Hunga Tonga-Hunga Ha’apai (Tonga, Tonga Islands): First images of ash-affected Nuku’alofa, the capital of Tonga, are coming from local people.
After the eruption, moderately strong ash rain of small lapilli set in covered all surfaces. The color of most particles, up to a few mm in size, is mostly brown to reddish-brown, described as „earthy“. This could mean that most of the ejected material might be from older lava rocks.

Scientists from NASA were measuring the power of the dangerous explosion that took place on 15 January.
„We come up with a number that’s around 10 megatons of TNT equivalent“, said James Garvin, the scientist at NASA’s Goddard Space Flight Center.

Based on preliminary satellite data from global weather radars, an estimated height of the eruption column likely reached an altitude of 39 km (128,000 ft)!
This detail has yet to be confirmed, but if correct, that’s the highest eruption plume in modern times ever.
…18 Jan:
Erosion at the volcano continues at a quick pace. Another significant morphological change can be seen in the latest satellite image of the island from 17 and 18 January compared to the previous imagery from 15 January.
The volcano has been eroded to two very small remnants of origin islands Hunga Ha’apai (left) and Hunga Tonga (right).
