Volcanoes

Generally an unmoderated forum for discussion of pretty much any topic. The focus however, is usually politics.

Volcanoes

Unread post by Vrede too »

Volcanoes have been discussed in the Can't make this (stuff) up, Traveling and Fire/EMS/ERs/disasters, etc. threads, but they don't necessarily fit in them, so new thread.

This is either the same crater that erupted in March, 2021 or is near it.

Volcano ERUPTS in Iceland, spewing magma from 'heart-shaped crater'

Magma flows from a heart-shaped crater as lava spews from the volcano in Fagradalsfjall, Iceland, following an eruption from a new fissure on the Reykjanes Peninsula, around 35 miles from the capital city of Reykjavic, the eruption has been ongoing from the 3rd August 2022.

Cool.

Remember the 2010 Iceland eruption that interrupted air travel from Europe?

The worst of it was just for 6 days in April.

This is a composite map showing the position of the Icelandinc volcanic ash cloud that closed European air space in different days.

Imagine what a bigger, longer eruption would do.

IIRC, air travel was disrupted for more than six days.

:oops: I somewhat misread your Wiki link:
... The disruptions started over an initial period of six days in April 2010. Additional localised disruption continued into May 2010, and eruptive activity persisted until June 2010....
The map I posted covers 12 days, 14 April to 25 April.

There's a separate webpage!
Air travel disruption after the 2010 Eyjafjallajökull eruption

... After an initial uninterrupted shutdown over much of northern Europe from 15 to 23 April, airspace was closed intermittently in different parts of Europe in the following weeks, as the path of the ash cloud was tracked. The ash cloud caused further disruptions to air travel operations in Scotland and Ireland on 4 and 5 May and in Spain, Portugal, northern Italy, Austria, and southern Germany on 9 May. Irish and UK airspace closed again on 16 May and reopened on 17 May....

Tonga eruption was so intense, it caused the atmosphere to ring like a bell

The Hunga Tonga-Hunga Ha'apai eruption reached an explosive crescendo on Jan. 15, 2022. Its rapid release of energy powered an ocean tsunami that caused damage as far away as the U.S. West Coast, but it also generated pressure waves in the atmosphere that quickly spread around the world.

The atmospheric wave pattern close to the eruption was quite complicated, but thousands of miles away it appeared as an isolated wave front traveling horizontally at over 650 miles an hour as it spread outward.

NASA’s James Garvin, chief scientist at the Goddard Space Flight Center, told NPR the space agency estimated the blast was around 10 megatons of TNT equivalent, about 500 times as powerful as the bomb dropped on Hiroshima, Japan, during World Word II. From satellites watching with infrared sensors above, the wave looked like a ripple produced by dropping a stone in a pond.

Image
Satellite infrared observations captured the pulse propagating around the world.

... Online, people followed the progress of the pulse in real time as observers posted their barometric observations to social media. The wave propagated around the whole world and back in about 35 hours....

This eruption was so powerful it caused the atmosphere to ring like a bell, though at a frequency too low to hear. It’s a phenomenon first theorized over 200 years ago....

It's the 16th, didn't this happen on the 15th?

I posted the video link last May. The Hunga Tonga-Hunga Ha'apai eruption was Jan 15, 2022.

I posted the January 14, 2023 article and gif because of the new info about the pressure waves in the atmosphere.

I have driven this road to the top, the Johnson Ridge Observatory.:
Landslide near Mount St. Helens takes out parts of Highway 504

I have driven up the slope of Sicily's Mount Etna and have seen magma glow there, but did not hike or summit, and it wasn't like this:
Etna Volcano Eruption, May 18, 2022 – Drone

I summited 17,802 ft Popocatépetl twice in the 1980s. It's been active since 1994. "Ever since then the mountain has been closed to climbing."

Two supervolcanoes, a world apart, have the attention of scientists

Two long-dormant “supervolcanoes” on two separate continents appear to be stirring to life. Well, maybe.

In recent months, more than a thousand minor earthquakes have rattled the area around the Campi Flegrei volcano in southern Italy, stoking fears that it may soon erupt again after nearly five centuries. Some 6,000 miles away, scientists have for decades recorded similarly small earthquakes and instances of ground deformation at the Long Valley Caldera, a volcano in eastern California that sits adjacent to Mammoth Mountain.
Directly east of the Bay Area on the NV border.

The good news is that the first to go will be Solar and then Useless.

11 climbers killed, 12 missing following Indonesian volcano eruption

Eleven climbers have died and another dozen are missing in Indonesia following the eruption of a highly active volcano in the province of West Sumatra, officials told CNN on Monday.

Located on the Pacific Ring of Fire, Indonesia has 127 active volcanos – more volcanoes than anywhere else in the world – and Mount Marapi is among the country’s most active....
:shock: :cry: The article doesn't say so but I would guess a pyroclastic flow for so many to have been killed and injured. A younger, volcano-obsessed me might have been among that group had I made it to Sumatra :think:
