I dont know what could cause this, but it would have to be pretty big. If it was created, there would be a start up procedure. Could the data at 13:55, 17:55, 19:25, 2:05, 6:55 previous to the event be testing or part of a start up?
Is there a more detailed picture of the previous waves? Almost looks like a motor idling after 19:25 or is that normal noise.
Just looking at it possibly being man made and using a mechanical perspective as it is familiar. Unknown in origins, there would still be a start up procedure and the previous wave would offer clues.

Also noted early pings not matching normal magma flow.
Message was sent, we are in control of the underwater spacecrafts or working with those who are on it and fired one up for confirmation.
Sure, that is way out there, but some people are going to think that.
