[火山活动]美国夏威夷火山18日午夜前喷发,熔岩料流向公路影响居民疏散

美國夏威夷基拉韋厄火山噴發持續,一名居民被噴出的熔岩燒傷。另外新噴出的熔岩預料流向多條主要公路,影響居民疏散。

基拉韋厄火山周五午夜前再次噴發,火山灰噴上約一萬呎高空,地面裂縫亦增至最少22道。熾熱的熔岩不斷從部分裂口噴出,其中兩個裂口的熔岩匯聚成一道岩漿,往東南方面迅速流動。

當地民防組織表示,若熔岩保持流向,將流往一條用於疏散居民的沿岸主要高速公路。到時有可能需要重開一條在2014年因熔岩流出而封閉的道路,供民眾疏散。夏威夷國民警衛隊警告,必要時會實行強制撤離。

火山新一輪噴發活動,造成最少一名居民嚴重受傷。夏威夷州州長辦公室發言人表示,傷者當時坐在自己住所三樓陽台上,地面噴出的熔岩濺到他腿上,傷勢嚴重。

基拉韋厄火山月初噴發至今,當地逾四十棟建築被毀壞,附近兩千居民被撤離。

夏威夷大島幾勞亞火山(Kilauea volcano)大規模噴發邁入20天,近日滾燙岩漿流入地勢較低的東斷裂帶,美國地質調查局(USGS)則是分享當地影像,除了噴發的岩漿,其地表縫隙竟然冒出藍色火焰,畫面看起來相當駭人!

美國地質調查局提供影片中,岩漿流入較低的東斷裂帶,地表被熔融後,其縫隙中竟然泛起藍色火焰。

美國地質調查局指出,會有藍色火焰的現象,就是因植物與灌木著火時會釋放甲烷,甲烷氣體滲入地表的裂縫,再加上熱氣時,引燃後出現藍色火焰。

不過,地質學家提醒,甲烷氣體並非都是這麼美,甲烷被引爆時可能會使巨大石塊飛向空中;美國地質調查局則是持續觀察火山噴狀況,但目前依舊沒有減緩趨勢。

Kīlauea Volcano Lower East Rift Zone
Vigorous eruption of lava continues from the lower East Rift Zone fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fissures 22 and 13 continue to feed lava flows extending south to the lava ocean entry. Signals recorded
on stations in the LERZ indicate that the lava ocean entry remained active overnight.
Fissure 21 is feeding an 'a'ā flow that has continued to advance to the northeast on PGV property.
However, the rate of advance has slowed overnight coincident with an observed decline in the vigor of fountaining at Fissure 21. Fissure 7 activity has increased overnight, producing a large spatter rampart
over 100 feet tall from fountains reaching 150-200 feet. The fountains fed a perched pāhoehoe flow
20-40 feet thick, and ultimately a flow that had turned south toward the coast last night.
Large cracks were observed overnight on Kupono St. about 360 yards north of Malama St, near Fissure 9. Fissure 8 had three vents active overnight that were spattering and flaming, and have doubled in size over the past 24 hours. Fissure 6 was inactive overnight.

Haze from the Kilauea volcano eruption in Hawaii blanketed the Marshall Islands 3,700 kilometres (2,300 miles)
away on Sunday, as officials warned it would continue moving west.
The haze, a phenomenon known as “vog” or volcanic smog, is spreading across Micronesia, the US National
Weather Service based in Guam said.
The volcano on Hawaii’s Big Island is now in its fourth week of eruptions.

27 May 2018  Kīlauea Volcano Summit
Ash continued to erupt intermittently from the vent within Halema?uma?u crater, at Kīlauea's summit, but no significant
ash columns have been produced since noon on Sunday. Observations from the ground, by UAV, and by satellite
during the past week have documented retreat of the summit vent walls due to collapse of the steep conduit and rim.              Trade winds are causing ash fall to the southwest, but are diminishing in intensity as wind patterns shift late Sunday and early Monday. This may bring ashfall to communities around the summit area.
