It's our final of the season! Snows 🌨️ have started in the Interior, but the field team still headed out today to spend the week swapping out dataloggers at all of our pipeline stations 🚉 .
Today, we revisit Nikolai to show you what a relay station is. Our local school partner 🏫 allowed the team to build the tower shown here to receive the data streamed by radio wave 📻️ from 2 remote stations, K20K and L20K, each about 40 miles from Nikolai. The installation included hooking up a power system and satellite comms with a router.
Next week we kick off TriviaTuesday! Stay tuned 📡

Good morning, Alaska. We have reviewed a magnitude 4.5 that occurred on October 1, at 6:46 AKDT about 81 miles S of False Pass and 15 miles depth. At this time we haven't received any felt reports.

Large earthquakes and tsunamis often go hand in hand in Alaska. If you live in, or ever visit, a coastal community, knowing where to go before a tsunami hits could save your life!
We are excited to announce a new, one-stop interactive online map tool that offers a variety of tsunami hazard resources for 66 Alaska coastal communities, and counting. This is the first time all of this information is available in one place.
The new Tsunami Map App shows what is currently available for different coastal communities, and can include potential flood zones, community-created evacuation lines, safe assembly areas, TsunamiReady status, and more. Links to resources are listed for each community, such as hazard assessment reports, maps, and GIS data. Zoom around the map to check your favorite coastal community, and use the resources to make a safety plan.
This handy tool was funded by FEMA. The map interface was designed with our partners at the Geographic Information Network of Alaska, and packed with information built from decades of work with community, state, and federal partners.

We love meeting with people to talk about what we do and how they can prepare for the next significant earthquake. On Saturday, we sent 2 staff to the MatSu Emergency Preparedness Expo. Where do YOU get your earthquake information from?

Good morning Alaska! We have reviewed a magnitude 4.2 earthquake that occurred at 6:55 AM AK time. This earthquake was located 20 miles W of Kantishna and 3 miles deep. No felt reports have been received at this time.

It’s ! Field team members Shah Khan and Cade Quigley visited Nikolai recently to build a new relay station from the ground up! Thank you to Top of the Kuskokwim School for hosting the new station. Seismic stations K20K and L20K had been unable to send data for a while as we switched to a less expensive satellite system. Now they both send data via radio to Nikolai (you can see the two comb-like radio antennas at the top of the pole), then to the Earthquake Center via satellite. Khan and Quigley also stopped in for a presentation to Top of the Kuskokwim School students to share what the Earthquake Center does, and to practice earthquake safety!

The largest earthquake last week was a magnitude 6.5 on September 17th in the Aleutians west of Nikolski, which is about halfway between Adak and Unalaska.
Only eight people reported how much shaking they felt to the U.S. Geological Survey “Did You Feel It?” website. The responses, coming from 200 miles or so on either side of the epicenter, ranged from level II to level III. This translates as weak shaking with no damage.
The term “magnitude” is widely known, but the shaking intensity that people experience is actually far more relevant. A magnitude 6.5 earthquake in Mexico earlier this year caused building damage, landslides, and deaths. People reported shaking intensities up to seven, associated with moderate damage.
Many factors influence how strongly a region or individual feels shaking, and magnitude is only one of them.
There are tens of thousands of earthquakes in Alaska every year, most of which no one feels. We review all of them so that we can provide a clearer view of where earthquake hazards are, and help scientists answer questions about patterns in earthquake behavior. Reporting the level of shaking you feel helps translate magnitude into improved understanding of earthquake hazards.
To learn more about what factors affect shaking intensity, explore the News section under the Resources tab at earthquake.alaska.edu.

We have located a magnitude 3.5 earthquake that occurred at 6:20 AK time this morning. The earthquake was located 35 miles NE of Ambler. We have yet to receive any reports of this event being felt. You can learn more or report feeling it at:
