Kirishima in Japan Erupts for the First Time Since 2011

For the first time given Sep 2011, Kirishima in Japan has started erupting. On the morning of Oct 11, new charcoal emissions began from the Shinmoe-dake cone on the large, formidable volcano on the north finish of Kagoshima Bay. The tear have been comparatively tiny ash-and-gas plumes that reached reduction than 1 kilometer (~3,200 feet) over the volcano and widespread shards of volcanic potion (aka ash) opposite the area. These new explosions have promoted the Japanese Meteorological Agency (JMA) to lift the warning standing to Level 3 and announce an ostracism section around the active vent. The plume from the tear was clearly seen on Terra MODIS picture (below) taken on Oct 11 (Universal time, so Oct 12 local).

The tear at Kirishima has been considerable in the transparent weather. Thus far, only charcoal has been seen erupting from the Shimmoe-dake cone, so there is no justification that new magma has reached the surface as the charcoal was likely generated from pulverizing old, cold lava in the lava architecture in the crater. A tiny trembler swarm started at Kirishima on Oct 5, heading JMA volcanologists to consider that an tear could be in the cards.

Film builder James Reynolds was on site at Kirishima for the tear on Oct 12 and got some thespian drone footage of the tear (note: all taken from outward the ostracism zone).

Two things that really mount out to me in the footage: (1) the volcano’s bark — you can really hear that low, growling sound of the charcoal emissions from the vent and (2) the pulsing inlet of the eruption, as charcoal and prohibited volcanic gases issue from the vent. You can also see how excellent the charcoal looks in that has depressed inside the crater, which reminds me of eruptions where mostly old volcanic materials is being pulverized. Some other fumaroles (gas vents) can be seen to the left of vent in the footage as well. The charcoal fast loses irresolution and falls to the ground, showing there isn’t a lot of “oomph” behind the tear at this point. Looking at images taken Oct 11 (below), the very active steam emissions in the void misuse a lot of feverishness under the old lava dome.

Now, it is unfit to contend where this tear is going. If new magma is found in the ash, then likely Kirishima is entering another eruptive proviso like we saw in 2011, where blasts went on for 9 months. However, if this is merely driven by steam and feverishness in the crater, then maybe it competence be a passing moment.

If you wish to watch the tear live, there are copiousness of webcams forked at the volcano. Right now (October 12), there isn’t much going on at the volcano.

Few other pieces of volcano news from elsewhere:

We speak about a plume that’s a few hundred meters at Kirishima, but Shiveluch in Kamchatka constructed a 10+ kilometer (32,800 feet) plume on Oct 11. Thanks to its remote plcae and rather common occurrence, eruptions like these at Shiveluch frequency make the news anywhere.

Meanwhile, two volcanoes that haven’t erupted in decades saw tiny trembler swarms. Cumbre Vieja on La Palma in the Canary Islands saw its first trembler swarm in many years, with over 50 earthquakes low under the island over a 3 day period. The last tear at Cumbre Vieja was in 1971. Similarly, Oregon’s Mt. Hood has a tiny swarm started under the White River Valley nearby the Cascade volcano — a mark where swarms are common and may be related to faults that run nearby the volcano. Neither swarm suggests that possibly volcano is close to an eruption, but rather remind us that even still volcanoes can be nervous occasionally.
