What was the last volcanic eruption?

As the text cut off is in May 22 2022, the most recent volcanic eruption after this date is the eruption of Mount Yasur on Tanna Island in Vanuatu, which began on August 19, 2022, and is ongoing as of my knowledge cutoff in early 2022. The volcano has been experiencing strombolian and ash emissions, with lava flowing down its cone. Volcanic activity can sometimes be ongoing and continue beyond one's knowledge cutoff, so I recommend checking reputable sources to confirm the latest information.
