This is either Fissure 7 or Fissure 21 on May 26th. Sorry, both of these fissures were right next to each other and they both look extremely similar and both had a mini fissure right to their left so they are hard for me to tell apart. I will try, when time permits, to nail it down with input from other people. None of these videos have been shared before.
Apologies for the video quality as everything was filmed on a Samsung Galaxy phone. It was the only thing I had to use after we lost our belongings in the eruption.
