One of the most damaging volcanic eruptions from 2021 was the event on La Palma in the Canary Islands. The eruption lasted for months and ended up burying a significant part of the communities that had built up on its slopes. Thankfully, it was an eruption that didn't end up taking lives, but the damage was estimated to be at least $1 billion. As it turns out, the eruption itself compared to others was relatively small, but the human impact was much larger.
