West of Mahia 3.8 6.05am Plenty of big action north of New Zealand hasn't come here yet. Local quakes have been very busy following the South of Kermadecs 5.6, 5.3 double quake. Possibility for isolated Mag 5 quakes still exist on 4 June. North Island East Coast is higher risk. Isolated quakes may continue ahead of a possible peak on 7 June. Update. 5 June 11.20pm. 5 June. Kawerau 4.1 11.08pm; 3.9 & quake swarm. Local quakes were quiet during the typically less active middle section of any forecast period. Recent South of Kermadec Islands activity is now moving into Bay of Plenty as a possible quake peak on 7 June approaches. Possibility for Mag 5+ quakes continues 6-7 June. Kawerau is higher risk. Possibility minor eruption White Island. Update. 7 June 12.00am. Local and Pacific quakes were quiet on 6 June...except Kilauea. The big Kawerau quake swarm has settled down on 6 June and a good indicator of a volcanic pickup. Today Geonet have announced heating since 31 May at Ruapehu. The 24-27 May Aotearoa Summary speculated volcanic heating in New Zealand was near so today's announcement is good confirmation. The Ruapehu heating gives credit to the addition of White Island as a steam eruption risk...although no eruption has taken place yet. The forecast period is heavily volcanic in the Pacific. Bay of Plenty remains highest risk location on 7 June. The forecast period is likely to close soon. Update. 7 June 3.30pm. 7 June. West of Levin 3.9 1.55am Ward 4.1 12.24pm Moderate quakes very late in the period have given some substance to the forecast. Previously not much was happening outside of volcanic heating/swarms in Bay of Plenty and Volcanic Plateau. Solar conditions are fading away today. Volcanic activity often comes at the end of forecast periods or soon after. Additionally, South of Kermadecs is a Pacific hotspot during the period. Late quake or volcano action in Bay of Plenty/Volcanic Plateau seems possible on 8 June. This Service is offline until 11 June. A Summary for the forecast period will be posted later.
