Radiative forcing by super-volcano eruptions
We investigate the climatic effects of volcanic eruptions spanning from Mt.\ Pinatubo-sized events to super-volcanoes. The study is based on ensemble simulations in the Community Earth System Model Version 2 (CESM2) climate model using the Whole Atmosphere Community Climate Model Version 6 (WACCM6) atmosphere model. Our analysis focuses on the impact of different \ce{SO2}-amount injections on stratospheric aerosol optical depth (AOD), effective radiative forcing (RF), and global temperature ano…

Good Morning #Canada
It's Sunday so a nice relaxing read with a coffee is in order. And this article about one of Canada’s most dangerous volcanoes is perfect... unless of course you live in the shadow of Mount Meager. The Mount Meager massif is a group of volcanic peaks in the Pacific Ranges of the Coast Mountains in southwestern BC. It last erupted some 2,400 years ago but recent volcanic a…

Something melted a hole through the glacier above the Mount Meager Volcano in 2016. A perilous expedition ventured deep inside the cave to find out, did the volcano wake up?

Efficient Enumeration of Recursive Plans in Transformation-based Query Optimizers
Query optimizers built on the transformation-based Volcano/Cascades framework are used in many database systems. Transformations proposed earlier on the logical query dag (LQDAG) data structure, which is key in such a framework, focus only on recursion-free queries. In this paper, we propose the recursive logical query dag (RLQDAG) which extends the LQDAG with the ability to capture and transform recursive queries, leveraging recent developments in recursive relational algebra. Specifically, th…

Looks like the #Ruang #volcano put up 0.25 (more likely)-0.5 Tg of SO2 15-20 km up in the stratosphere. (1991 Pinatubo was more like 18Tg SO2 for scale)
H/T Ghassan Taha and Simon Carn for these images
Not enough to cool temperatures down much at all, but interesting as many scientists are discussing the Hunga Tonga eruption this week (which injected a similar amount of SO2 but ALOT ALOT more water).

Icelandic Volcano erupts for fourth time in three months
Icelandic police have declared a state of emergency as lava spewed from a new volcanic fissure on the #Reykjanes #peninsula, the fourth eruption to hit the area since December.
A volcanic eruption “started between stora Skogfell and Hagafell”, said …

Remember back in 2010 when a volcanic eruption in Iceland disrupted transatlantic flights?
Currently, there is no risk of this disruption.
However, I’ve often pondered what would happen if there was a major European tech conference with a heavy North American attendee profile (cough :KubeCon: cough) and a similar situation occurred again. Would everyone stay put? Fly the “wrong” direction to get home?
I don’t know why I think about such things.

Iceland volcano erupts again near Grindavik, Blue Lagoon evacuated
A volcano in Iceland has erupted for the fourth time in three months, sending orange jets of lava into the night sky. Iceland’s Meteorological Office said the eruption Saturday evening opened a fissure in the earth about two miles long between Stóra-Skógfell and Hagafell mountains on the Reykjanes Peninsula. Hundreds of people have been evacuated from the Blue Lagoon thermal spa, one of Iceland’s top tourist attractions. The eruption site is a few miles northeast of Grindavik, a coastal t…

Deep Learning Forecasts Caldera Collapse Events at Kīlauea Volcano
During the three month long eruption of Kīlauea volcano, Hawaii in 2018, the pre-existing summit caldera collapsed in over 60 quasi-periodic failure events. The last 40 of these events, which generated Mw >5 very long period (VLP) earthquakes, had inter-event times between 0.8 - 2.2 days. These failure events offer a unique dataset for testing methods for predicting earthquake recurrence based on locally recorded GPS, tilt, and seismicity data. In this work, we train a deep learning graph neur…

“A team of student researchers has made a giant contribution to solving one of the biggest mysteries in archaeology by revealing the content of Greek writing inside a charred scroll buried 2,000 years ago by the eruption of Mount Vesuvius. The winners of a contest called the Vesuvius Challenge trained their machine-learning algorithms on scans of the rolled-up papyrus, unveiling a previously unknown philosophical work that discusses senses and pleasure.”

ukpol rwanda
Tonight the MPs will debate and vote upon a law to send refugees to Rwanda. Not people who they claim aren't refugees. Just actual refugees.
They sold it as "for processing there" initially, but in fact it's just send them there never to return.
At a cost of over a million pounds per refugee.
Since the courts found that Rwanda might not be safe, the law they will debate declares that it is in fact safe. Even if a civil war breaks out tomorrow, even if a volcano turns the whole country into a lava-floor, it'll still be legally safe according to our MPs.
They seem to think that the Parliament is some kind of supreme body able to define and enforce the nature of truth, rather than being just one of many institutions of state which are set up to compete with checks and balances in order to prevent tyranny.
I can't think of a more obvious demonstration that the house has lots it's wits entirely and has become crazed with power.
They think they can legislate truth, and should have no legal restraints upon them.
You'd hope an election soon will remove them, but the opposition, Labour, are fine with it, so long as it doesn't include our military collaborators. They have an amendment saying it's fine to send everyone I guess, except not those who collaborated with our military.
What a broken country. We need to disband Westminster, really, it's become corrupt beyond redemption.
