马尼拉：菲律宾国家地震学办公室称，菲律宾最活跃的火山之一周五（10月30日）发生“中等强度爆炸式喷发”，喷出一股黑色火山灰柱直冲数千米高空，持续近六分钟。
MANILA: One of the Philippines' most active volcanoes fired a dark column of ash thousands of metres into the sky on Friday (Oct 30) in a "moderately explosive eruption" that lasted nearly six minutes, the state seismology office said.
目前尚无马荣火山周边城镇人员伤亡或财产损失的即时报告，但该国火山研究所已将警戒级别从2级上调至3级（该级别体系为0至5级），并呼吁疏散火山口方圆6公里内的居民。
There were no immediate reports of casualties or damage in towns and cities surrounding Mount Mayon, but the country's volcano institute raised the alert level from 2 to 3 on its 0-5 scale and called for evacuations within 6km of the crater.
菲律宾火山与地震学研究所发布公告称，3000米高的火山灰柱逐渐向西南方向飘散，覆盖附近人口稠密地区。
The 3,000m ash column gradually drifted southwest onto nearby population centres, the Philippine Institute of Volcanology and Seismology said in a bulletin.
该研究所称：“马荣火山正处于岩浆喷发的新阶段，熔岩流和危险的火山碎屑密度流（PDC）……在未来数天至数周内影响火山中上坡的可能性增加。”
"Mayon is in a new phase of magmatic eruption, with increased chances of lava flows and hazardous PDCs (pyroclastic density currents) ... affecting the upper to middle slopes of the volcano in the immediate days to weeks," it said.
该研究所敦促地方官员疏散火山口附近区域人员，理由是“存在火山碎屑密度流、熔岩流、落石和其他火山灾害的危险”，并建议飞机避免靠近该火山飞行。
It urged local officials to evacuate areas near the crater "due to the danger of PDCs, lava flows, rockfalls and other volcanic hazards", with planes also advised to avoid flying close to the mountain.
海拔2462米的马荣火山呈近乎完美的锥形，位于马尼拉东南约330公里处，是菲律宾今年活动水平升高的三座火山之一，不过并未发生大规模喷发。
The 2,462m Mayon, rising in a near-perfect cone about 330km southeast of Manila, is one of three Philippine volcanoes that have shown elevated levels of activity this year, though no major eruptions occurred.
2023年6月，居住在马荣火山低坡上的超过1.2万人被转移至疏散中心，以躲避火山口喷出的火山灰和有毒气体。
In June 2023, more than 12,000 people living on its lower slopes were moved to evacuation centres to protect them from ash and toxic gases spewing from its crater.
由于菲律宾地处太平洋“火环”之上，构造板块在此碰撞，地震和火山活动频发。
Earthquakes and volcanic activity are common in the Philippines due to its position on the Pacific "Ring of Fire", where tectonic plates collide.
菲律宾近几十年来最强烈的火山喷发是1991年的皮纳图博火山喷发，造成800多人死亡，产生的火山灰云飘散数千公里。
The country's most powerful eruption in recent decades was Mount Pinatubo in 1991, which killed more than 800 people and produced an ash cloud that travelled thousands of kilometres.
