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
#Tonga #volcano #tsunami Airbus SPOT imagery of Vakaloa Beach Resort on 1/16/22... which appears to have been wiped from the map. LDS ward at Ikalahi Rd and Hihifo Road seems intact, but ash covered.
So hard to tell what's going on here at the Vakaloa Beach Resort... maybe this is just completely covered in ash. You can see the outline of the wall on the left, and a line along the sand where the building is/was... could conceivably be completely covered in ash.
Atata Island #Tonga after the tsunami and volcano eruption. Airbus SPOT imaging on 1/16/22. This looks very grim. Largest structure in town survived, but awfully hard to conclude there was not catastrophic tsunami damage.
Atata Island #Tonga after the tsunami and volcano eruption. Airbus SPOT 1/16/22. Locatin of Royal Sunset Island Resort. You can see what looks like the larger structures still there on the tip of the island. Unclear how much standing though.
Interesting data--Vakaloa Resort apparently already suffered massive damage in 2020 from Cyclone Harold... unclear if they rebuilt it since then. So Google Maps may be obsolete as a comparison source.
Faa'amotu International Airport, terminal/hangar buildings taken between clouds on 1/16/22. Not much ash here (a little on the runway, but not much), you can see a few planes. #Tonga
Fua'amotu #Tonga taken yesterday 1/16/22 via Airbus SPOT. Looks like only minor ashfall on the south side of Nuku'alofa, based on the color of the roofs. Vegetation is still green. I suspect minimal damage on this part of the island.
Just to catch anyone from earlier in this thread, more imaging:

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

Tonga Navy appears to have just reached the island of #Nomuka
This ship (the only one transmitting satellite AIS data) came from Nuku'afola this morning, when officials said they would be sending the Tonga Navy to the outer islands.
Found this video I had missed earlier from this location (FB Live... shot just as the seas were retreating. Hope this person made it up a hill, what was coming as likely worse)

#Nomuka #Tonga via Sentinel-1 #satellite, before and after the #HungaTongaHungaHaapai volcano eruption.
This island south of Nomuka looks to have been inundated, based on Sentinel-1 radar image (darker areas = water).
Using a new feature of @sentinel_hub here's a sequence of SAR radar before/Sentinel-2 true color before/and then SAR radar after where you can see where the reflectivity of the land has changed to water.

Hunga-Tonga-Hunga-Ha'apai #volcano before/after the eruption. Sentinel-1 satellite (-20.48838, -175.28037)
Hunga-Tonga-Hunga-Ha'apai #volcano on the left, you can see the interference patterns on the waves from the tsunami impacts (another volcano on the right). The gob of stuff in the middle was not there before, maybe floating tephra or something else radar reflective.
No tracking details on these ships (premium satellite data) but there are a few fishing boats that got one heck of a wakeup call earlier. There's a few that were VERY close to the volcano. (60 miles away on open ocean).

#MarshallFire #Superior #Colorado Structure fire reported at 1119 W Enclave Cir. Quite a few other structures fires I have not posted, too many to track.
#MarshallFire #Superior #Colorado Hospital sounds like it may be evacuated, not sure which one.
