The 2 main feeds are MBL.is and RUV. All other channels afar.tv etc just feed off these cameras.
Currently, the remote cameras do not have a good field of view, after all they didnt know where the first lava would flow.
Give it a coupe of days, they will move their equipment to a better location. They use steerable cameras and solar panels, which microwave back to Reykjavik.
Youtuber Just Icelandic has quite a good channel as well.
But in a couple of days it will get better.
