Very strong eruption of Mount Shindake, Japan – injuries reported


A very strong eruption of Japanese Mount Shindake (Kuchinoerabujima group) started at 01:00 UTC on May 29, 2015. At 02:26 UTC, Tokyo VAAC reported ash plume reached an estimated altitude of 10.9 km (36 000 feet). 

JMA issued highest alert level (5/5) and reported that pyroclastic flows from the volcano had reached the shore to the northwest.

The municipal government has issued an evacuation order to all of the island's 137 residents.

JMA warns there is a risk of a second eruption and associated pyroclastic flows. "So far, the pyroclastic flows had not struck the populated Maeda district."

Two people have been reported injured, presumably burnt by pyroclastic surge, and were flown to a hospital in Yakushima island, Volcano Discovery reports. "So far, it is not clear whether the eruption is a large-scale phreatic (steam-explosion driven) event or caused by new magma. Ash analysis should bring light into this soon."

At 06:30 UTC, Tokyo VAAC reported volcanic ash emissions are still in progress.

Previous eruption of Mount Shindake occurred on August 3, 2014 (VEI 1), after 34 years of sleep (VEI 2 on September 28, 1980).

Shindake's eruption in 1841 destroyed villages and claimed many lives, while a series of eruptions from late 1933 to early 1934 left eight people dead and 26 injured, according to an article published in Japan Times today… 

Experts had recorded unusual activity for about a decade leading up to last year’s eruption, and the latest blast could be a relatively large, prolonged one. – Associate Professor Ryusuke Imura of Kagoshima University.

Geological background

A group of young stratovolcanoes forms the eastern end of the irregularly shaped island of Kuchinoerabujima in the northern Ryukyus, 15 km west of Yakushima. Furutake, Shintake, and Noike were erupted from south to north, respectively, to form a composite cone that is parallel to the trend of the Ryukyu Islands. The highest peak, Furutake, reaches only 657 m above sea level. The youngest cone, 640-m-high Shintake, was formed after the NW side of Furutake was breached by an explosion.

All historical eruptions have occurred from Shintake, although a lava flow from the S flank of Furutake that reached the coast has a very fresh morphology. Frequent explosive eruptions have taken place from Shintake since 1840; the largest of these was in December 1933. Several villages on the 4 x 12 km island are located within a few kilometers of the active crater and have suffered damage from eruptions. (GVP)

  1. Actually the extreme number of volcanic eruptions right now is similar to what has happened in history preceding the mini ice age. Large amounts of S02 in the atmosphere usually lead to global cooling… or so I’ve read.

  2. Since 8 May of current year 2015 , this writer has been astrologically predicting world-wide that ” bad smell” or ” foul smell” substance like oil spill and volcano eruption could occur at vulnerable places round the globe during a period of one month and 20 days from 10 June 2015 to 30 July 2015. Already oil spill in California surfaced recently around 20 May 2015 spreading foul smell on the eve of the predicted period. Obviously foul smell or uncomfortable smell due to oil spill is likely to percolate to the predicted period. Similarly , the volcano eruption in Japan on 29 May is likely to generate foul or uncomfortable smell spilling over to predicted period. Just thought readers may like to know nearly accurate uses of astrology in relation to global affairs.

  3. This volcano will definitely effect the weather. It put the ash cloud above 10 KM. That’s well into the jet stream.

    The extreme number of volcanic eruptions – from all over the world – will definitely check any human activity in global warming.
