One of these videos includes mention of volcanic rock washing up on shore in Oregon. A viewer is going to send him samples.
Also - he calls out two places venting in the Pacific but you can see two more near the bottom. In a later video (I’ll look) he points out that his viewers saw the two other areas and reported it to him.
Great...do you manage a ping list on such activity? If so, could you add me to it? Thanks.
