Hunga Tonga-Hunga Ha'apai volcano explosive activity continues. Volcanic Ash Advisory Center Wellington warned about a volcanic ash plume that rose up to estimated 52000 ft (15800 m) altitude or flight level 520 and is moving at 05 kts in N direction
NOAA NESDIS provides a coverage of the Tonga eruptions with satellite imagery from GOES West and Himawari-8 satelites:

This view from the GOES WEST satellite gives a more 3D perspective of the huge volcanic ash plume that rose up to estimated 15800 m (52000 ft) or altitude or flight level 520 over the Hunga Tonga-Hunga Ha'apai volcano [all the satellites views:]
The shockwave of the Hunga Tonga-Hunga Ha'apai volcano eruption detected in Auckland, New Zealand, 2,000 km away from Tonga. The atmospheric pressure jumped 4 hPa and then fell almost 6 hPa all in about 20 mins [source, read more:]
The Tonga Meteorological Service released this photo of the Hunga Tonga-Hunga Ha'apai volcano eruption from orbit [source:]
This is a view of the area around the Hunga Tonga-Hunga Ha'apai volcano seen from the International Space Station before the major eruption, on January 13, 2022
This clip, according to the sources, documents the shockwave's 'boom' as heard in the Fiji islands, at about 700 km of distance from the Hunga Tonga-Hunga Ha'apai volcano [source:]
I happened to check my weather station and immediately watched for updates online: apparently the one highlighted in the chart may be a pressure (or "the" pressure) oscillation related to the Hunga Tonga-Hunga Ha'apai volcano explosion that reached Europe.
