Volcano, quakes spark fears on Indonesia's Sumatra （ロイター）

PADANG, Indonesia, April 12 (Reuters) - A volcano on Indonesia's Sumatra island erupted on Tuesday sending hot ash high into the air and forcing the evacuation of hundreds of villagers, officials said.
The eruption was accompanied by a string of moderate earthquakes that rattled towns in Sumatra, which is still recovering from a massive Dec. 26 quake and tsunami that killed nearly 130,000 people on its northern end.
Scientists have warned of increased seismic activity in Indonesia following the magnitude 9 quake in December as the plates that make up the earth's crust adjust.
Officials said hot ash and thick smoke spewed out of Mt Talang, which lies near the west coast city of Padang, 938 km (582 miles) northwest of Jakarta, near the epicentre of four moderate quakes on Tuesday.
An official in the nearby town of Solok said hundreds of villagers living on the slopes of the 2,690 metre (9,825 ft) volcano had been evacuated so far.
"Residents within the radius of 3-4 km (2 miles) have been evacuated to a sports stadium in a neighbouring town," Elvi Sahlan, Solok deputy mayor, told Reuters by telephone.
"The quakes and aftershocks can accelerate volcanic activity ... The quakes don't cause the eruption, but they add energy to it," Budi Waluyo, chief officer at the meteorology and geophysics office in Jakarta, told Reuters.
The volcanic activity and quakes sparked panic among residents of Padang, a city of nearly one million people, which was hit last Sunday by a quake measuring 6.8 on the Richter scale.
Officials said of the quakes recorded on Tuesday the biggest measured 5.8 on the Richter scale, with an epicentre around 150 km (90 miles) southwest of Padang.
"The four quakes we recorded overnight more or less had their epicentres in the same area in the ocean," Rasidi, another official at the geophysics and meteorology office in Jakarta.
Some Padang residents fled to higher ground, fearing a tsunami, witnesses said.
Indonesia has been hit by daily aftershocks since the quake on Dec. 26. A quake off Sumatra on March 28 is estimated to have killed up to 2,000, many on Nias island off Sumatra's west coast.
Indonesia is a vast archipelago of some 17,000 islands that lies along the geologically active "Pacific Ring of Fire" and has more than 100 active volcanoes.

インドネシア・スマトラ島で火山噴火、２万５千人が避難 （asahi.com）
2005年04月13日01時48分
インドネシア・スマトラ島中部で１２日、タラン山（標高２８９６メートル）が噴火した。国営アンタラ通信によると、夜明け前に火山灰を噴き出し始め、同日午後７時前までに計３回の爆発があった。同通信は同夜、地元当局の話として、２万５０００人が避難していると伝えた。
タラン山は、西スマトラ州の州都パダンの東約４０キロにある。火山灰は風に運ばれ、周辺地域に強いガス臭が広がっている。タラン山は１９世紀に少なくとも４回噴火。近年も１９８１年、０１年、０３年に小さな噴火があったという。
パダン沖では１０日にマグニチュード６．７の地震が発生し、パニックを起こした住民が高台に殺到したばかり。最近の巨大地震との関連について「地殻活動として、つながりがあるのではないか」とみるインドネシアの学者もいる。
