface.

"We're not seeing any signs of activity out on the rift zones right now," said Mike Zoeller, a geologist with the observatory. "There's no reason to expect this to transition into a rift eruption that would threaten any communities here on the island with lava flows or anything like that."

All activity was within a closed area of Hawaii Volcanoes National Park.

"The lava this morning is all confined within ... the summit caldera. So plenty of room for it still to produce more without threatening any homes or infrastructure," said park spokesperson Jessica Ferracane. "So that's the way we like our eruptions here."

She said park officials are bracing for crowds to arrive because visitors can see the eruption from many overlooks.

"Kilauea overlook was spectacular this morning," she said of the vast lava lake. "It was molten red lava. There's several areas of pretty robust fountaining. It's just really, really pretty."

The lava lake, covering the crater floor over lava that remained from previous eruptions, measured about 371 acres (150 hectares) at about 6 a.m., Zoeller said. It measured about 4,300 feet (1,300 meters) wide.

Word was getting out and parking lots were starting to fill up at the park, Ferracane said, adding that she expected long lines getting into the park by evening.

Since the park is open 24 hours a day, visitors can beat the crowds by visiting between 9 p.m. and sunrise, Ferracane said.

She reminded visitors to stay out of closed areas and remain on marked trails for safety reasons, including avoiding gases from the eruption.

Residents of Pahala, 20 miles (30 kilometers) downwind of Kilauea's summit, reported a very light dusting of gritty fine ash and "Pele's hair"—glass particles that form when lava erupts from a fissure and rapidly cools—named for the Hawaiian goddess of volcanoes, the observatory said.

Two small earthquakes jolted Janice Wei awake. As a volunteer photographer for the park who lives in the nearby town of Volcano, she was able to see fountains she estimated to be 150 feet (46 meters) high at around 4:30 a.m.

She said she saw about 15 fountains, which were dying down by mid-morning.

Fountain heights decreased to 13 feet to 30 feet (4 meters to 9 meters) in the afternoon, according to the observatory.

The volcano's alert level was raised to warning status and the aviation color code went to red as scientists evaluate the eruption and associated hazards.

Kilauea, Hawaii's second largest volcano, erupted from September 2021 until last December. For about two weeks in December, Hawaii's biggest volcano, Mauna Loa, also was erupting on Hawaii's Big Island.

After a short pause, Kilauea began erupting again in January. That eruption lasted for 61 days, ending in March.

This eruption is looking very similar, Zoeller said, "This eruption is following a very similar playbook to the last three that we've seen here since 2020."

A 2018 Kilauea eruption destroyed more than 700 homes.

Before the major 2018 eruption, Kilauea had been erupting since 1983, and streams of lava occasionally covered farms and homes. During that time, the lava sometimes reached the ocean, causing dramatic interactions with the water.

Philippines on alert as volcano spews ash

Philippine scientists said that a "hazardous eruption" of a volcano in the archipelago could be days or weeks away, and urged the evacuation of nearby residents from their homes.

Hundreds of families living around Mount Mayon in central Albay province are expected to be moved to safer areas after the Philippine Institute of Volcanology and Seismology raised the alarm.

Mayon, a near-perfect cone located about 330 kilometers (205 miles) southeast of the capital Manila, is considered one of the most volatile of the country's 24 active volcanoes.

The seismology agency said it observed three fast-moving avalanches of volcanic ash, rock and gases, known as pyroclastic density currents (PDCs), on Mayon's slopes on Thursday.

There are "increased chances of lava flows and hazardous PDCs... and of potential explosive activity within weeks or even days", the agency said, raising the alert level from two to three on a scale of zero to five.

"All necessary preparations are being done," said Eugene Escobar, the Albay provincial disaster management agency's officer-in-charge.

Rommel Negrete, an officer for the agency, said residents would be evacuated from Anoling village on the volcano's slopes.

Meanwhile, Taal volcano, located about 50 kilometers (31 miles) south of Manila, has been releasing sulfur dioxide this week, blanketing surrounding areas in smog and prompting warnings for people to stay indoors.

Steam-rich plumes have been recorded rising two kilometers (1.2 miles) into the sky, the seismology agency said on Thursday. It has left the alert level at one.

Earthquakes and volcanic activity are not uncommon in the Philippines due to its position on the Pacific "Ring of Fire", where tectonic plates collide deep below the Earth's surface.

Five years ago, Mayon displaced tens of thousands of people after spewing millions of tons of ash, rocks and lava.

The most powerful explosion in recent decades was the 1991 eruption of Mount Pinatubo, about 100 kilometers (62 miles) northwest of Manila, which killed more than 800 people.

It sent out an ash cloud that traveled thousands of kilometers in a matter of days and was blamed for damaging nearly two dozen aircraft.
