The passage of sunspot AR12297 made this a very stormy forecast period. Cyclones Pam, Nathan and Olwyn powered up early in the period. Nathan re-powered late in the period. The big St Patricks Day solar storm came courtesy of AR12297, the angry sunspot hurling out some powerful flares. Global and local quake activity picked up with AR12297 but luckily no major shock. Early local quake activity didn't get as big as forecasted but much Mag 3+ activity was in the forecasted locations, particularly Taumarunui. On 18 March quakes became widespread and tidal with the big lunar perigee, many quakes falling just below Mag 4. Global quake locations were a moderate success. Indonesia and Solomon Islands active. The Caribbean was quiet but nearby Mexico active. The addition of Kermadec Islands worked, going off early on 22 March. Volcanoes became active on 18 March, many minor eruptions on 20 March. 13 March. Eastern Taranaki Bight 4.3, 3.00pm. 15 March. Taumarunui 3.8, East of Taihape 3.7. 16 March.
