CarpeDiem 512 Posted January 18, 2022 Share Posted January 18, 2022 GNS Press Release... DART network proves invaluable in assessing tsunami threat Quote “The first sign of unusual activity came when the New Zealand DART buoy closest to Tonga triggered at 5:48pm. We could see that a significant signal had been picked up by the sensor. This was about 30 minutes after the eruption (the time we had previously estimated to be about the travel time of a tsunami from the volcano to DART G) so we were immediately pretty confident that this was a volcanic source tsunami. “From there we triggered the second closest DART to the volcano, DART F, and when we saw a significant signal recorded there too, we proceeded to activate the entire network”.
