Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • Some participants mention that there was a tsunami alert following the Tonga-Fiji earthquake.
  • Others argue that despite initial concerns about a tsunami due to the earthquake's shallow estimates, the actual depth was greater, which may have mitigated the tsunami risk.

Yeah, I heard about this. I also heard there was no tsunami.
 
There was a tsunami concern because initial estimates indicated a shallow quake, but it was actually deeper, so by the time the energy got to the sea floor, the vertical displacements were not too severe.
 
Just today somebody was telling me that their sister called them, and said they were under a tsunami warning in Hawaii at the time of the earthquake. Oahu I think.
