Researching earthquakes, active faults and seismic risk 🌎🫨 at the Geological Survey of Canada 🇨🇦 | Adjunct professor at UBC and UVic | Opinions are my own
Trying, but failing, to keep a straight face while discussing the “party pickle” in a meeting.

(Pickle is a file type in #seismology, and a party is the name for a group of detected #earthquakes in the software package we’re using).

Check out this new paper from my student Meg Patchett, understanding how emergency managers and first responders can use earthquake risk information in real time after a major event 🌎
When every minute counts, RED-E delivers rapid post-earthquake insights—bridging the gap between science and response in Canada.

That wave was a paid actor. 🌊

But seriously, thanks to @nredick.bsky.social and our other Apply-to-Sail participants for capturing some cool moments on #PACSAFE2025!

Yesterday afternoon we finished the final #Ocean Bottom #Seismometer recoveries for #PACSAFE2025, and started redeploying along the Explorer Plate! Here’s a look at our “full house”, with 23 instruments on deck.

PS - Earthquake hazards are inevitable in California, but we can lower our seismic risk by decreasing our exposure and vulnerability to those hazards.

Sawyer Island located in the middle of Tracy Arm, 7 km downstream the landslide, shown here before and after the estimated 30-m high tsunami! 🌊😱

The isolated tree was particularly resilient! 🌲💪

Hurricane Erin is the Atlantic's fifth Category 5 hurricane since 2022—continuing an astonishing pace of high-end storms across the ocean basin.

Another active fault on Vancouver Island - our new paper documents evidence for at least 3 Holocene earthquakes on the Beaufort Range fault
🌍The Beaufort Range fault is ACTIVE!
This right-lateral oblique Beaufort Range faulting occurs >100 km farther North than previously documented faults in the Cascadia forearc.

The biggest #wildfire on the #OlympicPeninsula in 74 years right now. Such a gorgeous piece of preserved #wilderness under threat, but inspiring to see how hard-working folks are working to protect structures.

Eruption #5
Mount St. Helens has been quiet since July 22.

12:17 p.m.: Harmonic tremors begin.
1:30 p.m.: USGS and UW warn an eruption is likely within hours.

4:26 p.m.: The mountain obliges—pyroclastic flows down the north breach; ash column to 44K feet, drifting northeast.

Alaska Earthquake Center posted a nice explainer video with some of the video reconnaissance following the recent #landslide and #tsunami in Tracy Arm, south of Juneau, Alaska. It’s a whopper! 🧪⚒️

What a success!
We recovered all 29 ocean bottom seismographs, after 20 months on the seafloor, no losses! The ship fantail is full of seismographs. Photo shows co-chief scientist Shawn Wei and I with the flag from the last instrument,signed by the science party of the December 2023 deployment cruise.

It shows the landslide that collapsed onto South Sawyer Glacier and Tracy Arm Fjord, about 60 miles southeast of Juneau.

Today we’re recovering #Ocean Bottom #Seismometers from near Cape St. James at the southern tip of #HaidaGwaii. They’ve been listening for a year and we hope they’ll tell us more about how the Pacific, North America and Explorer #TectonicPlates interact in this complex triple junction.

Some critters hitched a ride on our ocean bottom seismometers for #PACSAFE2025, but we don’t know what they are. Found in the north east Pacific off the coast of BC, Canada, from depths of around 2000m. Any #biologists or #marine #scientists have ideas? @whoi.edu ?

Had a sporty day yesterday on #PACSAFE2025: an instrument released early so we had to make a 3hr detour to get it before the storm carried it off. 4m seas by the time we got to it, but the awesome deck crew of the 🇨🇦 #CoastGuard Tully pulled it off no problem.

Today we start PACSAFE recoveries!
