Panel Discussion:
The following are proposed for the theme questions for the panel discussion:
1. What will EarthScope gain from it’s multidisciplinary nature, making the whole
greater than the sum of the parts?
2. What integrated data products do we want from the EarthScope facility?
3. What would you like to see as the EarthScope legacy in the Great Basin?
