印度尼西亚阿纳克火山喷发致数十万乘客滞留

印度尼西亚阿纳克火山本周发生喷发，大量火山灰升入高空，导致超过30万名乘客的航班受到中断影响1。印度尼西亚灾难管理机构表示，当前喷发不存在较大规模火山体坍塌的可能性，主要威胁来自空中火山灰对航空器的危害1。

这次喷发引发了人们对历史灾难重演的担忧。1883年的喀拉喀托火山大喷发造成了约3.5万人的死亡，其中超过90%的遇难者死于随后的海啸1。那次喷发产生的爆炸声是有记录以来最大的声音，在距离约5000公里外的毛里求斯仍能听到1。喷发释放的火山灰微粒漂流至距喷发地3000多公里的澳大利亚，而浮石在海中漂流超过一年，至1884年7月才到达东非桑给巴尔1。1883年喷发还导致全球温度下降约0.3°C并持续数年，期间月球呈现蓝色、日落呈现绿色1。相比之下，2018年阿纳克火山喷发导致火山体坍塌，引发的海啸致400多人死亡1。

Indonesia's Anak Krakatau volcano has erupted this week, sending ash columns into the sky and triggering widespread aviation disruptions 1. More than 300,000 passengers have been affected by the cancellation of hundreds of flights as a result of the volcanic activity 1.

The current eruption has raised questions about whether a repeat of the catastrophic 1883 Krakatau eruption is possible 1. That historical event killed approximately 35,000 people, with more than 90 percent of those deaths caused by the tsunami it generated 1. The 1883 explosion was so powerful that it produced the loudest sound ever recorded, audible as far away as Mauritius approximately 5,000 kilometers away 1. The eruption triggered tsunamis with waves exceeding 2 meters in height and caused global temperatures to drop approximately 0.3 degrees Celsius for several years 1. The atmospheric effects were severe enough that the moon appeared blue and sunsets turned green 1. Volcanic ash particles dispersed more than 3,000 kilometers away to Australia, while pumice drifted for over a year before reaching Zanzibar in East Africa by July 1884 1.

Indonesia's disaster management agency has stated that the current eruption shows no signs of a major collapse 1. The primary threat from this week's activity is the hazard posed by airborne volcanic ash to aircraft 1. A more recent eruption in 2018 resulted in a partial volcanic collapse that triggered a tsunami killing over 400 people 1.
