Welp here we are again, fresh out of Archaeologists for Skype a Scientist matches.

This fall, we have matched 248 groups with Archaeologists for online Q&As. I have 38 more groups who need a match, but I'm out of Archaeologists!

Archaeologists! Please volunteer

I'm running for something!

The world is a complicated and increasingly scary place. Decisions made at the local level will have real impacts. That's why I'm running for a seat on the Tompkins County Legislature.

If you can afford to pitch in, I'd really appreciate your support.

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.

In which I beg archaeologists to sign up for the fall semester of Skype a Scientist, because we're getting buried in requests for your area of expertise.

I run @skypeascientist.bsky.social which matches scientists w/classrooms, libraries, etc for Q&As.

We match First Lego League teams too. This tends to wipe out one category of scientist bc so many teams sign up for the same category (this year, archaeologists). We're almost out of archaeologists.

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

AVO does not have Edgecumbe at an elevated color code right now. It had a swarm there a couple of years ago, but it's had low-level activity for the last couple of years.

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:

There is no supervolcano here, despite claims in disreputable tabloids

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.

Natasha Kozyreva, treasured Alaska Earthquake Center family member, passed away on August 30th. She leaves an enduring legacy. Researchers using our catalog are working with data shaped by Natasha’s careful hand. Read more about her: https://earthquake.alaska.edu/staff-spotlight-natasha-kozyreva

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
Map of Alaska earthquakes during the week of August 27 through September 3. Summary in text says 300 earthquakes detected, magnitude 5.0 earthquake near Kodiak had about a dozen aftershocks, and a magnitude 5.8 in the western Aleutian islands was the largest earthquake this week.

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!

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.
