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
Fonoifua island #Tonga after the #tsunami. Maybe some damage on the east side of that beach, but much less obvious here than elsewhere. Larger Vegetation near shore untouched, all the major structures still intact.
I take that back... looks like the lower elevation structures taken out by a #tsunami there on Fonoifua when you view before/after in Google Earth at an angle. :-(
Before/after in Google Earth of Fonoifua #Tonga. I now think hit by the #tsunami with quite a bit of debris scattering.
It appears they had a delivery of water on January 14th (not sure what the issue was with their normal supply) -- hopefully some of that water survived the inundation
The water was delivered to this building (school? community center?), at 19ft ASL. You can see the solar panels were destroyed, and the water tank pushed past the building by the #tsunami surge.
Here's that water tank, so clearly a big enough surge to push a heavy tank (presumably empty since they are getting deliveries of water) 130 feet. #Fonoifua
#Fonoifua Tsunami likely took out their new(er) solar panel array, which appears to be against the ocean. The foundation of a home (presumably destroyed in an earlier disaster) plus this cement planter obvious.

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 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.
