It's #FieldworkFriday! Our fantastic field team did their annual checks of seismic stations along the Trans Alaska Pipeline System, one of our long-standing partnerships - going strong since 2004! The team's road trip headed all the way up to Prudhoe Bay, inspecting 6 of the northern pump stations.

The Alaska Division of Geological & Geophysical Surveys is hiring a volcanologist who would work with the Alaska Volcano Observatory. A fantastic opportunity to work with great people and study very active volcanoes. Details in link below. Applications close on Oct. 1. ⚒️🌋🧪 bit.ly/3IkqN9n

⚒️ 🧪 If you've seen breathless reporting about a seismic swarm near a "supervolcano" in northern Nevada, don't worry: that is just where Yellowstone was, 15 million years ago. There is no supervolcano there now. But the swarm, and the geology here, is pretty neat! Read about it in our latest post:

Its good to see real, in-depth science being done to debunk the harmful myths about trans youth. Veronica Esposito takes a look at an eleven year study in this month's Journal Club.

Natasha was one of the most knowledgeable women I have ever worked with. She was so fast & knew Alaska seismicity so well. She had such pride in her work & helped create one of the best datasets in the world. I will miss her so much.

What’s Shaking Alaska?! Welcome to your seismic update from across the state for the week of September 3. Last week, Earthquake Center staff were at the Southeast Alaska Tsunami and Seismic Hazards Workshop in Ketchikan. Listen to these important takeaways about preparedness: https://bit.ly/46rx6jN

What’s Shaking Alaska?! Over the past week, we recorded about 420 seismic events. 4 were reported as felt. The largest earthquake was a magnitude 4.9 south of Sand Point—an aftershock of the July 16 magnitude 7.3 earthquake.

This scenario tool helps show how an early warning system could benefit Alaskans in a real, and measurable, way. Here's a modeled scenario of a realistic, magnitude 8.3 offshore earthquake near Anchorage. 10 sec–1 min of warning time in advance of heavy shaking is achievable.

Earthquake Center researcher Alex Fozkos analyzed a variety of Alaska-specific earthquake scenarios to determine how much EEW time could be possible. The recent magnitude 7.3 could have generated ~10 sec of warning time for Sand Point, and 20 sec for King Cove, the two closest communities.

Knowing what an earthquake early warning (EEW) system is capable of is a critical first step in making it work for Alaska. When a large earthquake starts, an EEW system assesses data within seconds and sends an alert, providing critical time for people and infrastructure to take safety actions.

Happy #FieldworkFriday! Kudos to our field team for bringing two key stations back online: SPIA on St. Paul Island and DCPH in the Deception Hills. 🙌 SPIA helps locate quakes along the Aleutians and offshore of western Alaska. DCPH fills one of the largest gaps in our network along Alaska's coast.

Asking for myself: does anyone know an Indigenous women in science at an Ivy League? I am looking for mentoring around navigating the specific elements of Ivy institutions as an early career rooted in community work… and I don’t seem to have any one to ask for advice. It’s lonely out here 🥺

It's #FieldworkFriday! Director of Operations Austin Holland joined the team working from Cordova this week, his first stint at helicopter fieldwork. Constant extreme winds at BARK ripped off the radio antenna. The team tucked a new antenna inside the hut & fixed the wall. BARK is back!

Learn more about the Tracy Arm landslide on our Significant Event page at https://earthquake.alaska.edu/event/025a7d7cil/detail

A striking increase in earthquake activity near the landslide started >1 day before the slope failed. Thousands of small magnitude earthquakes steadily increased in frequency to a near constant just before the event. Studying clear precursor sequences like this one could help us in early detection.

The Tracy Arm landslide in Southeast AK was potentially the largest in AK in a decade, triggering a local tsunami that stripped vegetation off islands and mountainsides dozens of miles away. AEC scientists continue to sift through data to uncover details about seismic precursors to the landslide.

Over the past week, we recorded 360 seismic events. 4 were reported as felt. The largest earthquakes were both magnitude 4.7 on August 14th—one near Yunaska Island, and the other just north of Westdahl Peak, both in the Aleutian Islands.

Great thread from an expert studying landslides in Alaska 🧪⚒️🪨

The glacial lake outburst flood at Mendenhall is still just beginning and waters are already higher than last year's damaging peak. Depending on how quickly the lake drains, it could unfortunately be a record flood for Juneau. I hope residents have had the support they need to prepare and evacuate.

Hey, as a librarian I need to tell you: Our funding depends on usage. So go ahead and check out that book even if you don't think you'll finish it. No one will know. Check out that DVD even though you might not like it. Get ambitious in your quest for knowledge.

It is likely that a large, tsunamigenic landslide occurred in Tracy Arm inlet, in Alaska on 10 August 2025 at 5:30 am. Seismic trace from the Alaska Earthquake Center, Satellite image (dated 7 August 2025 - before the landslide) from @planet.com. eos.org/thelandslide...

On Sunday, tens or hundreds of millions of tons of rock fell into Tracy Arm, a deep, narrow fjord south of Juneau popular with sightseers. It set off a colossal tsunami, stranding and nearly washing away a group of kayakers who had camped on a nearby island. alaskapublic.org/news/environ...

1. Texas Republicans are attempting to use the devastating floods to push... a trans bathroom ban. That's right, the emergency session which has been billed as primarily for flood relief is being used to sneak in anti-trans legislation. The latest from S. Baum. Subscribe to support our journalism

I hope everyone sees this story. Master Sergeant Logan Ireland, 15 years in, had an approved early retirement date for December & already began out-processing, even though he had rather remained in the military. Now, the Trump administration took even that back. www.advocate.com/news/air-for...

Goddamn. What a sobering and poignant piece of conceptual art. What an amazing artist.

Following the powerful earthquake originating off the coast of Russia, #UNESCO's early warning systems triggered a #Tsunami alert within just ten minutes. Read the full press release here: unes.co/ts26zj

After a 25-hour workday, I'm finally home from this #tsunami response! I have many thoughts to share soon, but most of them come down to "hey, maybe we shouldn't defund the National Tsunami Hazard Mitigation Program, which funds the vast majority of state-level tsunami work in the US!"

A peek behind the scenes of the @ktoopublicmedia.bsky.social TV control room tonight where we just competed 3 hours of non-stop live tsunami warning emergency broadcasting on Public TV across Alaska. #Alaska #PublicBroadcasting #PublicMedia #Tsunami #Earthquake

Reminder that the Tsunami Warning Centers are part of the National Weather Service. It would be nice to have them fully funded.

💯. There are many places in Alaska where there is very little cell phone or internet service, and it is usually pretty expensive. Public broadcasting is critical for these communities. They also need to be funded!
