The biggest quake was in West Java, reflecting the forecast move into Java but risk location profiles were too narrow.

The ever increasing low level volcanic activity seems likely to have weather implications.
Quakes have strengthened on 3 September.
Moderate steady solar quake driving conditions continue on 3 September.
Excellent location success in Guam.
Continuing isolated Mag 6 activity is possible.
Tonga, Baja California are added to Mag 6 risk areas.

Quakes were picking up on 3 September.
Northeast of Guam 5.5 was biggest and excellent location success in a difficult forecast location.
Extending the period to 4 September was justified.
South Sandwich Islands 6.0 was the biggest quake of the period but no location success.
Galapagos Islands shield volcano Fernandina erupted and is highly likely to be fountaining lava and to increase on 8 September.
The forecast period had ended by 5 September but quakes continued to be active.

The August outlook for quakes and volcanos to pick up in September looks like happening.
A strong quake period is due 8 September and a big Southwest Pacific volcano may add to the ever growing list of active volcanoes.
