Military flights sent to assess damage from Pacific volcano:
New Zealand and Australia were able to send military surveillance flights to Tonga on Monday to assess the damage a huge undersea volcanic eruption left in the Pacific island nation.
A towering ash cloud since Saturday's eruption had prevented earlier flights. New Zealand hopes to send essential supplies, including much-needed drinking water, on a military transport plane later Monday.
Communications with Tonga remained extremely limited. The company that owns the single underwater communications cable that connects the island nation to the rest of the world said it likely was severed in the eruption and repairs could take weeks.
The loss of the cable leaves most Tongans unable to use the internet or make phone calls abroad. Those that have managed to get messages out described their country as looking like a moonscape as they began cleaning up from the tsunami waves and volcanic ash fall.
Tsunami waves of about 80 centimeters (2.7 feet) crashed into Tonga's shoreline, and New Zealand Prime Minister Jacinda Ardern described damage to boats and coastal shops.
No casualties have been reported on Tonga, although there were still concerns about people on some of the smaller islands near the volcano. The tsunami waves crossed the Pacific, drowning two people in Peru and causing minor damage from New Zealand to Santa Cruz, California.
Scientists said they didn't think the eruption would have a significant impact on the Earth's climate.
Huge volcanic eruptions can sometimes cause temporary global cooling as sulfur dioxide is pumped into the stratosphere. But in the case of the Tonga eruption, initial satellite measurements indicated the amount of sulfur dioxide released would only have a tiny effect of perhaps 0.01 Celsius (0.02 Fahrenheit) global average cooling, said Alan Robock, a professor at Rutgers University.
Satellite images showed the spectacular undersea eruption Saturday evening, with a plume of ash, steam and gas rising like a giant mushroom above the South Pacific waters.
A sonic boom could be heard as far away as Alaska and sent pressure shockwaves around the planet twice, altering atmospheric pressure that may have briefly helped clear out the fog in Seattle, according to the National Weather Service. Large waves were detected as far as the Caribbean due to pressure changes generated by the eruption.

Usually this is where ham/amateur radio shines. But maybe there aren't any hams on Tonga?

Ham radios are not lovely, wonderful cell phones so they were recycled with all of the other old stuff. Recycling old stuff is good for the planet.

SDR doesn't solve the problem of needing transmission hardware. Low-power sub-Ghz seems to be more popular in the SDR space, probably because of crypto-stuff like Helium.

Can you exchange Bitcoin over ham radio? I'm aware of AMPRNet, and I suppose IPoAC could work if you had enough carrier pigeons around, but I wonder if you could actually exchange Bitcoin under current conditions on Tonga.

No. "Pecuniary interests" are forbidden by law.
It's very easy to do (I'd do QR codes over SSTV, rather than do brick-sized-dildo Internet protocols). But what would happen if every brain-wormed Internet cripple discovered a need to do it...
Amateur Radio is a privilege provided by Governments to the very fragile radio frequencies, with a history involving war, espionage, and anti-social behavior going back over a century. (When the Titanic sunk, Trolls were impersonating survivors.. A few years later, Licencing was introduced to have a framework for removing such operators from the air).
Also, the King of Tonga won't be very happy if you side-step his income from taxing remittances. (Family sending money 'home' is Tonga's greatest source of revenue-- it's too corrupt to have a healthy economy.)

Had not heard this before, just googled with no luck. Do you have a reference for these ~100 year old Trolls?

Thank you for the answer. Although my question was labelled as a troll, I was honestly curious about it.
Seems this isn't the place for honest curiosity anymore, so I shall desist from further inquiry.

If you figure about 1 ham radio operator per 10,000 people (which seems pretty typical among countries that allow them), that means there are maybe 10 of them on Tonga. And you have to factor in that they might not be able to transmit under the conditions they're in, because there are probably electrical grid problems. And they might have portable handset radios, but assuming those weren't lost or destroyed in the disaster, a lot of those rely on repeaters, and the repeaters might be non-functional right now.
So while they might help, I'm not surprised if they can't solve everything.
