Pacific Summary. 27 May 2025 - 15 June 2025
Spaceweather was driven by a very long period of coronal hole windstreams with a brief Kp8 aurora on 1 June following an M8 flare from Earth facing sunspot AR4100. Long period coronal hole windstreams tend to produce volcanic conditions and the period came up with the goods. Big eruptions at Etna, Sakurajima, Fuego and moderate new eruptions at Kamchatka Peninsula volcanos Shiveluch and Kliuchevskoi gave strong evidence of the coronal hole/volcano link. Brief eruptions at Kilauea are coming frequently in 2025 and a waste of time forecasting. Spectacular 300 meter high lava fountains on 4 June soon faded but already another eruption is nearly underway as the volcano rapidly contracts and expands. The forecasters couldn't pin down any quake risk locations so didn't offer a detailed forecast. This is typical during volcanic periods when quake precursors and quakes themselves are weaker. Regardless a few Mag 6 quakes came during the period. The region south of New Zealand never went Mag 6 during the period but will remain a Mag 6 risk during the next few forecast periods. 31 May.
