Breakout Sessions: Exceptional scientific opportunities and integration with other projects. We have two one-hour breakout periods and people are expected to switch halfway through. Charge to Breakout groups:

• Discuss scientific opportunities addressable through Alaska/Canada deployements
• Based on the scientific opportunities, what recommendations should be made for facility design or operation.
• In each area, what opportunities exist for synergy or cooperation with other programs, especially GeoPRISMS.

Breakout Session 3A: Slab and mantle structure and dynamics

14:00 Discussion (1 hour)
15:00 Discussion (1 hour)

Breakout Session 3B: Exploring the genesis zones and Earth's response from great (M > 8) earthquakes

14:00 Discussion (1 hour)
15:00 Discussion (1 hour)

Breakout Session 3C: Accessory measurements and enhancements of the facility instrumentation

14:00 Discussion (1 hour)
15:00 Discussion (1 hour)

Session 4: Active processes modifying the continent

16:30 Volcanism and magmatic processes (Brad Singer and Mike Lisowski)
17:00 Discussion
17:15 Earthquake processes (?? and Rowena Lohman)
17:45 Discussion
