Note:Pressure waves from Hunga Tonga-Hunga Ha'apai's volcanic explosion (±0414Z) arrived late 0605 (1305Z) at Yellowstone's seismic network. Attachment from Mara Reed. On 24h thumbs started to become visible only from 0645 (1345Z).

That is nuts. Prayers for everyone in Tonga.

These should be the airwave coupling into the ground as opposed to any direct seismic arrivals, which would have occurred hours earlier. I think the arrival times listed here are incorrect, the ones I checked all fall roughly 0605–0606. See
