No injuries reported, but communication is intermittent.

> There were no immediate reports of injuries or the extent of the damage because all internet connectivity with Tonga was lost at about 6:40 p.m. local time — about 10 minutes after problems began, said Doug Madory, director of internet analysis for the network intelligence firm Kentik.

> Tonga gets its internet via an undersea cable from Suva, Fiji, which presumably was damaged. The company that manages that connection, Southern Cross Cable Network, could not immediately be reached for comment.

There are social media posts of the tsunami though which I believe are from Tonga. So folks at the shoreline were presumably fine enough to record and post video somehow.

I’d be worried about anyone on an airplane near there, but I guess it’s not a highly trafficked route.

I was curious whether Fua'amotu International Airport is a stop on flights going elsewhere but I wasn't able to come up with a good search. It sounds like it could be:

"The air field was constructed by Seabees of the 1st Construction Battalion with assistance and labor of the U. S. Army 147th Infantry Regiment. It was intended as a World War II heavy bomber field, and had three coral-surfaced runways. In the late 1970s, it was expanded to permit jet aircraft to use the runways. Fuaʻamotu is now suitable for up to Boeing 767 size aircraft, but remains closed to larger jets (e.g. Boeing 747s)."

Today's aircraft can easily handle transpacific flights, and Tonga is in the Southern Hemisphere close to the equator so even Southern Hemisphere flights would likely avoid it.

It's basically just Australia and New Zealand to Hawaii and North America, and Pacific Islands east of Tonga. As well as any inter-Oceanic flights that happen to pass it.

I wonder how these social media posts were being uploaded due to a loss of internet connectivity. Satellite internet, or has internet been restored already?

If the undersea cable was damaged I doubt it was repaired that quickly. I’m guessing satellite Internet.

Last time the undersea fibre optic cables (international and local) were broken (2019-2020) [0] a Kacific [1] K-band satellite emergency link was installed for and by the Tonga ISP EziNet [2] and others.

(the 2019 break was caused by a Turkish oil tanker prematurely dropping anchor in a restricted zone [3])

"DS Venture Ltd (DSV) was the owner of the Duzgit Venture. On 20 January 2019, as the vessel approached the Port of Nuku'alofa, its starboard anchor and chain were prematurely released from their housing. As the anchor and chain were winched back in, they caught and damaged a cable. The cable was one of two undersea communications cables owned by Tonga Cable Ltd (TCL) connecting Nuku'alofa, Ha'apai, and Vava'u with Fiji. As a result of damage to the cable, Tonga was without cable telecommunications for almost three weeks. "
