冰岛雷恰角半岛再现火山喷发,为今年第六次
中新社北京8月23日电 雷克雅未克消息:冰岛西南部雷恰角半岛当地时间22日再次发生火山喷发,这是当地自2023年12月以来发生的第六次火山喷发。
据冰岛气象局消息,当地时间22日晚9时许,松兹努克火山口开始喷发,东部出现裂缝,喷涌而出的气体上升至1公里的高度,并向南扩散。裂缝迅速朝北部和南部蔓延,总长度约为3.9公里。目前,地震活动主要出现在裂缝北部。
现场直播画面显示,炽热的岩浆从地面喷涌而出,明亮的黄色和橙色与黑暗的夜空形成鲜明对比。
冰岛外交部在社交媒体上表示,此次火山喷发对当地影响有限,火山附近格林达维克镇的居民已撤离,未影响国际国内航班,但旅游胜地“蓝湖”再度关闭。
冰岛气象局此前持续监测该火山状态。喷发前一段时间,该地区地震活动愈加频繁,出现和上次喷发前几天观察到的类似现象,检测到的岩浆量则比以前更大。
这座火山于2023年12月18日,2024年1月14日、2月8日、3月16日和5月29日发生喷发。今年5月29日开始的喷发状态持续24天。
据路透社报道,雷恰角半岛居民人数约为3万,占冰岛总人数的8%。冰岛地处大西洋中脊火山活跃带,火山多、地质活动频繁。
专家分析
此次火山喷发再次引发了人们对冰岛火山活动的关注。中国地质大学火山研究专家李教授表示,雷恰角半岛的火山活动近年来较为活跃,这与该地区地质构造和板块运动有关。他指出,冰岛位于大西洋中脊火山活跃带,地壳运动频繁,岩浆活动活跃,导致火山喷发频发。
李教授还表示,此次火山喷发规模相对较小,对周边地区的影响有限。但需要注意的是,火山喷发会释放大量的火山灰和气体,对航空运输、环境和气候等方面可能造成一定影响。
后续关注
此次火山喷发再次提醒人们,自然灾害的不可预测性。未来,需要加强对火山活动的监测和预警,做好应急准备,最大程度地减少火山喷发带来的损失。
此外,此次火山喷发也为科学家们提供了宝贵的科研机会,可以深入研究火山喷发机制、岩浆活动规律等,为更好地预测和应对火山灾害提供理论依据。

Reykjanes Peninsula in Iceland Erupts Again, Marking the Sixth TimeThis Year
Keywords: Iceland, eruption, six times
Content:
BEIJING, Aug. 23 (Xinhua) — The Reykjanes Peninsula in southwestern Iceland experienced another volcanic eruption on Tuesday, markingthe sixth eruption in the region since December 2023.
According to the Icelandic Meteorological Office, the eruption began at around 9 p.m. local time at the Sundhnúkagígur crater, with a fissure opening up to the east, spewing gas up to 1 kilometer high and spreading southwards. The fissure quickly extended north and south, reaching a total lengthof approximately 3.9 kilometers. Seismic activity is currently concentrated north of the fissure.
Live footage shows incandescent lava gushing from the ground, creating a stark contrast against the dark night sky with its bright yellow and orange hues.
The Icelandic Ministry for Foreign Affairs stated on social media that the eruption has had limited impact on the area, with residents of the nearby town of Grindavík already evacuated. International and domestic flights remain unaffected, but the popular tourist destination, the Blue Lagoon, has been closed again.
The Icelandic Meteorological Office had been continuouslymonitoring the volcano’s activity. In the period leading up to the eruption, seismic activity in the region intensified, mirroring observations made days before previous eruptions, with a larger volume of magma detected than in previous instances.
The volcano had previously erupted on December 18, 2023, January 14, 2024, February 8, 2024, March 16, 2024, and May 29, 2024. The eruption that began on May 29 lasted for 24 days.
According to Reuters, the Reykjanes Peninsula is home to approximately 30,000 residents, accounting for 8% of Iceland’s total population. Iceland, situated on the Mid-Atlantic Ridge, a volcanically active zone, is characterized by numerous volcanoes and frequent geological activity.
Expert Analysis
The eruption hasonce again brought attention to Iceland’s volcanic activity. Professor Li, a volcanology expert at China University of Geosciences, stated that the Reykjanes Peninsula has witnessed heightened volcanic activity in recent years, attributing this to the region’s geological structure and plate tectonics. He emphasized that Iceland lies on theMid-Atlantic Ridge, a volcanically active zone characterized by frequent crustal movements and active magma activity, leading to frequent volcanic eruptions.
Professor Li also noted that the current eruption is relatively small in scale and has limited impact on surrounding areas. However, he cautioned that volcanic eruptions release significant amounts of volcanic ash and gases, which can potentially affect air travel, the environment, and climate.
Future Focus
This eruption serves as a reminder of the unpredictable nature of natural disasters. In the future, it is crucial to strengthen monitoring and early warning systems for volcanic activity, prepare for emergencies, and minimize the losses caused by volcanic eruptions.
Furthermore, this eruption presents valuable research opportunities for scientists to delve deeper into the mechanisms of volcanic eruptions, the patterns of magma activity, and other aspects, providing theoretical foundations for better prediction and mitigation of volcanic disasters.
