During the Ruang volcano's climactic and destructive eruption on April 30th, a small tsunami was detected by an ocean buoy nearly 100 miles away. At first, it was assumed that this was generated by a pyroclastic flow entering the ocean, but further analysis seems this to have not occurred when the tsunami was generated. Instead, after discussions with several locals, I hypothesize that Ruang's underwater vent may have reactivated and produced a loud explosion more than two hours before its plinian eruption began. And this is what I hypothesize generated the tsunami during the volcanic eruption of Indonesia's Ruang volcano.
