I saw a video that had the sound of the sonic boom it created. It was very loud. And this was from quite a fair distance from the blast. The blast was heard in Alaska. The shockwave went around the earth. Several sensing stations picked up the outbound and then the reciprocal inbound shockwaves.
That’s weird for a volcano. I was in Seattle both times Mt St. Helens blew. I never heard anything. The weather was clear the second time so I at least got to see it.
