One of the world’s most active volcanoes showed its ugly
side this weekend, erupting and producing an ash cloud that spread out across
one southern Japanese city.
Sakurajima, a volcano that sits in the background of the southern Japanese city of Kagoshima and is known for producing hundreds of small explosions per year, erupted Sunday in one of the volcano’s largest explosions in decades and perhaps the largest since an eruption in 1914, burying village homes in feet of ash.
The plume from Sunday’s eruption reached 16,500 feet (more
than 3 miles) before settling down over homes and businesses in Kagoshima and
surrounding areas. The ash caused poor visibility and train delays in the city
that sits just 5 miles east of the summit of Sakurajima. Residents who ventured
outside were forced to wear dust masks to keep from inhaling deadly volcanic
glass shards produced from explosive expansion of bubbles in erupting magma.
Some evidence from a YouTube video of the eruption shows
what might be small pyroclastic flows generated from the explosion as well.
On Monday, as the dust and ash settled, residents of the
southern city were out clearing ash from their cars and the streets. There is,
as yet, no word on what caused this larger-than-normal eruption, but some
believe there was a collapse in the Showa crater or perhaps some gas-charged
magma entered into the upper chamber.
The Associated Press reported a lava flow had also raced
more than a half-mile down the mountainside, but later reports refuted that
evidence. Still, this was the region’s largest eruption in decades and the
500th eruption this year alone.
No deaths or injuries have been reported with this latest explosion on Sakurajima.
“The smoke was a bit dramatic, but we are kind of used to
it,” a city official who requested anonymity told the Associated Press.
The Japan Meteorological Agency said there are no signs
Sakurajima will produce an even larger eruption but maintained similar activity
may continue. It had put up a warning people should not venture near the
volcano for at least the time being.
Japan sits on the Pacific “Ring of Fire,” a region that encircles nearly the whole of the Pacific Ocean and contains thousands of active volcanoes. The most recent activity has been observed in Alaska where a trio of “Ring of Fire” volcanoes – Cleveland, Pavlof and Veniaminof – has been showing their fiery side as of late.

Veniaminof, an 8225-foot-high volcano that sits on the
Alaskan Peninsula, became more active earlier this summer and is currently
under a code “orange,” according to the Alaska Volcano Observatory, which is
operated by the USGS. That volcano has continued to produce elevated,
sustained, seismic tremor levels and is being continuously monitored.
