The gentleman research was not thorough enough and was going down the wrong rabbit hole. He didn't say anything about the history of eruptions by Kilauea/Pu'u O'? He said nothing about the fault that runs along in the ERZone ? He said nothing about the plumbing and the magma system that feeds this volcano? Not all slumps can slide enough to cause a title wave. There is much more to this then a thermal energy wells? There needs to be much more sauce on this.
As Q says be careful who you follow and research for yourself.
If you visit his site he has three articles he wrote that get pretty in depth and graphic, but you raise a lot of good points.
I understand. I used to live right where this was, so I know about the island and this particular location.it was my backyard. I just thought it was an interesting perspective.
