Correct! We will enter you into the April drawing for Earthquake Center goodies.
The correct answer is the 1990s, when the tsunami program in Alaska first started producing inundation maps for coastal communities. @santini.ohnodisaster.net good job coming up with the correct answer, we'll enter you into our April drawing!
Welcome to your final month of Trivia Tuesday📝 before FieldWorkFriday comes out of hibernation🧸! Let's dive deep into tsunami awareness 🔊this week. As usual, first to get the right answer🏅will be entered into our drawing to win some AEC swag! (Hint: search our website for the answer!)
When we can plug a seismic sensor directly into power and cooms, it makes for a simple install and uninstall. This sensor is getting a little TLC, and was luckily easy to access, right on campus. It's featured on the bottom floor of the building in Fig 2 of this story: https://bit.ly/4hTtxIo
The correct answer today is to pull over and stop if it is safe, but stay inside your car. Try not to stop under trees, light posts, power lines, or signs. Avoid bridges, overpasses and tunnels. Learn more safety tips on our website earthquake.alaska.edu/prepare.

The title is What's Shaking Alaska?! Week of February 11-18, 2026. A map of Alaska in the background shows dots where earthquakes occurred. About 650 earthquakes were detected, and 8 earthquakes reported felt. The largest earthquake was a magnitude 5.1 on February 13 in the western Aleutian Islands.
This week's radio episode highlights the partnership we have with the Alaska Division of Geological and Geophysical Surveys, from landslide monitoring to tsunami preparedness and more! https://earthquake.alaska.edu/sites/default/files/021826.wav
Sorry to hear you had trouble! Here's how to find a station on the map: in the map toolbar in the upper right, click on the "list" icon (horizontal lines). This opens an alphabetical station name list, then scroll or use "ctrl or cmd + F" (whatever "find" command your device uses) and type the name.
Today's correct answer is St. Paul Island. Explore more stations on our network map earthquake.alaska.edu/network.
Giving a nod to stations in our network this week! Somewhere on our website 🔎, we have a network map 🗺️ with clickable icons that link to details on each station. First one to submit the correct answer gets entered in our spring drawing for AEC swag! ("somewhere in Alaska" does NOT count 😂)
