Major volcanic eruption of Shiveluch volcano in Russia. Ash columns up to 20k high. 

This article in New Scientist: with interesting clip.
"The Shiveluch volcano, one of Russia’s most active, has erupted, ejecting a huge cloud of ash that has coated nearby villages and triggered aviation warnings.  The volcano, which is in the country’s far eastern Kamchatka Peninsula, began erupting just after midnight on 11 April, launching a huge cloud of smoke and ash into the sky, according to Russian authorities. Its last major eruption was in 2007. Up to 8.5 centimetres of volcanic ash have settled in the village of Klyuchi, according to news reports."

Not much has come of the katla unrest but looking likely another eruption is imminent on the Reykjavik peninsula.

Yes the IMO has stated there is the increased likelihood of an eruption. It will be interesting to see if and where it occurs.

The bulk of the current activity appears to be in a similar location to the last eruption: https://en.vedur.is/earthquakes-and-volcanism/earthquakes/reykjanespeninsula/#view=map  

The 'magma intrusion', from the bits and pieces I have picked up anyway, is supposedly on par with the pre-2021 eruption in terms of volume, which is no guarantee that an similar sized eruption will be the result, but interesting times for sure. It seems something of a 'cycle' is going on. 

That was only a small eruption.
