A wonderful new paper (Shugar et al. 2026) on the 150 million tonne Tracy Arm landslide and tsunami will have profound but challenging implications for the management of risk in fjords around the world in an age of increased tourism and rapid climate change:- eos.org/thelandslide...

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.

Fascinating new piece by @sipappas.bsky.social looking at the geology behind the geopolitics: 🧪

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.

Sample data from the NASA-ISRO SAR (NISAR) L-band imaging radar is now available from the NASA EarthData system. These are preliminary products with some caveats but include an interferogram for the November 2025 volcanic eruption in Ethiopia. www.earthdata.nasa.gov/news/nisar-s...

NISAR L-band data products are now available, giving users a first look at data products from NISAR acquisitions.

⛏️🌋 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

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...

‘There’s no monitoring of earthquakes’: new British Columbia pipeline could spell catastrophe, experts warn

Project on ‘very poorly understood’ terrain and likely to pass through Rocky Mountain trench, which researchers say poses immense geological hazard
