High-impact eruption at Semeru volcano, Indonesia

Ash rises to 14 km (46 000 feet) above sea level.

Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 46000 ft (14000 m) altitude or flight level 460 .

  1. Calling this thing a “High Impact Eruption” is almost beyond dumb as an explanation, because 99.9% of everyone immediately thinks it relates to a collision, i.e. Impact, of a large object to the planet, from space. Now, if using “geological”, or “world” impact, the prefix would explain things better.

  2. I mentioned this two days ago. It will have the sky’s purple tint at sunset again. For a while. After so many large eruptions in the past year, it has to have a cumulative effect on our temperatures . NEXT WINTER COULD BE INTERESTING. THIS SUMMER COULD BE COOLER. WITH THE SUN STILL IN A LULL, THE PERFECT STORM IS BREWING…

    • This is exactly what I’m thinking as temperatures drop from the four day heat wave to 12 C in montreal today. The water cycles are established a new meteorological order as the volume of ice water melting at once is just that much higher than previously as it was thin ice over a large surface area and all the fresh water will not sink easily. The water in the St.Lawrence was ice cold while the air was burning hot. This has never been the case before. I love swimming in cold water and temperature was unbearably cold. Then a whale swam into the river all the way to the city! I think an ice age could be our best most efficient chance to renew the planet’s soil and air though.

  3. reading where one of the hawaiian volcanos is forming a big lake, with concern about the mess if it should erupt..would think concernis due to them knowing that magma may be building or close to the surface
    like white island in NZ that killed so many earlier in the yr with little warning(and what was given was ignored)

  4. The same powers that are abusing our rights to “protect” us from COVID are hoping that a major natural disaster takes place so they can expand their controls even further.

    When things get very cold, they will round up all the climate change critics and blame them for the climate not warming as predicted.

  5. Hi Robert, ta for the heads up, won’t find that news anywhere, plus the dust might even block sun here this coming 2020 Aussie winter. Last year dust from Uluwun volcano in Papua was making high flat clouds which literally gave a veil to stop the sun at full bore. Interesting to watch, I think I will have to go through sky photos from Brisbane one day and do a time line of solar inactivity from 2106 when I first started seeing ice crystal clouds, I take heaps of sky photos, lots of nice ones, can’t help myself. That Semura eruption is very high and is enough to make purple sunsets and sunrises as it is going up to the stratosphere. I swear there have been some purple sunsets from thin flat clouds high up in Brisbane a month or so ago and there are no fires right now. Last year you can find stories and pictures from people all over the Northern Hemisphere who were seeing purple skies and right up to December. I even saw a dust storm hit Brighton in August 2019 and wondered if it was sandstorm from the Sahara or the Kuril Volcano. More likely a sandstorm, later in Jan 2020 and Feb 2020 sandstorms from the Sahara went over Europe. . If Semura effects us I’ll definitely show pictures from here one day.
    Fantastic photo last year’s eruption here which hits the roof of space.

    ‘Since ash contains sharp fragments of rock and volcanic glass, it poses a serious hazard to aircraft. The Tokyo and Anchorage Volcanic Ash Advisory Centers have been tracking the plume closely and have issued several notes to aviators indicating that ash had reached an altitude of 13 kilometers (8 miles). Meanwhile, data from the CALIPSO satellite indicate that parts of the plume may have reached 17 kilometers (10 miles).

    In addition to tracking ash, satellite sensors can also track the movements of volcanic gases. In this case, Raikoke produced a concentrated plume of sulfur dioxide (SO2) that separated from the ash and swirled throughout the North Pacific as the plume interacted with the storm.

    “Radiosonde data from the region indicate a tropopause altitude of about 11 kilometers, so altitudes of 13 to 17 kilometers suggest that the eruption cloud is mostly in the stratosphere,” said Carn. “The persistence of large SO2 amounts over the last two days also indicates stratospheric injection.” June 2019 Raikoke Erupts https://earthobservatory.nasa.gov/images/145226/raikoke-erupts

  6. Seems like there is a definite uptick in volcanic activity occurring and more cloud cover! Is anyone monitoring particulate matter in the atmosphere that can provide definite any evidence?

    • JNS,

      When a get a chance look up condensation nuclei. Gonna get REAL interesting here soon.
