Vanuatu/NE Tanna 5.9 9.10am
Solar conditions arrived on cue.
Pacific quakes responded on 24 November, including White Island 5.9.
Very rare double Mediterranean 6.4, 6.0 quakes and Etna eruption centered the action away from the Pacific during the period.
Pacific quakes never made it to high magnitude or frequency but kept steadily coming as spaceweather conditions lingered for several days.
Solar Minimum spaceweather is typically weak and 2019 is the weakest in a century according to NASA scientists and others.
Quake periods are also tending weaker in 2019 with few Mag 7 Pacific quakes and major hurricanes this year, despite the well publicised Japanese typhoon at the Rugby World Cup.
Late quakes at Atacama and Vanuatu were outside the forecast period but good location success.
A brief mild quake period is possible 8-9 December.
