Data Tips

When the site loads, you are able to see all of the earthquake data from 2010 throughout the Coastal Endurance Array. You can interact with the data by:

Note, the color denotes earthquake depth, with darker blues representing deeper depths (up to 50km) and dark red representing shallower depths (0km). The yellows are in-between. The circles on the map are sized by the earthquake magnitude.

Questions for Thought

Orientation Questions
  • Across what geographic area are you able to observe earthquake data in this map?
  • What is the range of earthquake size (magnitude) in these data?
Interpretation Questions
  • What changes or patterns did you observe in earthquake location over this time period in the Northern Pacific Ocean?
  • Where did you see these changes or patterns?
  • What changes or patterns did you observe in earthquake magnitude over this time period in the Northern Pacific Ocean?
  • What questions do you still have about what we can learn about plate boundaries from earthquake data over time?
