It's among the world's largest active volcano's, and most recently erupted in October 2021. This pic is from when I hiked up there in the end of August / beginning of September, 2021.
By the way, the caldera in the middle of this post is inactive. The one that blew up is the one in this pic (the smoke/steam rising from the ground in the back)
