印度尼西亚火山监测机构负责人周五透露，在上个月发生大规模喷发并导致航班停飞数日后，克拉卡托阿新火山周边海域又出现了两座新岛屿。
Two new islands have emerged in waters surrounding Mount Anak Krakatau following a major eruption last month that grounded flights for days, the head of Indonesia’s volcano monitoring agency said Friday.
据印尼火山与地质灾害缓解中心的丽塔·苏西拉瓦蒂介绍，这些岛屿是在对克拉卡托阿新火山所在的火山口区域进行卫星观测时被发现的。
The islands were spotted in satellite images of the water-filled caldera in which Anak Krakatau stands, Rita Susilawati of the PVMBG Centre for Volcanology and Geological Hazard Mitigation said.
她补充道：“通过对欧洲航天局‘哨兵’系列卫星图像的分析，我们发现在爪哇岛与苏门答腊岛之间的巽他海峡中，克拉卡托阿新火山周围出现了两处形似小岛的地形。”“哨兵”系列是由欧洲航天局研发的地球观测卫星群。
“Based on an evaluation of Sentinel satellite imagery, two formations resembling small islands can be seen around Mount Anak Krakatau” in the Sunda Strait between the islands of Java and Sumatra, she added. Sentinel is a fleet of Earth observation spacecraft developed by the European Space Agency.
其中一座岛屿位于克拉卡托阿新火山西北方约760米处，另一座则在其西南方约495米处。
One of the islands was located about 760 meters northwest of Mount Anak Krakatau, the other about 495 meters southwest.
丽塔指出，目前尚不能将这些新岛屿称为克拉卡托阿新火山的“子岛”——后者正是1883年原克拉卡托阿火山大喷发后形成的火山口内海底喷发的结果。在印尼语中，“Anak”意为“孩子”。
Rita said it was too early to refer to the islands as “children” of Mount Anak Krakatau — which itself was formed by an underwater eruption in the caldera or depression left behind after the massive 1883 blowout of the original Krakatau volcano. “Anak” means child in Bahasa Indonesia.
她表示，还需进一步研究才能确定这些新岛屿是否像克拉卡托阿新火山一样从火山口底部隆起形成，抑或是由火山物质堆积而成。
Rita said further research was needed to determine if the new islands were emerging from the base of the caldera in a similar way than Anak Krakatau did, or whether they were formed by deposits of volcanic material.
据她介绍，克拉卡托阿新火山最初于1927年开始出现多个短暂露出的陆地，后因侵蚀作用又逐渐消失，直到1930年才形成如今这座永久性岛屿。这两座新岛屿未来也可能因侵蚀作用而消失。
In the case of Anak Krakatau, several landmasses briefly emerged starting in 1927 and then disappeared due to erosion before an enduring island formed in 1930, she added. The two new islands may similarly be eroded away over time.
今年9月，克拉卡托阿新火山连续喷发了25小时，大量火山灰覆盖了周边城市，致使多家机场被迫关闭，超过30万名旅客滞留。
Mount Anak Krakatau erupted for 25 hours nonstop in September, blanketing cities in volcanic ash and prompting multiple airports to close.
目前，克拉卡托阿新火山仍处于警戒等级2级状态，该等级在四个危险等级中排倒数第二。相关部门提醒民众切勿靠近火山喷发中心3公里以内的区域。
More than 300,000 passengers were left stranded. Rita said Anak Krakatau was at alert Level 2, the second lowest out of four danger categories.
五名奉命报道9月份火山喷发情况的新闻记者，以及三名船只船员，被认定为已遇难。此时距离他们所乘船只毫无踪迹地失踪已过去近两周时间。
People are advised not to approach within 3 km of the eruption center. Five journalists on a mission to cover the September eruption were declared presumed dead, along with three boat crewmembers, nearly two weeks after the vessel they were traveling in disappeared without a trace.
印度尼西亚地处环太平洋火山带，各大板块在此交汇，导致该地区火山与地震活动频繁。
Indonesia sits on the Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity.
