在现场的智利圣地牙哥大学的科德罗(Raul Cordero)说:「能见度超棒。」他在格林威治时间7时46分亲眼目睹日全食,「火环食」(Ring of Fire)阶段持续超过40秒。
当月球经过太阳与地球之间会发生日食,如果三者呈一直线就会发生日全食。
只有少数的科学家、专家和观光客亲眼看到此奇景,观光客付了4万美元,才享有此特权。

美国航空暨太空总署(NASA)在南极联盟冰川营地(the Union Glacier camp)扎营和直播日全食。日食现象从格林威治时间早上7点开始,至8点06分结束。
NASA表示,南半球部分地区可以看到日偏食,包括圣赫勒拿岛、纳米比亚、莱索托、南非、智利、新西兰和澳洲。

印尼东爪哇省(East Java)塞梅鲁火山(Mount Semeru)暌违近1年于4日下午再度喷发,造成至少1人死亡和41人严重灼伤,附近数千名民众被迫紧急逃离。
当局表示,有2人据报失踪,另有8人受困在一栋建筑物内。在家园被火山灰和熔岩摧毁后,东瓜哇省卢马姜县(Lumajang)的Curah Kerobokan村遭重创,超过300户家庭在临时收容所避难。
Mount Semeru in Lumajang Regency, East Java erupted, on Saturday, December 4,at around 3.00pm local time. The Volcanic Ash Advisory Center has issued a warning after a volcanic ash plume rose up to an estimated 40000ft, raining down on the residents below.
地方当局表示,由于冷熔岩和火山灰抵达居住社区,其他邻近村庄居民仓皇逃离。
救难人员历经一小时搜索后,在Curah Kerobokan村找到一具遗体。
卢马姜县副县长马斯达尔(Indah Masdar)表示,有41人遭炽热岩浆严重灼伤,有两名伤者是怀孕妇女。她又说,由于冷熔岩流摧毁一座桥梁,卢马姜县的联外交通中断。
印尼国家灾害应变总署表示,它已派遣一支救援团队前往协助临时避难所的灾民,但火山灰形成的浓厚碎屑阻止他们抵达目的地。
印尼气象气候暨地球物理局(BMKG)公布的影片显示,海拔3676公尺的塞梅鲁火山于当地时间4日下午3时喷发后,包括数十名小孩在内的居民慌张逃难。喷烟直窜至1万2000公尺高空,熔岩往下流至距火山口500公尺以外远处。

西班牙加那利群岛拉帕尔马岛(La Palma)老峰火山(Cumbre Vieja)9月喷发以来一直处于活跃状态,滚烫的岩浆持续蔓延至市区,吞没无数房舍与道路,当地最新照片出炉,只见岩浆铺天盖地而来,所到之处无不化为废墟。
Around 100 homes have been destroyed on the Spanish Canary Island of La Palma after the Cumbre Vieja volcano spectacularly erupted on Sunday, sending rivers of lava down the hillside toward the Atlantic Ocean.
根据《CNN》报导,老峰火山岩浆持续蔓延至低海拔地区,现以每秒1公尺的速度吞噬土地,在爆发之初已完成撤离的村庄残馀建筑物接连被淹没,消失在滚滚而来的岩泥与灰烟中。
按当局最新发布的资讯,熔岩自火山处涌上地表,因重力作用流淌而下,目前已于该岛西海岸的两处分别注入大西洋,并形成新的海岸线。
据统计,自火山爆发以来,岩浆已陆续摧毁超过1200间房舍与300多座建筑,更吞没了作为岛上经济命脉的农田,岛上总人口8万人中约有6000多名灾民流离失所,未来命运仍不可知。

西班牙火山熔岩摧毁320栋建筑

(早报讯)欧洲的火山观测所周三(9月22日)表示,西班牙拉帕尔马岛一座火山喷发的熔岩,摧毁了320栋建筑物和超过154公顷的土地。
法新社报道,西班牙拉帕尔马岛一座火山星期天(19日)喷发,熔岩喷向数百公尺高空,至今约有6000人被迫逃离家园。
这座火山位于人烟稀少的卡贝萨德瓦卡地区一处树木繁茂的山坡。炽热的橘红色熔岩流侵入树林与农田,到达地势较低的地面后逐渐散开来。
专家指,若岩浆按照目前的速度流向海岸,很可能将在今天或周四抵达海岸,并警告可能出现爆炸效应。
加那利群岛火山学研究所(Involcan)相信,该座火山喷发的时间可持续“24天至84天”。
拉帕尔马岛是加那利群岛最活跃的火山区之一,过去一星期活动十分频繁。这座火山最近一次大规模喷发是在1971年,当时有一名男子在熔岩流旁拍照时意外死亡。
Volcano lava destroys 320 buildings on Spanish island

The vast wall of molten lava creeping down the slopes of Spain’s La Palma island has destroyed 320 buildings and over 154 hectares of land, Europe’s volcano observatory said Wednesday.
The property damage figure was twice that given 24 hours ago by Copernicus, which uses sky radar imagery to monitor the extent of lava coverage and posted the update on Twitter.
The Cumbre Vieja volcano, which erupted on Sunday, straddles a ridge in the south of La Palma, one of seven islands that make up the Canary Islands, Spain’s Atlantic archipelago which lies off the coast of Morocco.
Experts are expecting the scale of damages to rise in the coming hours as the slow-moving but unstoppable mass of white-hot rock, slides towards the island’s western coast.
“In the last few hours it has slowed down a lot, it is now moving at 300 metres (984 feet) an hour, maybe less, because it is reaching a very flat area but it is gaining height,” David Calvo, an expert with the Involcan volcanology institute, told AFPTV.
“There are areas where it is already 15 metres thick.”
If the lava — which has a temperature of 1,100 degrees Celsius (2,012 degrees Fahrenheit) — continues to move at the same pace, it will reach the sea later on Wednesday or possibly Thursday, he said, warning it would have an explosive effect.
“There will be a huge battle between the water and the lava. With those contrasting temperatures, it causes massive explosions and a fragmentation of the lava which shoots out like missiles.”
The eruption on this island of some 85,000 people, the first in 50 years, has forced some 6,000 people out of their homes, but so far nobody has been injured.
Involcan believes the eruption of La Cumbre Vieja could last “between 24 and 84 days”.
“Dealing with this crisis won’t end when the lava reaches the sea,” Prime Minister Pedro Sanchez said on Tuesday.
“It will end when we’ve managed to rebuild everything the volcano has destroyed and will destroy.”
