Indonesia Volcano Erupts; 3 Killed, 100K Evacuated

SUGIHWARAS, Indonesia February 13, 2014 (AP)
By NINIEK KARMINI Associated Press


A powerful volcanic eruption on Indonesia's most populous island blasted ash and debris 18 kilometers (12 miles) into the air Friday, killing three people and forcing authorities to evacuate more than 100,000 and close seven airports.


The eruption of Mount Kelud on Java island could be heard up to 200 kilometers (125 miles) away, Indonesia's disaster agency said.


"The eruption sounded like thousands of bombs exploding," Ratno Pramono, a 35-year-old farmer, said as he checked his property in the village of Sugihwaras, about 5 kilometers (3 miles) from the crater. "I thought doomsday was upon us. Women and children were screaming and crying."


Ash and grit fell to earth in towns and cities across the region, including Surabaya, Indonesia's second-largest city after Jakarta, with a population of about 3 million. It also fell farther afield in Yogyakarta, where motorists switched on headlights in daylight. Workers attempted to cover the famed ninth century Buddhist temple complex of Borobudur with plastic sheeting to protect it.


A 60-year-old woman and an 80-year-old man were killed in the village of Pandansari, about 7 kilometers (4 miles) from the mountain, when the roofs of their homes collapsed under the weight of the ash and volcanic debris, the disaster agency said. A 70-year-old man died after being hit by a collapsed wall while waiting to be evacuated from the same village, where the volcanic ash reached 20 centimeters (8 inches) deep in some places.


The large international airport in Surabaya and airports in the cities of Malang, Yogyakarta, Solo, Bandung, Semarang and Cilacap were closed due to reduced visibility and the dangers posed to aircraft engines by ash, Transport Ministry spokesman Bambang Ervan said. Virgin Australia said it canceled its Friday flights from Australia to several locations due to the eruption, including the resort islands of Bali in Indonesia and Phuket in Thailand.


The disaster agency said tremors were still wracking the volcano but that scientists didn't expect another major eruption. It said residents of all villages within 10 kilometers (6 miles) of Kelud — more than 100,000 people — had been evacuated to temporary shelters, but that some were returning to their homes to begin cleaning up.


The 1,731-meter (5,680-foot) -high mountain in eastern Java — Indonesia's most densely populated island and home to more than half of the country's 240 million people — had been rumbling for several weeks and was under close observation. The mountain is about 600 kilometers (375 miles) east of Jakarta, the capital.


As night fell, the volcano continued to rumble, spewing ash high into the air, though smaller amounts than earlier.


"It seems Kelud isn't finished yet," said Retno Dwiningtyas, a mother of three who was sitting in a government shelter watching television reports of her village showing crumpled roofs, farms and broken chairs blanketed with thick gray ash. "We are afraid for our cattle, our farm."


Muhammad Hendrasto, head of Indonesia's volcano monitoring agency, said the mountain erupted violently about 90 minutes after authorities raised its alert status to the highest level. The disaster agency said it had spewed millions of cubic meters of debris into the atmosphere.


Kediri, a normally bustling town about 30 kilometers (19 miles) from the mountain, was largely deserted as residents stayed indoors to avoid the choking ash.

那叫"火山雷",是火山劇烈噴發的火山灰摩擦放出大量電荷產生靜電自然現象。  發表於 2014-2-15 09:55
火山爆發有閃電很正常...  發表於 2014-2-15 09:30
火山煙柱裡出現閃電?乖乖,這啥情況?  發表於 2014-2-15 07:11

近期比較有名的是日本九州鹿兒島櫻島火山噴發,出現大規模火山雷的現象。

聲勢好驚人可以說是大地的咆嘯不過整體而言還算美觀。

typhoonman大那個一部份成因是『火山雷』沒錯但並不只是因為火山灰磨擦空氣的能量靜電喔,那個叫電離子藍色閃電部份是您所說火山灰磨擦空氣產生的靜電離子又稱閃電是無聲的。

有聲音的是等離子又稱作響雷的紅色燃燒電流一般存在於雷雲中,火山主要的響雷是來至於底曾氦氣與硫磺受高溫引爆後溶解岩層適放其中累積的物質能量燃燒產生閃電因為有火在引燃所以是紅色的。

火山周遭空氣中的靜電離子火山雷大多發生在火山灰高度的空中對地表引響時間跟程度都比較慢跟小,但岩表爆炸式的雷火電流卻是極高溫且為急性俱燃燒破壞性質的。

一般而言遇到這種帶電的火山噴發最好是能離多遠就多遠快跑就對了。

難民撤離情況:兩種口罩差很多,帶紗布口罩是想怎樣?火山灰含大量游離二氧化矽粉塵,顆粒的長相像迷你海膽,一吸進肺裡,就永遠卡在末梢,吸多了就是纏綿難癒的阻塞式肺炎。

印尼夷哇島的火山再度爆發希望他們那邊的居民能夠儘早避難。

火山爆發是在有活火山的國家無可避免的災難希望在噴發的當時能夠迅速的撤離,減少不必要的損失。
