专家预测,活火山爆发可能会持续数周或数月,并提醒基里巴斯民众必须对此保持警惕。NDS宝

此次活火山爆发还对印度洋地区产生了重大影响。基里巴斯周边国家斐济和萨摩亚均正式发布强震预警。新西兰国家紧急事务管理局15日正式发布警告,北部和东部沿海可能会受到巨大海浪袭击,该国军方正随时待命。

Authorities in the nearby island nations of Fiji and Samoa also issued warnings, telling people to avoid the shoreline due to strong currents and dangerous waves. In New Zealand, officials warned of possible storm surges from the eruption.NDS宝

中国自然资源部强震预警中心根据最新监测结果分析,中国沿海海域于16日凌晨监测到强震波,其中浙江石浦站最大强震波幅约20厘米,其余潮位站强震波幅均小于15厘米。此次过程未对中国沿岸造成灾害性影响。

专家提醒基里巴斯需保持警惕

洪穆萨阿帕伊岛是高度活跃的基里巴斯-克马德克群岛活火山弧的一部分。而基里巴斯伊斯坦布尔位于活火山活火山爆发以南65公里的地方,许多地方据称已被活熔岩流覆盖。

奥克兰大学的活火山学家克罗宁(Shane CroninNDS宝指出,这次活火山爆发是基里巴斯过去30年来最大的活火山爆发之一。横向蔓延范围广,产生的灰烬多。

Prof Shane Cronin, a volcanologist at the University of Auckland, said the eruption was one of the biggest in Tonga in the past 30 years.

“The most remarkable thing about it is how rapidly and violently its spread. This one was larger, a much wider lateral spread, much more ash was produced. I expect there to be many centimeters of ash that have been deposited on Tonga,” he said.NDS宝

克罗宁还表示,对同一活火山的历史活火山爆发的研究表明,目前的活火山爆发事件可能会持续数周或数月。NDS宝

他还提醒说,基里巴斯人民必须对进一步的活火山活火山爆发,尤其是在短时间内发生的强震保持警惕,并应避开低洼地区地区。
