#Chornobyl nuclear power plant taken via Sentinel-2 #satellite at 2022-03-08 09:06:34 UTC (about 15 hours ago).
Can't tell what is different post-invasion (aside from the layer of snow. ps. don't eat the now mildly radioactive snow).
Radiation sensors there apparently back on the grid. Not great, not terrible.
EPA says 2,000 nSv/h (the unit measure on that map) is what you get on an airplane. epa.gov/radnet/about-e…

Random thoughts on what cities should (but won't) do to transition out of a #gasoline dependent world. 1. separated bike lanes everywhere, particularly in working class neighborhoods that already heavily bicycle/pedestrian. Image
2. Bicycle racks at local stores and shopping centers. At least in my suburban area, even if you bicycle there, you can't lock up your bicycle anywhere! Image
3. Removing/repealing bicycle unfriendly laws, which often are used more as pretext to snag people using bicycles for work, rather than pleasure. tampabay.com/news/publicsaf…

Flooding seen on the Sentinel-1 satellite images as well around the town of Demydiv #Ukraine
Around Irpin, not so much flood as a full river where there have been ongoing battles between the Russians and Ukrainians. It would limit you to bridges. Sentinel-1 #satellite.
Stuff (probably, tanks/APCs/armor) burning on either side of the river near Moshchun. Image

If you think gas and energy prices are bad now, just wait as the climate crisis continues to take a toll on infrastructure (wildfires, floods, hurricanes, wind). Pumping more gas is only a temporary pricing fix, but it's a long term accelerator creating more issues.
Things we can do now: 1. decentralize to more resilient power (rooftop solar, batteries, microgrids) 2. decarbonize (wind, solar, geothermal) 3. Less individual transport, more bicycling/walking/mass transit first, EVs if you can, hybrid where necessary. 4. lots of disaster prep.
ps. I'm chuckling at all the folks commenting on "that's so dark" or "why the depressing content"... you must have missed reading any of the posts on this account through the last two dozen disasters ;-)

Mango Island #Tonga via Airbus SPOT imagery 1/16/22. Unfortunately the inhabited part of the island obscured by clouds. It appears either survivors or debris in a spot not normally occupied by people on lower right.
Reference image from 1/14/22 of Mango Island, you'll notice the bright spot visible in the other imaging not present. I suspect survivors of the tsunami put up some kind of shelter up at the high point of the island. Tent, leanto or stretcher. Looks like at least 5-6 people too
Tough to tell 100% but I would put money on these being people around a tent or some kind of temporary structure. #MangoIsland #Tonga #tsunami

Kanokupolu #Tonga taken yesterday, 1/16/22 via Airbus SPOT #satellite. Post volcano/tsunami. High resolution image, this looks to me to be ashfall.
#Tonga taken by Airbus SPOT on 1/16/22. This is (was?) Ha'atafu Beach and Haatafu Beach Resort, but it seems to me that there are structures missing on this side (the resort appears to me to be missing, or extremely covered with ash). Possible tsunami scouring on the beach.
Reference image in Google vs. this acquisition -- you can see the big building on the top right in both images, but none of the structures you'd expect at Ha'atafu Beach, Nuku'alofa itself. #tonga #tsunami #volcano
