I’m quoted in this excellent Scientific American article on the incredible Zagros mountains, the focus of much of my PhD and postdoc research. The Zagros’s unique tectonic history explains the Gulf’s rich oil and gas reserves and ultimately the Gulf itself, including the narrow Strait of Hormuz.

February 21, 1993, died on this day aged 105 years, Danish seismologist Inge Lehman. She discovered that the Earth has a inner core announcing it in 1936 with the shortest title for a paper ever: P' - after the seismic discontinuity between core and mantle shown by the P-waves

⚒️🧪Fiery Mud Volcano Eruption! The Daşmərdan (Dashmardan) mud volcano in Azerbaijan erupted ~16:50 on the 30th Jan 2026. The eruption lasted ~15 mins and was accompanied by a pillar of flame several hundred meters high. Daşmərdan had previous documented eruptions in 1866, 1954, 1976, 1986 and 2011.

326 years ago tonight (9 p.m. Jan. 26, 1700) a M~9 Cascadia subduction earthquake rocked the west coast from #VancouverIsland to northern California. The Juan de Fuca Plate slipped up to 20 m, causing a large tsunami, strong shaking and landslides www.earthquakescanada.nrcan.gc.ca/historic-his... ⚒️🧪

Exciting to see lake tsunami research in the spotlight! I joined CBC to talk about our work at Chehalis Lake and how we can go about better understanding lake tsunami hazard here in BC. #Geohazards #LakeTsunami #ScienceCommunication

⛏️🌋 Dreamy views of the Cascade volcanoes this weekend from the southern tip of Vancouver island: that’s Mt Baker looming behind Victoria, and Glacier Peak poking through the clouds behind Race Rocks

On FB, Yukon Geological Survey posted some spectacular photos of landslides & snow avalanches triggered by the magnitude 7.0 earthquake on Dec 6 in the St Elias Mountains. Here are some of my favs. @geocron.bsky.social @theronfinley.bsky.social @davepetley.bsky.social @ksvenenvig.bsky.social 🧪⚒️

A follow up with another few days of events. Now relocations of almost 600 earthquakes. These preliminary results suggest the main shock lies on a different fault a km or so SW, with most aftershocks tracing the possible Totschunda-Fairweather Connector Fault. Thoughts, @julieelliott.bsky.social?

Very preliminary relocation results from the December 6th #Alaska - #Yukon #earthquake, The Hubbard Glacier Earthquake. Double difference locations (343) derived from catalog epicentres (372), both manual and automatic. Squares are catalog epicentres, circles are relocations.

I was on CBC's Yukon Morning today speaking about Saturday's Hubbard Glacier M7.0 earthquake and its aftershocks. Coincidentally, I got an audible alert on my phone for the M7.6 earthquake in Japan while we were on air! www.cbc.ca/listen/live-...

My take on why the proposed northern pipeline is incredibly risky without 1st doing some basic geological due diligence. BC’s N Coast & interior are criss-crossed with faults but seismic & geodetic monitoring is rudimentary and we simply don’t know what’s active. www.theguardian.com/world/2025/d...

STORY: 4 years after the 2021 floods and landslides, major promises linger. There is no federal money to stop a future Nooksack Flood of Sumas Prairie. There is no national flood insurance program. And BC's new Flood Strategy lacks the funding to actually see it through. thetyee.ca/News/2025/11...

Fish in the forest, seaweed in trees? Yes - 13 years ago tonight, the M7.8 #HaidaGwaii earthquake generated the world's largest #tsunami of 2012. Runup to 13m in some inlets left seaweed in trees and fish in the forest. If you are near water and feel long and strong shaking, go to high ground. 🧪🌊⚒️

Tuesday's 530am #earthquake was a well-timed follow-up to #ShakeOutBC. The early timing and quiet schools resulted in the event being nicely recorded on all #SchoolShake instruments. If you felt it, you can still report it here www.earthquakescanada.nrcan.gc.ca/dyfi-lavr/fo...
