It's our final #FieldWorkFriday of the season! Today, we revisit Nikolai where our local school partner 🏫 allowed the team to build the tower shown here. It receives the data streamed by radio wave 📻️ from 2 remote stations, K20K and L20K, each about 40 miles from Nikolai. Stay tuned 📡 for TriviaTues

Happy #FieldworkFriday! We maintain seismic stations at several of Alyeska's Trans Alaska Pipeline System pumpstations. This week the field team upgraded the data digitizer (which makes data ready to transmit) at station PS08 and performed "shake tests" to ensure it would alert Alyeska's systems.

What’s Shaking Alaska?! We’re often asked if the Earthquake Center is able to detect large earthquakes from around the world, and the answer is yes! When a large seismic event occurs, the seismic waves often travel over most of the globe. Listen to how this affects our Alaska: buff.ly/tbPANqt

The title is “What's Shaking Alaska?!” and the text reads “Week of August 26-September 2, 2026”. A map of Alaska in the background shows dots where earthquakes occurred. Other text reads “About 630 earthquakes were detected, and 2 earthquakes reported felt.” A circle with an arrow pointing to it is labeled “The largest was a magnitude 5.2 earthquake on August 21, south of Nikolski.”
