The main objectives of going to Denali were to learn about seismology and what seismologists do, the equipment used, and how seismologists use these tools to monitor earthquakes. We also wanted to understand what happens before, during and after earthquakes. We got to learn about the movements of the earth and how these forces have shaped the Denali region. Lesser goals included learning about historical and active geology, learning to tell the difference between good (signal) and bad (noise) data, and learning how to work together as a team in the field.
In Denali we camped at Murie Science Leaning Center's Teklanika camp. There we prepared to set up nine seismometers in different sites. After readying ourselves we embarked to Kantishna on a long van ride filled with animal sightings. Upon our arrival at Kantishna we set up six seismometers spread roughly 100 meters apart. After that we set up three more stations further apart, that we would use to help us confirm hundreds of earthquakes. Aside from the hundreds of local Denali earthquakes there were a few events that stood out in our data. For instance, 566 kilometers away from station AYURT a 5.6 global earthquake occurred in the Gulf of Alaska. Also, a different type of ground movement was picked up, a large piece of ice falling off a Glacier. After just two days the stations picked up an estimated 321 small earthquakes.
