Intense explosions at Sakurajima, Japan


Intense explosions accompanied by volcanic ash which is falling on nearby communities are continually observed at Japanese Sakurajima volcano.

The Tokyo VAAC reported an explosion at 03:38 UTC today sent volcanic ash up to 2.7 km. Explosion at 09:41 UTC sent ash up 3 km.

Thanks to James Reynolds, founder of Earth Uncut TV, and Robert Speta of the WestPacWx we can get a better picture of what it's like being near Sakurajima today.

JMA reported that three explosions from Showa Crater at Aira Caldera’s Sakurajima volcano ejected tephra as far as 800 m during January 19 – 23.

Incandescence from the crater was visible at night on January 22. Inflation continued to be detected.

Tokyo VAAC reported that on January 23 plumes rose to altitudes of 3 – 4.9 km a.s.l. and drifted SE. During January 24 – 27 plumes rose to altitudes of 1.8 – 3 km a.s.l. and drifted SE, E, NE, and N.

Geologic summary

The Aira caldera in the northern half of Kagoshima Bay contains the post-caldera Sakurajima volcano, one of Japan's most active. Eruption of the voluminous Ito pyroclastic flow accompanied formation of the 17 x 23 km caldera about 22,000 years ago. The smaller Wakamiko caldera was formed during the early Holocene in the NE corner of the Aira caldera, along with several post-caldera cones.

The construction of Sakurajima began about 13,000 years ago on the southern rim of Aira caldera and built an island that was finally joined to the Osumi Peninsula during the major explosive and effusive eruption of 1914.

Activity at the Kitadake summit cone ended about 4850 years ago, after which eruptions took place at Minamidake.

Frequent historical eruptions, recorded since the 8th century, have deposited ash on Kagoshima, one of Kyushu's largest cities, located across Kagoshima Bay only 8 km from the summit. The largest historical eruption took place during 1471-76.

  1. Update: EQ cluster in Alaska ongoing since BEFORE 1/30. But one canNOT see until all has passed.

    There will be a brief silence as he “recharges”…
    Then, you don’t know until all has passed, right before you are about to make a “prediction” based on what you have seen. This avoids” he will make a fool out of you very quickly”

    “Verily I say unto you, that this generation shall not pass, till all these things be done.” Mark 13 30

    To scientists, this generation means another billions (one 90s–>one 9, one 19…) of years later.
    I watched carefully the behaviors of baby boomers aka “snow birds” for a while. “Beneath” or “inside” the golf swing, is a pile of garbage. George Carlin’s “garbage in, garbage out” is the most applicable. Of course, no two things alike. There are always good individuals like lotus out of the dirt, who have got the “memo”.

    3 11 2011 EQ, Tsunami, Fukashima nuclear plant, right after you thought you had seen all with the 2009 financial Tsunami, EQ, derivative ponzi gamma ray outburst.

  2. I’m pretty sure the people of Pompeii also thought the nearby erupting volcano was fun to observe, but sadly ignored the much larger and grave implications…Then again Fukushima doesn’t seem to concern anyone, so I guess it’s all a moot point!

  3. You should have been watching the sequence in the last 2or 3 days. You will continue to see the action for about 1 more day. It starts BFORE the “6.1” in FIJI right around the gut of the earth. Then his fastball starts to climb the ladder: The Northern Cal. cluster, then the UK, not a place well known for EQ; then Redmond, WA, France, Kansas-OKlahoma. Then the 2nd pitch starts BEFORE “6.0” in Vanuatu; Then the 3rd pitch climbs the ladder again– a big fastball @ Sakurajima, so big that it causes lightning.

    The best past is nobody knows when the 1st or the 3rd pitch starts and ends; No one can sense the separation between any of his 2 pitches. One can only see until ALL has passed.

    No wonder why scientists always strike out when they try to swing at it. I have been fascinated by the pitcher and stopped paying attention to the hitters for a long time. The downside of “known” is it becomes boring very quickly… Why do you want to swing at it in the first place? What is wrong with “doing nothing”?
