Early warning systems on Raoul Island to be repaired after earthquake

Early warning systems on Raoul Island, one of New Zealand’s most integral sites for monitoring earthquakes and tsunami, will undergo critical repairs after an earthquake occurred in the area last Friday. The tidal gauge at Raoul provides critical early warning for the Pacific Islands. On March 5 a tsunami wave took about 44 minutes to travel between the Fishrock gauge and the Nuku'alofa gauge.
