夏威夷基拉韦厄火山于周四再次喷发,这是过去一年半以来该火山的第45次同类喷发活动。

据美国地质调查局(USGS)消息,当地时间凌晨1点30分左右,熔岩首次从火山中喷涌而出。由美国地质调查局运营的基拉韦厄火山直播画面显示,18个多小时后,明亮的橙色熔岩流仍在持续喷向地面。

夏威夷火山观测站在本次喷发启动后发布的多份通报中提到,基拉韦厄北部喷口喷出的喷泉在峰值时高达1000英尺。喷发初期的几个小时内,喷泉高度维持在500英尺左右,之后一度升至700英尺。

观测站表示,喷发开始约一小时后,基拉韦厄的整体烟柱——包括火山内部喷出的熔岩、气体、蒸汽和火山灰——升至至少海拔16500英尺的高度,这也是本次喷发的最高高度。

基拉韦厄火山坐落于夏威夷大岛广袤的火山国家公园内,是地球上最活跃的火山之一。自2024年12月以来,它定期喷发,吸引游客前往这片大型保护区,亲眼目睹熔岩流腾空的景象。

官员们表示,由于喷发活动被限制在基拉韦厄内部的哈莱马乌马乌火山口内,并未对岛上的房屋、建筑或民众构成威胁。据美国地质调查局数据,2024年12月以来的多数喷发持续时间不超过一天。

该机构已针对本次喷发发布火山监视警报和“橙色”航空警报,这意味着喷发“造成的危害有限”,要么未产生火山灰排放,要么仅存在少量排放。美国国家气象局还针对火山下风方向的社区发布了夜间火山灰沉降警报。

官员们指出,每次喷发产生的火山气体进入大气后可能引发呼吸系统问题。这种相互作用会污染下风区域的空气,这一过程被称为“火山烟雾(vog)”。他们还警告称,基拉韦厄熔岩喷泉形成的火山灰、浮石和其他玻璃质物质碎片,可能会根据其颗粒大小,飘散至远离火山喷发点的区域。

“居民和游客应尽量减少接触这些碎片,它们可能会刺激皮肤、眼睛和呼吸系统。”美国地质调查局说道。这些碎片被称为“火山碎屑(tephra)”。

今年3月基拉韦厄的一次喷发导致国家公园和附近一条高速公路临时关闭,夏威夷官员为可能受关闭影响或遭遇空中火山灰沉降的居民和游客开放了避难所。官员们表示,避难所仅在短时间内投入使用,但在之前的一些喷泉喷发事件中,曾有大量火山灰沉降。

Hawaii’s Kilauea volcano erupts yet again, with lava fountains 1,000 feet above ground

Hawaii’s Kilauea volcano erupted again on Thursday, marking the 45th episode of its kind over the last year and a half.

Lava began to burst from the volcano in the early morning, around 1:30 a.m. local time, according to the United States Geological Survey. A livestream of Kilauea, which is operated by USGS, showed bright-orange molten streams shooting up from the ground more than 18 hours later.

The fountains from Kilauea’s northern vents reached 1,000 feet high at their peak, said the Hawaiian Volcano Observatory in one of multiple updates issued since the current eruption started. They hovered at around 500 feet, and, later, 700 feet, for several hours shortly after the episode initially got underway.

Kilauea’s overall plume — which refers to the lava, gas, steam and ash expelled from within the volcano — climbed to at least 16,500 feet above ground level about an hour into the eruption, according to the observatory. That was its highest point this time.

Located inside the Big Island of Hawaii’s sprawling Volcanoes National Park, Kilauea is among the most active volcanoes on Earth. It has been erupting periodically since December 2024, drawing tourists to the massive protected area to see its lava flows soar overhead in real life.

Because the eruptions have been confined to the Halemaʻumaʻu crater within Kilauea, they have not posed threats to homes, buildings or people on the island, officials have said. Most episodes since December 2024 have lasted no longer than one day, according to USGS.

The agency has issued a volcano watch and “orange” aviation alert for this episode, meaning the eruption “poses limited hazards” and either has no ash emissions associated with it, or minor ones. The National Weather Service also issued an ashfall advisory overnight for communities downwind of the volcano.

Officials noted that the volcanic gas produced in each eruption can cause respiratory problems once it enters the atmosphere. The interaction pollutes air downwind, in a process known as “vog.” They also warned that fragments of volcanic ash, pumice and other glassy materials created by Kilauea’s lava fountains may fall far from the site of the volcano, depending on their size.

“Residents and visitors should minimize exposure to these fragments, which can cause skin, eye, and respiratory irritation,” USGS said. The fragments are called “tephra.”

An eruption in March at Kilauea prompted temporary closures at the national park and along a nearby highway, as Hawaii officials opened a shelter for residents and tourists who may have been affected by the closures or the tephra falling from the sky. Officials said the shelter was only necessary for a short period of time, but significant ash fell during some previous fountaining episodes.
