Hello,
it is fascinating, that the air blast wave from eruption of Hunga Tonga–Hunga Haʻapai volcano on 15th jan 2022 04:14:14 UTC could be registered in germany with a simple BME280 pressure sensor.
With 1235km/h for the speed of sound and a distance of approx. 20000km the time to reach europe is in the order of 16 hours…
My own sensor showed this even more clearly, but how can images be uploaded here?
The eruption is described in
Hunga Tonga-Hunga Haʻapai ist ein Vulkan auf der Insel Hunga Tonga, die zum Inselstaat Tonga im Pazifik gehört. Die Vulkaninsel liegt in der Haʻapai-Inselgruppe, etwa 24 Kilometer südsüdöstlich von Fonuafoʻou (auch bekannt als Falcon Island). An ihrem höchsten Punkt ist sie 149 m hoch.
Ende Dezember 2014 brach der Vulkan zum zweiten Mal innerhalb von fünf Jahren aus und bildete eine neue Landfläche zwischen zwei Inseln, die zuvor von ihm geformt worden waren. Das Eiland wird hauptsächlich durch ...

Hunga Tonga–Hunga Haʻapai was an uninhabited volcanic island that existed in the South Pacific from 2009 to 2022, located about 30 km (19 mi) south of the submarine volcano of Fonuafoʻou and 65 km (40 mi) north of Tongatapu, Tonga's main island. The previously twin islands of Hunga Tonga and Hunga Haʻapai were merged by a volcanic eruption in 2009, and a more explosive eruption separated the islands again and reduced them in size in 2022. The erupting volcano is part of the highly active To The v...

Nice, i was already wondering from what direction the pressure wave came.
