Forecasted big Northern Hemisphere quakes were being confirmed. NZ and South Pacific were quiet. On 30 May the period grew inevitably bigger. Japan 7.8 was given a deep rumble. Califorinia also had moderate quakes. On 1 May action quietened but still with big residual quakes near Oregon. Moderate NZ quakes picked up late in the period. Japan had a big volcanic eruption at Shindake. Nearby Sakurajima also erupted. These eruptions were successes from the 24-27 May forecast period. Volcanoes were otherwise quiet or no data available. KIlauea is in minor eruption apparently.(?)
