I found Bushcraft Bear on the first day of eruption. He does great reporting on the eruption and the island. He bikes all over the island, uphill, downhill to get good viewpoints.
About a week ago, he caught on camera a cloud formation over the volcano that was amazing, Turns out they are ‘gravity waves’ and can also be seen on satellite. He is worth watching, gives a short update wideo, twice a day.
Start at about 2:25 to see the cloud formation.
Standing wave or wave cloud, not gravity wave. Happen nearly every day there’s wind blowing and moisture in the air where I live.
