Well the sky was more orange than red today, but still spectacular.

Since the volcano eruption I have not been able to access the USGS earthquake page ?
I normally look at it a couple of times a day.

Anyone got any earth observation links that you check on regularly?


Cheers

We don't see the colours out here. I made a point of looking this morning, just grey cloud.

I haven't looked at USGS, I subscribe to quakes over 4.5 and no mention of tremors associated with the volcano.

I check Geoscience Australia
https://earthquakes.ga.gov.au/
if there's anything in our region

Something shows up just south of Tonga there.

Then there's John Seach with
http://volcanolive.com/news.html

That's all I have. Not very much.

EDIT.....
Just discovered this in my bookmarks
Smithsonian / USGS Weekly Volcanic Activity Report

There's a mention here for today Tuesday 18/1/2022. Check the archives on the right for 15/1 and see the eruption just on nightfall.

VOLCANIC SHOCKWAVE RIPPLES ACROSS NORTH AMERICA: If you have a backyard weather station, you might have detected this weekend's volcanic eruption near Tonga. The undersea blast hurled a plume of sulfurous ash all the way to the stratosphere. Satellite videos show an atmospheric shockwave expanding on all sides of the plume.

Astronomer Matt Penn and colleagues decided to investigate further. "We plotted the times of barometric pressure peaks from 150 backyard weather stations available on Weather Underground," he explains. This movie sequence shows the data they found:

"White dots mark the arrival of the shock wave during the five hour interval 11:30 UT to 16:30 UT," explains Penn. "There were some very large amplitude differences! We clearly saw that the wave was severely reduced by crossing the Rockies. I think it would be very interesting to look at a smaller region, measure amplitudes, and track the reduction as the wave moves from California through the Rockies and onto the Great Plains. There is a gold mine in the Weather Underground data set."

"We looked at only 150 sites," Penn continues. "There are thousands of sites that show the pressure wave and lots of cool science projects that could be done. I hope this inspires more people to take a look!"

Yeah thanks 28, I had lost that John Seach link.
Lots of cool stuff about the pressure wave, we could feel it and my mate and I
were talking about it more on Sunday, a unique experience.

I'm envious Bunyip. The Featherbeds stop everything.

I was in North West WA when Pinatubo went up. Fantastic sunsets. And in Darwin a bit later still spectacular.
