Are you ready to get muddy? Our first Cores 2 Code (C2C) undergraduate summer research experience will take place in June 2025 @ Cal Poly Humboldt. We will delve into the earthquake and tsunami history of the Cascadia subduction zone through field, lab, and computational methods. See the link below!

Check out this Oregon public broadcasting video on our Oregon coastal geology work looking at past earthquakes and tsunamis. It’s only 10 minutes long but packs a punch! youtu.be/BIK3jfFvm_8?...

When the Cascadia earthquake hits, it’s going to be bad for pretty much everyone in the Pacific Northwest. One of the more frightening impacts of the “Big One” is that the Oregon coast will literally sink, heightening the effects of the predicted tsunami and permanently altering the coastline. But scientists are now using tiny fossils, called diatoms, to better understand the risks. Working on the Oregon coast, researchers have found that these diatoms offer clues to how much land will subside and how far a tsunami could wash inland after the next big Cascadia quake.

Wrapping up @cascadiaEQs fieldwork with the Cascadia Paleoseismology team. We collected new cores from Lagoon Creek for radiocarbon dating of tsunami deposits and conducted high-resolution surveying to work out tsunami inundation heights. ☀️ #norcal#cascadiaexplored#tsunamis

Our latest paper was chosen as an Editor's Highlight in @AGU_Eos! We use coastal geology to show that ruptures of the Patton Bay splay fault occurred together with 4 of 8 past Alaskan megathrust earthquakes during the last 4,200 years @theAGU #AGUpubseos.org/editor-highl...

Stratigraphic and diatom analyses suggest ruptures of the Patton Bay splay fault occurred together with half of the documented great Alaskan megathrust earthquakes during the past 4,200 years.

Check out this article highlighting our new Alaska splay fault paper. We know there are active splay faults in Alaska, but how often do they rupture with the megathrust? And what does that mean for local tsunamis? Our study sheds some light on this! t.co/8Ks5itPCG1

Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth’s largest earthquakes and tsunamis.

No better way to spend a Sunday afternoon than with @HokiesWBB. The atmosphere was 🔥 and Red Panda was spectacular #Hokies
