GNS Press Release... 

DART network proves invaluable in assessing tsunami threat


“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”.
